When are autumnal aubergines sown? What should I pay attention to when planting?

Eggplant, also known as dwarf melon, white eggplant, hanging vegetable, asparagus, eggplant and purple eggplant, is a kind of vegetable often eaten in daily life and widely cultivated. When will the aubergine be sown in autumn? What should be paid attention to in planting?

When will aubergines be sown in autumn?

The sowing time of eggplant in autumn is from July to August. The suitable sowing time is from July 10 to July 17 when the average temperature is 16-18 ℃, from July 20 to 27 when the average temperature is 18-20 ℃, and from July 30 to August 7 when the average temperature is 2-21 ℃.

What should we pay attention to when planting eggplant in autumn?

1. Water management

Eggplant has strict requirements for water after planting, so water squatting seedlings should be controlled in time to avoid the phenomenon of overgrowth. The time of squatting seedlings was 10ml once every 15 days to promote the root system of eggplant and lay a good foundation for high yield and high yield of eggplant in the later stage. Spraying new high-fat film at the end of squatting seedlings can isolate bacteria infection, improve plant resistance to natural disasters and photosynthetic intensity, and protect eggplant growth.

two。 Fertilization management

Maintaining adequate nutrient supply during eggplant growth is an important prerequisite for ensuring high yield and high yield of eggplant; during the flowering and fruiting period of eggplant in autumn, high quality organic fertilizer or nitrogen, phosphorus and potassium mixed fertilizer must be applied to the roots every 10 to 15 days. Vegetable fruit Zhuangtieling is sprayed before flowering, young fruit stage and expansion stage of eggplant, so as to improve plant water absorption and fertilizer absorption, promote eggplant cyclic fruit setting rate, rapid fruit development, high yield, stable yield and high quality.

3. Seedling stage management

The seedlings were carried out for 2-3 times in the seedling stage, and the overdense and weak seedlings were removed. The seedling period is in the rainy season, with high humidity, so we should pay special attention to prevent sudden fall disease and blight disease, and water less. Immediately after the occurrence of the disease, pull out the diseased seedlings and sprinkle appropriate amount of plant ash to control the spread. In addition, avoid retting roots and overgrowing seedlings. According to the growth of seedlings, light mature human feces and urine were applied 1-2 times. The seedlings were 35-40 days old and planted in sunny evening or cloudy days.

4. Pest control

Eggplant is most vulnerable to tea yellow mites, stem borer, aphids, whitefly, anthracnose, cotton rot and gray mold during the period of high temperature and drought in autumn, which causes a large number of flowers and fruits and causes fruit deformities, which seriously affects the yield and quality of eggplant. According to the law of the occurrence of diseases and insect pests, field management should use targeted chemicals to prevent and control the occurrence of diseases and insect pests in time, which can be mixed with photosynthetic nutrient film fertilizer to help plants absorb light energy, improve fertilizer efficiency, enhance vitality and thrive.

In addition, before planting, it is best to choose varieties with marketable, high quality and high yield, which are more resistant to cotton blight, brown stripe and Verticillium wilt.
