Landing dates
The timing of planting this crop depends on the cultivation method and the region. If you plant seeds for seedlings, the optimal time is from the end of March to the first ten days of April, since the Olin onion belongs to the early ripening ones. In this case, the seedlings are transferred to the ground at the beginning of May, i.e. about two months after germination. Also, seeds can be planted in open ground - it is advisable to do this at the end of April. Sevok is planted around the same time.
Autumn planting is also allowed. To do this, use sevok, which is planted:
- from late October to early November in Central Russia;
- from the last days of September to mid-October in the Urals, Siberia, the Far East.
To harvest a large harvest, Olin onions are recommended to be planted just before winter. Otherwise, the indicators will be low.
Olin onion planting methods
Olin onions can be grown in the following ways:
- sowing seeds for seedlings or in the ground (annual crop);
- sowing on the bed (for biennial specimens).
The easiest way is to plant a set and get a harvest in July. The seedling method of growing Olin onions is also allowed. It is more laborious, but more economical in terms of costs.
Growing seedlings from seeds
At the first stage, the seeds of Olin onions need to be prepared for planting. They are pickled in a weak solution of potassium permanganate for half an hour. Placed in warm water, then allow to dry and incubate in "Heteroauxin" or other growth stimulant. After that, it is wrapped in damp gauze, put in a saucer and kept at room temperature for a week.
Olin's onion seedlings are grown in low boxes
Then they act like this:
- They take a soil mixture prepared in advance (two parts of sod land and one part of black peat, humus and sand).
- Previously, the earth is placed in the freezer for several days or kept in the oven (15 minutes at 130 degrees).
- The soil is placed in individual pots or common boxes up to 10 cm high. You can use cassettes. In this case, 3-4 seeds are sown in each cell.
- Grooves are made at a distance of 5 cm.
- Spread Olin onion seeds with tweezers to a depth of 0.5-1 cm with an interval of 3 cm.
- Sprinkle with soil, spray a little with water.
- Cover the container with plastic wrap, periodically ventilate and watered. Maintain the temperature at + 22-25 degrees.
- When shoots appear, the film is removed. The temperature is lowered to + 15-18 degrees.
- Two weeks before the transplant, the containers are taken out onto the balcony or outside, tempered at a temperature of +10 ° C.
- They are transplanted into open ground closer to the beginning of May. The planting depth is 2 cm, the spacing is 6 cm, the distance between the furrows is 50 cm. At the time of transplanting, each seedling should have at least three full-fledged leaves. Previously, the roots of the seedlings can be held in a growth stimulant solution.
- During transplantation, the leaves and root processes should be shortened by one third of their length.
Planting sevka in spring
Olin onion sets are sown in spring at the end of April (if the weather is warm and dry). The algorithm of actions is as follows:
- Clean, dig up and fertilize the soil in advance, for example, with compost or humus (5 kg per 1 m2).
- Select sevok - it should be moderately large (up to 3 cm in diameter) and without rot, damage. Two weeks before planting, warm up for six hours at a temperature of 40 degrees, then pickle in a fungicide for 0.5-1 hours.
- Make several furrows at a distance of 25 cm.
- Plant the seedlings to a depth of 1.5 cm at intervals of 5 cm (for large bulbs, the distance is 10 cm).
- Sprinkle with fertile soil and water abundantly.
- Place sawdust, straw, needles or other mulch 3 cm high.
Olin's onion care
When planting seedlings, the first shoots appear after 10-15 days. To do this, it is necessary to ensure normal watering, feeding and other conditions:
- Water the onion as the surface layer of the soil dries out. In a drought, water is given at least once a week. At the same time, a month before harvesting, watering is stopped, even if the heat is established.
- Top dressing is applied three times per season - after the appearance of green feathers, urea is given (20 g per 1 m2), after three weeks superphosphate is given (20 g per 1 m2) and potassium salt (10 g per 1 m2), after another 21 days, the same composition is introduced.
- After watering and rains, the soil should be loosened.
- Weeding is done regularly to prevent weeds from germinating. To make the task easier, it is recommended to lay out a layer of mulch.
Disease and pest control
Olin onions are generally resistant to various diseases and pests, but they can suffer from onion flies, and with excessive watering, from root rot. Powdery mildew damage is also possible. The main preventive measures are:
- moderate watering;
- regular loosening of the soil and weeding;
- inspection of crops and processing by various means.
If a whitish plaque, spots and other signs of planting are found, they are treated with Bordeaux liquid or fungcides ("HOM", "Skor", "Ordan", "Fitosporin"). To combat the onion fly, folk remedies are used:
- dusting with tobacco dust or wood ash;
- spraying with a solution of laundry soap or salt;
For prevention, treatment with infusion of dandelion leaves is necessary.
If these measures do not help, apply insecticides:
