Introduction Of all the berries, strawberries are the most famous. There is hardly a person in the world who would not admire her as much as they admire beautiful flowers. In ancient Rome, they believed that in memory of the girlish tears that rolled down the princess’s cheeks in large round balls, people began to call these berries strawberries, and when they forgot something or simply could not remember, they picked them dressed in a red royal robe fruits and tasted their pure and pleasant aroma. There are hobbyists all over the world who collect strawberries as passionately as other collectors collect works of art. I became interested in what type of strawberry grows in my grandmother’s garden, what nutritional properties do the berries have, why is it healthy? The object of research is strawberries. The subject of the study is the possibility of growing strawberries at home. The purpose of the study is to theoretically substantiate and practically test whether it is possible to obtain a strawberry harvest at home. In accordance with the purpose, object and subject of the study, I set the following tasks: Study the literature about strawberries. Find interesting facts, myths, legends and beliefs related to strawberries. Determine what varieties of strawberries are grown. Grow strawberries for Santa Claus for the New Year. Research methods: Observation Experiment Literature analysis

I Theoretical part 1 This amazing berry Strawberry, perennial herbaceous plant genus of strawberries in the Rosaceae family. Height 30-35 cm. Leaves are trifoliate, large, light green, ribbed, densely pubescent. Peduncles higher than leaves. The flowers are white, with 5 petals, usually unisexual; in cultivation there are varieties with bisexual flowers. The fruits (berries) are small (2-3 g), conical, pinkish-violet, with white flesh, sweet, spicy, with a strong specific aroma. Strawberries are quite winter-hardy, but prolonged frosts without snow cause plant death; It is not drought-resistant, grows and bears fruit better in light shade. Distributed wildly in Europe (with the exception of Italy, Southern France, Spain). Strawberries are cultivated in France, Italy, Great Britain, Germany and Russia. The calyx consists of five fused sepals, the corolla - of five free petals. Large trifoliate leaves are light green in color, located on stems 30-35 cm high. The flowers are usually unisexual (there are varieties with bisexual flowers in cultivation), five-petaled, white, with double perianth. Peduncles are higher than the stems. What is usually called a strawberry is actually an overgrown receptacle, on the surface of which there are numerous small fruits - nuts. The aromatic berry came to Europe in the 16th century. The French officer who brought the first strawberries home from Chile wrote to the royal cook: “I brought His Majesty fruits that relieve the heart from the suffering caused by state unrest. The aroma of these berries fills the soul with love, and the mind with fun.” The officer did not exaggerate the merits of unfamiliar fruits. Later, scientists found that strawberries rank first among all berries in terms of iron content, and the smell of ripe strawberries is due to the presence of more than 50 aromatic substances that can cause a surge of vigor and good mood.

Historically, the names of these two plant species have become confused and still cannot be unraveled. Even 300 years ago, forest and then garden strawberries began to be cultivated in Russia. And since in those days few people were strong in botany, they were confused and the berries of large-fruited strawberries began to be called strawberries. Why not mix it up if the berries are similar - both are sweet and tasty? Origin story garden strawberries(the same one that is now sold in our stores!) is shrouded in amazing adventures. The French officer - Captain Frezier was returning from Chile to his homeland, and as a curious person, he took with him a souvenir - 5 interesting bushes wild plant– Chilean strawberries (Fragaria chiloensis), which had large berries. During the difficult sea voyage, which lasted 6 months, he carefully kept his precious gifts. And when he arrived home, the captain gave them to various people. This was in 1714. One of the bushes then ended up in the Royal Botanical Garden in Paris. Unfortunately, the brought plant turned out to be female and could not bear a single berry... The fact is that Captain Frezier, not being an expert, did not think to take with him a single male plant... and a woman without a man, you know, has no offspring does not give. After the bushes multiplied with tendrils, without ever producing a single berry, they moved to live in Versailles Park, where they were observed by a very famous French botanist. And then a happy coincidence happened, to which we owe the appearance of a new crop - large-fruited strawberries! It so happened that in a neighboring bed another type of strawberry grew - a pleasant-tasting meadow or Virginia strawberry (Fragaria virginiana Duch.), which is also American in origin. The size of the berries of this species is approximately twice as large as that of wild strawberries. By a lucky coincidence, these bushes pollinated with each other, and so the fruit of their love was born. The descendant turned out to be successful, having inherited all the best things: the size of the mother and the taste of the father... In general, a wonderful child was born in nature new hybrid with very tasty and large berries. This created a sensation - all farmers rushed to breed it. Since then, a huge number of varieties of large-fruited garden strawberries have been developed. It turned out that it gave a big head start to strawberries in terms of yield and size. Just like a torpedo next to a jellyfish. What happened to the strawberries? She has nothing to be proud of - strawberries turned out to be uncompetitive - its varieties can be counted on one hand... How to distinguish strawberries from wild strawberries?

