Features of planting and growing
Although the cultivation of this variety is largely standard, it is important to observe some nuances.
Preparing for landing
For sowing, use only last year's nigella, otherwise the germination rate will be low. Seedspurchased from the store do not need additional processing.
The site is chosen flat, well lit. The soil is pre-dug, treated with herbicides, and grooves are made.
Important! Onions are not planted in lowlands: having absorbed excess moisture, it will significantly reduce keeping rates.
Ground requirements
Alpha is more demanding on soil composition than most varieties. Prefers slightly alkaline soil. Too acidic earth is alkalized. Dolomite flour is used for liming. If the soil is depleted, organic fertilizers are applied in the fall (10 kg / m2).
Timing, scheme and landing rules
In spring, onions are planted in the first or last days of May, when the soil warms up to + 10 ° C. The scheme is standard: row spacing - 30 cm each, width between plants - 5-10 cm, planting depth - 3-5 cm.
Before winter, the culture is planted in mid-October according to a similar scheme.
Attention! Onions planted in late autumn, before the onset of frost, do not start up arrows and are stored for a long time. In spring sowing, the yield will be higher.
Growing features
For onions to develop properly, the soil must contain nitrogen. If it has not been fertilized since autumn, then in the spring, before sowing, add 30 ml of ammonia to a bucket of water, mix thoroughly and water the soil.
After planting, the beds are mulched and covered with foil for better seed germination. When sprouts appear, the shelter is removed, the soil is sprinkled with sand to preserve heat.
The nuances of care
Onion cultivation is standard: the beds are regularly watered, fertilized, weeded and loosened.
Watering mode
Alpha needs abundant moisture during the growing season: 1-2 buckets of water at room temperature are poured onto each bed. Do this once every 2 days. In rainy weather, do not water the onions, otherwise the bulbs will rot. Irrigation is stopped before harvesting.
Loosening and weeding
To prevent the formation of an earth crust and provide access to oxygen, the soil is loosened every 2 weeks after germination. Together with loosening, weeding is carried out, since weeds grow faster than onions and take away nutrients from it.
Top dressing
2 weeks after the first shoots, the culture is fertilized with a mixture of minerals (40 superphosphate, 30 g of ammonium nitrate, 20 g of potassium chloride per 10 l of water). For each 1 m2 spend 1-2 liters of funds.
Summer residents often use herbal infusion: about 1 kg of cut grass is poured with a bucket of water, infused for a week, diluted in half, add 1 tbsp. wood ash.
As an organic feeding, a solution of chicken manure (1:20) is used, which is infused for 10-14 days. After that, it is again diluted with water 15–20 times and the onion is poured under the root.
Disease and pest control
If the rules of care are not followed, the onion is exposed to diseases and attacks of pests:
- Onion flies... Insects are scared off by the smells of carrots, tomatoes, parsley. Planting is sprayed with infusions of tobacco dust, wormwood, lemon balm. As a preventive measure, after harvesting, the soil is carefully dug up, and before sowing it is treated with saline.
- Lurkers. The leaves damaged by the beetle are removed. A mixture of tobacco dust and ash (1: 2) is scattered between the rows. For prevention, they observe the rules of crop rotation, destroy plant residues, dig deep into the earth.
- Thrips. Insecticides are used against them, sticky traps are placed between the beds. The row spacings are periodically weeded, for the winter the soil is treated with "Karbofos" (0.15%).
The main illness:
- Peronosporosis. For treatment, seedlings are treated with "Oxyhom", for prevention, the seedlings are warmed up before planting.
- Fusarium. To fight the disease, use "HOM". The planting material is treated with fungicides.
- Gray rot. Limit the introduction of nitrogen fertilizers and increase the dose of phosphorus-potassium.
Harvesting and storage
Ripe onions are identified by the yellowed feathers that lie on the ground and the characteristic color of dry scales.
How and when to collect
The crop is harvested in dry, clear weather before the onset of the first frost, around the end of September or mid-October. The bulbs are placed neatly, dried in the sun. If the vegetables were planted before winter, then they are dug up at the end of spring.
Storage features and keeping quality of the variety
Store the crop in a dark place with sufficient air circulation, low humidity and a temperature of at least + 10 ° C.
Important! Thoroughly dried onions are placed in nets or baskets. In plastic bags, oxygen will not flow to the vegetables, which will lead to rotting of the fruit.
If the harvest has been thoroughly dried, a suitable storage place has been chosen, then the onion will not lose its presentation and taste for 6-9 months.
Growing difficulties
The main problems that vegetable growers face when cultivating Alpha onions:
- yellowing of leaves due to prolonged rains, prolonged drought, temperature changes;
- rotting vegetables with excessive moisture or planting infected seeds;
- change in the color of feathers with a lack of nutrients.
Tips from experienced gardeners
Farmers' recommendations for obtaining a quality crop:
- all formed arrows break off at the root;
- at the very beginning of the growing season, the onions are watered abundantly, gradually the amount of water is reduced;
- harvest before heavy rains so that it is well preserved.
