Eggplant is not suitable for continuous cropping with other eggplant vegetables such as tomatoes, potatoes and peppers. , so as not to be infected with soil-borne diseases, such as Ralstonia solanacearum and Ralstonia solanacearum. Eggplant is the main vegetable in summer, and the following links should be paid attention to in eggplant planting management:

1. Seeding and seedling raising of eggplant

Is eggplant suitable for 25? When the temperature is high at 30℃, the overwintering seedlings of spring eggplant should be planted from the end of1October to the middle of1month in the previous year, and winter planting should not be too early. They should be planted in the field when the outdoor temperature is stable above 10℃. Planting 2000-2200 plants per mu and close planting can increase early yield.

The growth period of Kandelia candel is short, so it is advisable to sow and raise seedlings in June, so that the flowering and fruiting period is 9? In the warm season of 65438+ October. 2200-2500 plants can be planted per mu.

Second, fertilization management of eggplant

Applying more nitrogen fertilizer during flowering and fruiting period has a great effect on increasing the yield of eggplant, and there is little phenomenon of excessive growth. Generally, 30 ~ 50 loads of decomposed manure are used for each mu of base fertilizer, 50 kg of calcium superphosphate is applied, and human manure or chemical fertilizer is used for topdressing. Top dressing every ten days. Results The peak period is the period when fertilizer is most needed, and urea or total fertilizer can be dug between two plants.

Water is needed less before fruiting, but most when fruit is expanded. But in poorly drained clay, tomato roots are easy to rot.

Eggplants that bloom before the end of April (the lowest temperature at night is below 15℃) are easy to drop flowers. Use 2,4-D20? Spraying flowers with 30ppm or 25-40ppm anti-falling liquid can prevent falling flowers and mature early.

Third, if necessary, the eggplant should be pulled out completely.

The branch growth and flowering and fruiting habits of eggplant are quite regular. Pruning is generally not allowed. Instead, cut off a few lateral controls with dense branches near the root under the first flower to avoid excessive branches and poor ventilation. However, 1-2 branches can be left in the lower axil of the first flower in the trunk to increase the leaf area and the number of fruits.

Eggplant grows strongly, with many lateral branches and fast leaves. Especially in the case of suitable temperature and sufficient fertilizer, branches and leaves grow too densely, which will form rotten fruits and poor fruit color. Therefore, it is necessary to properly pick out too dense leaves, diseased leaves and some healthy leaves to facilitate ventilation and light transmission. You should pick leaves many times during the whole growing period, so you don't have to pick too many leaves at once.
