What is a bow
Onions are a genus of biennial and perennial plants of the Amaryllis family.... All species are herbaceous, have a sharp, specific odor. In cooking, both the stems and the bulbs themselves are used.
Among the species there are also those that grown for greens:
- speed (chives);
- leek;
- slime (drooping onion);
- batun;
- shallot.
Varieties and hybrids suitable for long-term storage are valued for keeping quality, medium and large bulbs, their taste. Consumers love vegetables that are sweet and tear-free when peeled and chopped:
Origin and development
People began to cultivate onions 4-5 thousand years BC on the territory of Asian countries: modern Afghanistan and Iran. Onions became the first cultivated plant.
The vegetable was consumed in ancient India, Greece and Egypt. There, the plant was also credited with magical significance: it was believed that it gives strength and courage.
In Western Europe, the vegetable appeared in the 5th-6th centuries AD. e. In Russia later - in the XII-XIII centuries.
Due to the cold resistance of the culture, it is grown both in subtropical climates and in northern latitudes.... Onions grow and develop at temperatures of + 3 ... + 5 ° C.
Chemical composition
Onions contain a lot of substances useful for humans.... Sugars are represented by glucose, sucrose, fructose and maltose. The vegetable contains 10-11% of them. This means that in terms of the amount of sugars, a spicy vegetable is not inferior to a sweet pear.
Plant contains citric and malic acids, inulin polysaccharide, fats, phytoncides, an essential oil with disulfide, which provides the characteristic pungent odor.

The vegetable activates the processes of hematopoiesis, normalizes water-salt metabolism in the body, lowers blood sugar.
Varieties

Onion
Onions are a perennial plant with a fleshy round or slightly flattened bulb (turnip). Depending on the variety, the colors of dry scales and pulp differ (there are white, yellow, purple shades).
The culture gives a marketable turnip in the second year after sowing nigella... In the first year, a small set grows, which is planted to obtain large, select onions.
In the northern regions of Russia, the duration of vegetable cultivation is delayed up to three years: due to the harsh climate, the crop does not have time to ripen to a presentation in two years.

Which variety is healthier for the body
The benefits of onions for humans are enormous., but it cannot be argued that red is more useful than white, or vice versa. It all depends on the health problem or prevention goals.
Any variety of culture has a powerful antimicrobial effect due to the presence of phytoncides. Purple and red vegetables are more active in the fight against pathogenic microflora, since, in addition to phytoncides, they contain cyanidin.
If a person's task is to stop the harmful activity of microorganisms, then white onions will suffice, but if it is also required to strengthen the circulatory system, then a red or purple vegetable will help.
The plant has anthelmintic properties... White turnips are more effective in combating freckles and pigmentation.
To strengthen immunity and replenish vitamins after winter, varieties of green onions are suitable.
Planting and growing different types of onions
There is no fundamental difference in the cultivation of different plant species... The main thing is to observe crop rotation rules: no related crops (other varieties or bulbous) should be the predecessors in the garden. Otherwise, vegetables will start to rot, various diseases will "cling" to the plant.
When planting onions, they monitor the timing and composition of the soil: sowing too early, high soil acidity, deficiency or excess of nitrogen will not allow the plant to develop normally.
The place for culture is chosen sunny, warm - the juiciness of vegetables and greens depends on it.
Important! Loose nutrient soil will protect the plant from rot damage.
The garden is prepared in advance... It is desirable that the predecessors were tomatoes or legumes. Onions grow well after celandine. Experienced gardeners even specially scatter it dried on the ground. The plant disinfects the soil, prevents the spread of diseases and pests.
The acidity of the soil should be neutral. The bed is fertilized with organic matter or mineral compounds.
How and when to plant
Onions are planted in early spring (on a turnip) and in the fall (on the pen).
Planting sevka:
- Warm up the bulbs if they were stored in a cool place, otherwise you will have to wait a long time for the green arrows.
- Go through the planting material.
- Loosen the bed again, remove weeds.
- Close the sevok to a depth of about 4 cm. The distance between them is 6–10 cm, between the beds - 20–25 cm.
Planting with seeds:
- Scheme - 13x1.5 cm.
- The depth is about 2 cm.
- After sowing, water the beds abundantly.
- Cover the top with plastic wrap to create a greenhouse effect.
Growing technology and care
To protect plants from rotting and diseasesregularly remove weeds and loosen the soil. On average, 1-2 times a week.
For the juiciness of the turnip and green stem the culture is watered once a week. In hot summer - 2-3 times. With long rains, irrigation is temporarily stopped. Some varieties of onions are drought-resistant and do not need additional moisture.
So that the onions quickly go into greens, it is fed with 1 tbsp. mullein, 15 g of urea, diluted in one bucket of water.
Reference. From the fungus, the culture is treated with a solution of copper sulfate. They do this when the stem reaches 15 cm. Some gardeners add crushed laundry soap to the solution.
Which varieties to choose depending on the time and region of planting
Despite the unpretentiousness and frost resistance of the plant, it is advisable to choose those varieties and hybrids that are suitable for a particular region... See the table for details.

It is better to plant varieties before winter Arzamas, Danilovsky 301, Stuttgarter Riesen, Strigunovsky, Goldfish, Chalcedony.
For spring sowing in the middle lane fit Sturon, Centurion and Hercules.
Long-term storage varieties
The best keeping quality is for onions with a golden color of dry scales... Such vegetables have a bitter taste, a pungent smell, but they are stored almost until the new harvest due to the thickness and number of outer scales. Sweet varieties have few scales, they are too thin, so the keeping quality of the crop is low.
Important! According to summer residents, sweet colored onions (red, purple) quickly lose their presentation and taste.
How to store correctly
Fully ripe dry specimens are selected for storage., if necessary, they are dried several times.
The wintering room must be dry and cool (temperature - 0 ° C). Some species thrive well at -3 ° C, and some - at + 18 ° C. It is not recommended to put baskets with crops on the balcony: the vegetable does not withstand temperature changes.
They keep the harvest in a "breathing" container in winter: boxes, baskets, mesh bags. Some housewives, observing tradition, knit the bulbs into wreaths and weave them into "braids".
Conclusion
When growing this crop, attention is paid to the description of a specific onion variety, its keeping quality, presentation and taste, regions for which it is recommended. Although this plant is unpretentious to maintain and resistant to adverse weather conditions, it is important to follow standard agronomic standards to obtain a rich harvest.