In the photo - musky strawberries ( Fragaria moschata) Perhaps the most important difference is that the number of chromosomes in strawberries is three times greater than in wild strawberries! By the way, for this very reason, when crossing strawberries with wild strawberries, useless offspring are obtained. Strawberry is a dioecious plant, dioecious, it has male and female flowers. And accordingly, some plants do not produce berries at all, while others more or less bear fruit. Strawberries produce very low yields, apparently the dioeciousness has an effect. Male strawberry bushes love to multiply, they send out mustaches in all directions, just hold on. Do we need it? There should not be many men in the strawberry patch, otherwise the harvest will be completely reduced. But garden strawberries are mostly monoecious, they have neither male nor female plants– pistils and stamens are located on the same flower. That’s why the yield goes through the roof, and this is the main thing in agriculture. So, now garden strawberries have become friends with the counters of our markets and shops. Okay, even if they incorrectly call it “strawberry” in the old way, everyone is already used to it anyway!

2 The birth of a berry Strawberries come across us everywhere. Cakes, ice cream, canned food, jam, chocolate-covered strawberries - we have many opportunities to enjoy their taste. But, you see, it’s best to grow your own strawberries and eat them in their original form. Strawberries can grow in a small garden, on a personal plot, in a flower bed next to your house. The only problem is choosing the right variety of strawberries, the one that suits your region. And know how to grow it correctly. Those wishing to grow strawberries should know the following aspects: Strawberries are grown in crop rotation after grain crops. It is not recommended to grow it after potatoes or tomatoes. It is impossible to grow strawberries in the same field (place) for several years in a row. Before planting, you need to check the soil and find out if there are cockchafer and wireworm larvae in it. They appear in large numbers if there are forest plantations near your site. It is advisable that you have at least three varieties of strawberries available: early, middle and late. The area for growing strawberries will increase. Strawberries need to be fed: periodically add additional fertilizer - manure and humus.

It is better to plant strawberries in early spring or early autumn. Before planting, plants are kept in a cool place for six or five days. Before planting, the soil must be cleared of weeds and can be treated with herbicides. The first two weeks after planting, the soil needs to be moistened. But be careful not to overdo it, otherwise gray rot and gray rot will attack your strawberries. powdery mildew. Growing strawberries can be turned into a highly profitable business. So, strawberries are in great demand in our city markets. But everything depends on the quality of the product. There are not many quality products on the markets, and therefore it is important to keep an eye on this. Strawberry of all garden crops can bring in the most income. Even when growing it using the simplest and most traditional technology, you can get a harvest of up to fifteen tons per hectare. However, it is not necessary to do everything by hand. Most work can be performed using different mechanisms. During the harvest, the main problem is the availability of workers, that is, who will collect the crop. Strawberries have long been a highly profitable business in the United States. Californian farmers are especially fond of its cultivation.

Slide description:

Planting location: Strawberries grow well on a flat surface, on a surface with a slope facing southwest. You cannot grow strawberries on steep slopes, or in low-lying areas where cold air accumulates, which causes the harvest to be delayed and the number of diseases to increase. Unsatisfactory results are also obtained on a steep southern slope, where the snow melts quickly and as a result the strawberries are exposed. Strawberries are moisture-loving, but cannot tolerate waterlogging. The place where strawberries grow must be protected from the winds, since part of the root system freezes at a temperature of 10-12 °C cold, so it is better for it to overwinter under the cover of snow with a layer of at least 20-25 cm. Strawberries cannot be grown for more than 4 years in one place (good 2-3 years), as various infections and fungal diseases accumulate, such as wilta, gray and white rot and other diseases.

Slide description:

Reproduction: Strawberries are propagated by seedlings (rosettes). Seedlings are either bought or grown on their own plantings, which are grown on the shoots (tendrils) of the mother bushes. The best rosettes are those that are located closer to the mother bush. No more than three rosettes are left on the shoot; you can leave up to 5 rosettes, but in this case the last two will be less developed than the first three. Up to 5 shoots are usually left on one mother bush, each with three rosettes. From one bush you get 15 pieces of well-developed rosettes. As rosettes appear on the shoot, they are fixed in wet soil, i.e. small roots go deep into the soil. You can immediately plant the rosettes in small nutrient pots, while the pots are deepened into the soil. It is impossible to grow rosettes and berries on mother bushes at the same time, therefore, the first flower stalks that appear are removed. The best seedlings obtained from bushes in the second year of fruiting. Soils that are slightly acidic are better; loamy and sandy loam containing humus and nutrients are generally suitable. Cold clay soils are not suitable without cultivation. On moist soils with close groundwater, strawberries should be grown in high beds. On sandy soils, strawberries tend to produce low yields with small berries, since there is always a lack of moisture and strawberry plants on these soils feel oppressed. Therefore, the bed for planting strawberries is cultivated 1-2 months before planting.

Slide description:

Landing: Best term planting is summer, from July 20-25. Landing takes place at cloudy weather or in the evening so that the plants can acclimatize overnight. Plant seedlings (rosettes) with 3-4 leaves, a well-developed heart and root system. The seedlings are separated from the mother bush and dug up with a small damp lump of earth and immediately planted in the garden bed. If the seedlings were purchased from outside, they are washed along with the root system in the following solution. Take three tablespoons of table salt and one teaspoon copper sulfate and diluted in 10 liters of water and immersed in this solution for 10-15 minutes. Then they are taken out and rinsed with clean water, and the seedlings will have clean, washed roots. After these treatments, the seedlings are planted in the garden bed. When planting any strawberry seedlings, you must not bury or raise the heart, otherwise in one case it will rot, and in another, naturally, it will dry out. When planting, you need to straighten the roots well, make sure that they do not bend, or pour a mound in the hole and place the seedlings on it, carefully straighten the roots on it and sprinkle it with damp soil. After planting a rosette of strawberries, you immediately need to lightly water it from a small watering can using the sprinkling method. Properly planted seedlings will already form a good bush by winter, which will contribute to normal overwintering. On next year(summer) we get a good harvest from these bushes - strawberries in the first year of fruiting.

Slide 13

Slide description:

For early and mid-early varieties, planting in the first year is done thickened, i.e. between rows 60 cm, in a row 15 cm. With such thick planting in the first year of fruiting, strawberries produce high yield due to thickening. As soon as the last berry picking is over, every second bush is removed, and what remains on the garden bed is bush from bush in a row with a distance of 30 cm. For late varieties, the planting scheme in the first year is 60 cm between rows, in a row - plant from plant 20 cm. After harvesting the first summer harvest, every second harvest is removed, and a plant will remain in the row at a distance of 40 cm. In the first year of fruiting, strawberries give a good harvest due to thickening in the rows. In the second year of fruiting, the strawberry harvest is considered to be the highest and with large berries. In the third year, the yield does not decrease, but the berries are slightly smaller in size. In the fourth year, the harvest decreases and the berries become smaller. Therefore, after the third year of fruiting, the strawberries are removed, i.e. the entire above-ground and root system is dug up and burned.

Remontant strawberries are of particular interest to gardeners. Her main distinctive feature is the ability to lay flower buds at high temperatures and long daylight hours. The harvest continues until late autumn. Berries are formed not only on mother plants, but also on daughter plants. Two types are common in culture remontant strawberries– small-fruited and large-fruited. Small-fruited remontant, bred from the forest, has been known to gardeners since the 16th century. Currently, there are many varieties with berries of varying colors. Some of them form mustaches, others do not. In addition to its nutritional value, remontant strawberries are highly decorative. It is planted along the borders of flower beds, in boxes on balconies.

