How to manage the high yield of eggplant

Eggplant is a common vegetable in our country, which is grown in many areas, but if we want to have a high yield of eggplant, we need to do a good job in basic management such as water and fertilizer, pest control and so on.

1. Topdressing and watering

After successful planting of eggplant, fully mature farm manure should be applied immediately, and the amount of compound fertilizer should be determined according to the planting area or a total weight of 20 jin in each hole. when the eggplant begins to expand in the initial expansion period, 1450-1550 kg of farm manure or 30 jin of compound fertilizer should be applied in each hole, and the final result should be 1950-2050 kg of farm fertilizer or 40 jin of compound fertilizer. And eggplant needs a lot of water at each stage, whether in the sepal stage, the bone-strengthening stage or about 3 days before the final harvest, so that the fruit can be expanded to make the pericarp bright and shiny.

2. Pruning and branching

Eggplant blossom and bear fruit at each stage has a strong regularity, so it is generally necessary to retain the branches of each layer, and use the happy pruning method to keep the branches growing on the cross slope or horizontally to cut off all the rest. After all the young eggplants are seated, they should begin to remove all the buds that come out later, and it is the same after flowering, regularly topping the eggplant and picking the heart. This is beneficial to the nutrient absorption of eggplant and is more conducive to its normal growth and development.

3. Prevention and control of diseases

Summer and autumn happens to be the period of high incidence of diseases and insect pests, at this time, strict prevention of diseases and insect pests, combined with intertillage to weed the soil, at least twice intertillage in order to eliminate weeds, such as cotton blight and eggplant borer and other diseases and insect pests will lead to a reduction in eggplant production or even the loss of commercial value, so a series of pesticides can be used to prevent and treat diseases and insect pests However, medication should be stopped a week before harvest to prevent drug residues from causing harm to the human body.
