Of great importance is the processing of bulbs before planting in order to prevent fungal diseases and pest control. Prophylactic treatment and proper landing is the key to high yields.
planting time
Small bulbs are planted in late April, when the soil is warmed up 6-10 cm. It is not recommended to plant in a slightly warmed the earth, or, conversely, to delay the landing. The optimum temperature for the seating of the earth - 12 ° C.
Prepare for landing
An important role for the good harvest plays a proper preparation of seedlings. Initially, onion sets to be sorted by selecting the appropriate size of the bulbs and put in a cardboard box, and then left to warm up the battery, a windowsill or near the gas hob. Used for planting head size of 1-2 cm, since smaller bulbs can not form stems.
Before you plant onion sets, pre-heated it. This is a long process that involves several steps:
- Within 15-20 days, the bulbs are stored at temperatures above 20 ° C.
- Thereafter, for 8-10 hours, heated at a temperature of from 30 ° C to 40 ° C.
Thus onion head warm as the inside, after which they are treated with fertilizers.
If you are unable to perform the heat treatment in stages, before seating, you can pour warm water, but not boiling water. The bulbs in the gauze bag must be placed in the water and hold for 10-15 minutes at a temperature of 45 ° C. It is important that the temperature did not fall below 45 ° C. Then the bulbs were placed in cold water and left for 10-15 minutes.
The heating helps to wake up dormant buds. In addition, it is a good way to deal with pests and diseases. To accelerate the germination and increase the energy for growth, the bulbs are placed in a solution which comprises a mineral fertilizer, and left for 10 hours.
Disinfection
Disinfection is a mandatory procedure, which helps to protect onions from diseases and insects. The bulbs can be affected by thrips, mites, nematodes, molds or rot.
There are several ways to prepare the onion sets for planting:
- Treat pink solution of potassium permanganate, in which the small heads are soaked for 24 hours.
- weak solution of potassium permanganate also used. Process followed for 12 hours.
- To prevent fungal diseases using a solution of copper sulfate: 35 g of fertilizer is dissolved in 10 liters of water.
After processing the onions washed well with running water, dried and prepared for planting.
There is another method for the preparation of small bulbs for planting. They were dried for 7 days at a temperature of 20-25 ° C, and then soaked for 3 h in a solution: 2 tbsp. l. salt in 2 liters. water. After treatment with onion sets must be rinsed, immersed in a dark potassium permanganate solution and leave for 2 h. After this procedure, the bulbs can be planted.
soil preparation
Bow - a photophilous plant, so it is recommended to choose a well-lit area. For planting selected sunny place or penumbra, it is not suitable for plant completely in the shade. Onion is growing rapidly, within 7-20 days will be visible stems. At the beginning of the growth of its watered 1-2 times a week. As maturation requires less water. 2 weeks before harvesting stop watering so the culture is well preserved.
Onions can be planted in autumn or spring in loose fertile soil. Should pay attention to the acidity of the ground level. To reduce the acidity add any fertilizer containing calcium and magnesium. It is not recommended to make organic fertilizer into the soil or humus before planting.