Slide 17

Slide description:

Large-fruited remontant strawberries have two fruiting periods. It produces the first harvest at the usual time, which coincides with the fruiting of early non-remontant varieties, the second - from August until frost. Flower buds for the second harvest in such varieties are formed during the first flowering, and after the berries are picked, a second abundant flowering begins at the usual time. Varieties of large-fruited remontant strawberries were obtained by selecting clones of non-remontant varieties that tend to bear a second fruit from pineapple strawberries. Research by scientists has shown that the second fruiting is of greatest value, since 80-90% of the berries in one- to two-year-old plants ripen. These dates coincide with the ripening of the most non-remontant varieties. To increase the most valuable second harvest, neglect the first one by removing the flower stalks in May.

4 Beneficial properties of strawberries It replenishes the body with minerals, cleanses it and prevents premature aging. Strawberries are a small but very nutritious, sweet fruit that the earth gives us in the summer. Its name comes from the Latin word “fragaria vesca”, which means “fragrant”, “fragrant”, “fragrant”. Although the flavor of strawberries is a little subdued, they are very tasty and rich in many nutrients. Strawberries were highly valued in ancient times for their medicinal properties. More than 3 centuries ago, the “strawberry treatment” was not the main one for arthritis and gout. Today we love it for its sweet, refined taste, which can be easily combined with various products: yogurt, whipped cream, cakes. It is also an indispensable ingredient in preparing delicious dishes. From a dietary point of view, strawberries are very useful for 3 main reasons: They are very rich in minerals and vitamins, so they are ideal for feeding adults and children. In addition, strawberries are indispensable in the treatment of anemia, a deficiency of vitamins and minerals in the human body. It is considered the main carrier of minerals, as it contains vitamins C and B5, folic acid, iron, magnesium, manganese. It is also rich in potassium, calcium, zinc, phosphorus, copper and silicon.

Strawberries have blood purifying properties. It is used to cleanse the body of toxins, which especially overload the liver and kidneys, as well as in the treatment of obesity and cellulite. Strawberry has alkaline properties in the blood and has diuretic salts such as calcium and potassium, which facilitate the removal of uric acid from the body through the kidneys. Strawberries contain a lot of organic acids: malic, citric, lactic, ethylmethylsalicylic acid, which turns into aspirin, but only in a more natural, digestible form. Acids perform the function of detoxification, which is used in the treatment of rheumatism. Strawberries also help in the treatment of hypertension and are used in medicine as a cleanser for digestive system. Strawberries have antioxidant properties, which prevents cellular aging and promotes healthy well-being. Antioxidants are very important because they protect us from infections and cell death, which in turn leads to cancer. Thus, one of the organic acids in strawberries helps neutralize the cancerous effects caused by tobacco. Undoubtedly, all fruits have antioxidant properties, as they contain vitamins C, E, and beta-carotene, but strawberries are much superior in quality to the fruits we are used to: they are 2 times healthier than plums, oranges and grapes, and 3 times healthier than kiwis. and grapefruit, 6 times - than apple and tomato and 15 times - than pear and melon. 100 grams of strawberries contain: Vitamin C - 5 mg, Vitamin B5 - 0.06 mg, Magnesium - 15 mg, Potassium - 156 mg, Calcium - 24 mg, Iron - 1 mg, Phosphorus - 25 mg.

5 Interesting things about strawberries Strawberries will help to bewitch a man Residents of Japan on average eat 15 million kilograms of strawberries per season. Residents of this country claim that they love this berry not only because of its healing properties, but also because there is an ancient belief that you can bewitch a man with strawberries. Strawberries came to Japan in 1872, and since then more than 100 varieties have been grown in the country. Known for their ingenuity, the Japanese grow apple-sized strawberries, noting that this is not the limit of their capabilities. Experts say that size does not affect the healing and mystical qualities of the berry. Both large and small strawberries alike contain large amounts of vitamin C, a nutrient that helps prevent cardiovascular disease and some tumors. And the Japanese also love this berry for its low fat content and low calorie content, so it is not surprising that strawberries are an integral part Japanese diets. Just like the rose, the strawberry is considered a symbol of love among the Japanese. According to Japanese legend, if you come across a double berry, you need to separate the halves and treat your chosen one to one of them, then mutual love and happiness are guaranteed.

