Year-round cultivation techniques of eggplant
Eggplant is an infinite flowering plant. As long as nutrients, water, temperature, light and other conditions can meet its growth needs, it can be cultivated all year round and harvest fresh fruit. The specific techniques for cultivation are:
1. Sowing and seedlings should be planted in the first 11-December of the year, and can be used in greenhouses and sheds, but the insulation conditions should be good. After emergence, the seedlings should be grown until the 2 leaf stage to prevent high seedlings. It is necessary to pay attention to the prevention and treatment of diseases. After the emergence of the seedlings, it can be sprayed with 500 times of liquid medicine, and after 5 days, it is sprayed with 40% of ethyl phosphine bromide 200-300 times or 75% of bacteriophage.
2, transplanting should be transplanted before and after the Qingming, and apply the base fertilizer, covered with plastic film. The north is covered with two membranes to prevent frost damage.
3. Cut the branches and leave the main stems and branches of the eggplants around the end of July, leaving the height of about 15 cm.
4. After field management, cut the branches and carry out deep weeding and weeding, the depth is 10-15 cm, remove debris, old mulch, improve root growth environment and promote new root growth. Acre of manure urine 3000 kg, 20 kg of superphosphate, 10 kg of urea, deep application in the eggplant line. In the case of drought, it should always be water-resistant and maintain sufficient fertilizer to meet the growth needs of new leaves and shoots.
5. Controlling the new growth of young leaves and shoots of pests and diseases, in the hot season in August, vulnerable to aphids, ladybugs, red spiders and corn borers, it is necessary to timely control drugs. It can kill 1000-1500 times of liquid by enemy, fast killing 1500 times liquid or other high-efficiency and low-toxic pesticides to reduce pesticide pollution. In case of rainy weather, plague disease can be sprayed with 400 times liquid of phytopathogenic disease and 40 times of ethyl phosphinate aluminum 3000 times.
6, reasonable buds due to cutting, the fertilizer is sufficient, growing more sprouts, density control should be reasonable, each plant 3-5 buds is appropriate.
7. Cover film insulation and picking in the northern area should be shed for 5 days before the first frost. Appropriate amount of water and topdressing, 7.5 kg of urea or 100 kg of human excrement. When the fruit grows to a certain size, it is harvested for good quality, high yield and long time. The harvest time can be extended to February of the following year.
