How to grow eggplant and how far away it is?

Sowing time: from July to August in Hunan and from December to February in North China. Timely planting: the suitable planting row spacing is 50 cm and the plant spacing is 40 cm. Temperature management: the suitable temperature is 25-30 ℃ in daytime and 15-20 ℃ at night. Light management: receive sufficient light. Water management: pay attention to drainage and irrigation. Fertilization: rational application of nitrogen fertilizer and potassium fertilizer. Control of diseases and insect pests: the use of wettable powder and trichlorfon and other pesticides.

First, sowing time

1. Autumn sowing is usually carried out in Hunan, that is, from July to August every year, but there are most places where two seasons can be sown alternately, such as North China, which can be sown from December to February of the following year.

2. The temperature of these two periods is generally about 15 ℃, so it is more suitable for the growth of eggplant, and the temperature of flowering and fruiting stage should be about 15-25 ℃. At this time, the eggplant has a good taste and a lot of fruit.

II. Timely colonization

Before planting eggplant, soil preparation can be combined with 5000-6000kg soil fertilizer and 40-50kg compound fertilizer per mu. 7-8 days before planting, the suitable planting row spacing is 50cm, the plant spacing is 40cm, and 3200-3300 plants can be planted per mu.

III. Temperature management

Eggplant likes high temperature, and the suitable temperature for seed germination is 25-30 ℃. The suitable temperature for seedling stage is 25-30 ℃ in daytime and 15-20 ℃ at night. Eggplant generally grows slowly below 15 ℃ and causes flower drop, while when it is lower than 10 ℃, it will lead to metabolic disorder.

IV. Lighting management

Eggplant has high requirements for light time and intensity, generally growing vigorously under the condition of long sunshine and high intensity, good flower bud quality, high fruit yield and better coloring.

5. Water management

Eggplant likes water and is afraid of water, generally in the case of poor soil moisture ventilation, it is easy to rett roots, and high air humidity is prone to diseases, so it is necessary to strengthen water management and pay attention to drainage and irrigation.

VI. Rational fertilization

Eggplant has a very high demand for nitrogen fertilizer, when nitrogen deficiency, flower bud differentiation will be delayed, the number of flowers will be significantly reduced, especially in the peak flowering period, generally under the condition of low level of nitrogen fertilizer, the effect of phosphate fertilizer is not obvious, and the absorption of potassium will increase sharply in the later stage.

VII. Prevention and control of diseases and insect pests

The main results are as follows: 1. The common diseases of eggplant are cotton blight, brown stripe and verticillium wilt. Pulek water agent can be used to control the disease, while copper wettable powder can be used for continuous spraying for 3-4 days.

2. Verticillium wilt can be sprayed with carbendazim or carbendazim with water. Of course, during the growth of eggplant, there will be a lot of insect pests, such as aphids, slugs and vegetable insects. These pests can be sprayed with trichlorfon.