Introduction

A plant with fragrant red berries. What is this? Well, of course, everyone knows the answer - strawberries. This plant has been known for a long time and attracts not only children, but also adults. In winter, you really want aromatic, tasty berries. I decided to try to grow it at home on a windowsill and set myself target:

Do you like eating strawberries?

What are strawberries?

Is it possible to grow strawberries yourself at home?

Have you tried growing strawberries at home in winter?

Want to know interesting facts about strawberries?

Let's get acquainted with the concept of strawberry

Let's look into the encyclopedia and find out that strawberry is a perennial herbaceous plant, a species of the genus Fragaria of the Rosaceae family. Plants of the type Garden strawberry are often mistakenly called strawberries.

It grows wild in Europe; It is also cultivated mainly in Europe (France, Great Britain, Germany, etc.). In terms of productivity, it is inferior to garden strawberries. Demanding on moisture, shade-tolerant. Agricultural technology coincides with the agricultural technology of garden strawberries.

An overgrown juicy receptacle is often incorrectly called a berry - the so-called false berry.

2. Interesting Facts from Internet sources.

a).Historiography of the study of strawberries

I began my work by familiarizing myself with the literature on the study of strawberries. I found that the early history of strawberries 1 supposedly dates back to the Romans and ancient Greeks, although very few records of them survive from that time (since strawberries were not one of the leading crops at that time). Strawberries are found in the medical treatises of Apuleius, in the poems of Ovid and Varro, and in Pliny’s Natural History. It is known that by 1300 strawberries were already cultivated in Europe due to the fact that the French then began to transfer wild strawberries from wild conditions to the garden. At that time, strawberry bushes were regarded more as decorative flowers than as fruits, although the berries were also consumed to a certain extent as food. In 1368, King Charles V even ordered 1,200 strawberry bushes to be planted in his royal garden of the Louvre in Paris.
The British, by the way, were also early admirers of strawberries.
Here is the earliest surviving image of a strawberry, it dates back to 1485 (Mainz Herbarius, “Gart det Gesundheit”) 1: The name “strawberry” comes from the Latin “fragaria vesca”, which means: fragrant or fragrant. Although the aroma of strawberries, in comparison with their sister strawberries, is more restrained, they have no less nutrients and beneficial vitamins. This is a perennial herbaceous plant grown almost everywhere. Strawberries are red, sweet, and have white flesh. Very tasty and nutrient-rich fruits, the medicinal properties of which have been known to us since ancient times. But currently they are used very little.

b). GROWING STRAWBERRY ALL YEAR ROUND AT HOME

To begin with, you will need a room for a plantation (from several square meters ad infinitum), where you could maintain room temperature year-round and where you could install lighting. This could be a non-residential room, veranda, barn, garage, etc.
Strawberries are grown in large plastic bags. The bags are welded from white - to improve lighting - polyethylene film 0.2 mm thick, but you can use another one. Their diameter is 16 cm, length - 200-220 cm (another one is possible, depending on the conditions). The bag is filled with substrate (soil + simple fertilizers), everything is mixed well and poured into the bag. As a more advanced option, you can use a mixture of perlite and peat for the substrate. One end of the bag is sealed. You don’t have to make the bags yourself, but buy ready-made ones. They can be of any size, the only recommendation is a small diameter of the bag, this will make it possible to place more bags in the same area, and will not affect the yield.
Along the bag filled with substrate, landing holes (cuts) are made in a checkerboard pattern, the distance between them is 22-25 cm. The bags are installed directly on the floor. If the bags are of small height and conditions allow, you can make a second tier on top of the lower bags. The upper bags are suspended on additional supports, which must withstand a weight of 30 kg/sq.m (the average weight of one bag with a substrate moistened with water), seedlings are planted in them according to a similar pattern.
Place the bags in rows - on average 3-4 bags per 1 sq.m on each tier. A homemade irrigation system is being built to supply power. Each bag has three tubes: to the top, middle and bottom parts of the bag - on average every 60 cm along its height. The upper ends of the tubes are connected to a distribution pipeline, which is placed above the bags. The volume of the nutrient solution is calculated so that each bag contains about 2 liters of solution.
The main secret of the method is the unique seedling storage technology, which allows you to preserve seedlings in a preserved state for up to 7-10 months. Moreover, seedlings preserved in this way retain their vitality, do not lose their genetic characteristics of the variety, and in the future give stable results in terms of vitality and productivity; they can be planted at any time.
You can even start with a plantation of a few square meters with the most minimal costs, since the materials used for work (plastic bags, fertilizers and minerals, power supply tubes) are available and inexpensive.
From one square meter of area you can get an average of 15-20 kg of berries per turn (2-2.5 months), and having acquired the necessary experience - up to 35-45 kg!!! That is, from 10 sq.m. You will receive at least 150 kg of fresh strawberries per turnover! Moreover, harvests can be harvested throughout the year, on average 5 harvests per year. This means that even in the summer, during the “strawberry season,” you will earn at least $150.

