Cultivation techniques of eggplant throughout the year

Eggplant is an infinite flowering plant, as long as nutrients, water, temperature, light and other conditions can meet its growth needs, eggplant can be cultivated all the year round to harvest fresh fruit. The specific cultivation techniques are as follows:

1. Sowing and raising seedlings should be sowed from November to December of the first year, and greenhouse and middle greenhouse can be used, but the heat preservation conditions should be better. After emergence, the seedlings should grow to the 2-leaf stage to prevent tall seedlings. To pay attention to the prevention and control of diseases, spray 500 times the solution after the emergence of the seedlings, and spray with 40% ethyl phosphine aluminum 200 times 300 times or 75% of the vaccine bacterial clear 600 times after 5 days.

2. Transplanting should be done before and after Qingming Festival, with sufficient base fertilizer and plastic film mulching. In the north, two films are used to prevent frost damage.

3. Cutting stubble will cut off all the main stems and branches of eggplant around the end of July, and the height of stubble is about 15 cm.

4. After field management cutting, deep ploughing, loosening soil and weeding are carried out at a depth of 10m / 15cm to remove sundries and old plastic film, improve the root growth environment and promote the growth of new roots. 3000 kg per mu of human feces and urine, 20 kg of superphosphate and 10 kg of urea were applied deeply between eggplant rows. In case of drought, we should often resist drought and water, maintain enough fertilizer and water to meet the growth needs of new leaves and shoots.

5. The newly growing young leaves and shoots for the control of diseases and insect pests are in the high temperature season in August and are vulnerable to aphids, ladybugs, red spiders and corn borer. Can be used to kill 1000Mel 1500 times liquid, quick kill Ding 1500 times liquid or other high-efficiency and low-toxic pesticide control to reduce pesticide pollution. In case of rainy weather, the occurrence of cotton blight and so on can be sprayed with 400 times liquid and 3000 times ethylphosphine aluminum solution.

6. Reasonable fixed bud because after cutting, there are plenty of fertilizer and water, and more buds grow, and the density control should be reasonable. 5 buds per plant is suitable.

7. Covering film for heat preservation and picking in northern areas should be kept in a shed 5 days before the first frost. Appropriate amount of watering and topdressing, 7.5 kg urea per mu or 100 kg human feces and urine. The fruit is harvested when it grows to a certain size in order to have good quality, high yield and long time. The harvest time can be extended to February of the following year.