3. Conducted research on growing strawberries at home on a windowsill.

I began my research on October 1, 2012, for this I had to dig up a strawberry bush in the garden and plant it in flower pot.

Introduction

One day my mother brought home beautiful and fragrant strawberries. It was very large, and most importantly very tasty. I asked: “Mom, where did you get this berry?” And she replied: “I grew it in my garden.” Then I thought: “Why don’t I try to grow strawberries myself.”

The purpose of my research: grow strawberries from seeds delicious berry

Object of study: Strawberry seeds

Subject of study: process of germination of a sprout from a seed

Hypothesis: berries can be obtained from seeds grown at home

Tasks:

Collect information about the berry

Learn everything about seed germination

Learn to care for seedlings

Fostering a work culture and a desire to create beauty

Research methods: observation; collecting information from books, magazines, Internet sources; experiment, analysis and generalization of results

The relevance of research: In our village there are 3 garden societies “Rodnichok”, “Romashka”, “Neftyanik”. This is 900 garden plots, which is 3 times less than 3 years ago. Under sanctions, it is very important to have a subsidiary farm where you can get crops, including strawberries. This work also instills a love of work, teaches patience, and allows for the connection between theory and practice and with life.

Chapter 1. Theoretical part

I started my work by studying literature and online sources about strawberries. My grandmother told me a lot.

. Interesting facts about strawberries

(Annex 1)

With proper care, strawberries reward a person with a generous harvest. It can be grown both in a greenhouse and in open ground. And my mother grows strawberries in a pot on the windowsill.

Chapter 2. Practical part

2.1. Sowing seeds

We began our work in January with sowing seeds to obtain seedlings. To do this, I took a dried berry and separated the seeds from the pulp. I filled the pot with soil specially designed for growing strawberry seedlings and moistened it well. Strawberry seeds are small, so very carefully, trying not to lose a single seed, I placed them evenly throughout the pot on top of the soil. To create greenhouse conditions, cover the pot with plastic film and place it in a warm and well-lit place - on the windowsill. The film must be removed only to moisten the soil.

(Appendix 2)

2.2. Seedling care

After 2-3 weeks, the seeds began to germinate. The sprouts are very tender and fragile. Now you need to ventilate daily, removing the film for 20-30 minutes. The temperature should be around 20 - 21 C°.

In March, although small, but already full-fledged strawberry bushes were formed.

2.3. Dive

When the bushes have formed, the strawberries need to be picked. To do this, you must first water the pot of seedlings so that the soil becomes soft. Fill a separate cup with soil. Then we separate each bush from the pot and plant it in a separate glass. The ground should not cover the outlet. Let's water the bushes and put them in a well-lit place again.

2.4. Planting in open ground

In May, strawberries can be planted in open ground. It is recommended to plant on an area with a flat surface. Before planting, the soil must be fertilized with rotted manure. We dig a hole and plant a strawberry bush in it. The most important thing is that the heart is on the surface of the soil. If it ends up in the soil, the seedlings may rot, and if it is too high, they may dry out. Now the bushes need to be watered abundantly.

(Appendix 5)

2.5. Care and harvesting

Strawberries love moisture, but you can’t overwater them, as they can rot. To prevent this from happening, it is necessary to place dry sawdust or straw under the bushes, then the berries will not lie on the ground and rot. To make the berries larger, you need to remove the whiskers during flowering.

In August, my first berries appeared.
