Cultivation techniques for High yield of eggplant

Eggplant is the main vegetable in the off-season of autumn vegetables, and the harvest in autumn needs to be sown in summer, but in the case of high temperature and rainy summer, eggplant is threatened by high temperature, wind, rain, diseases and insect pests, which will lead to instability of eggplant production. In fact, in the process of planting eggplant, as long as the corresponding management is done, the output can be increased step by step. How to manage the eggplant? How to manage eggplant to achieve high yield? Let's take a look at it.

1. Strong seedling transplanting

The best time to sow eggplant in autumn is from May to June, generally using varieties such as purple eggplant. If you raise seedlings in the open air, you need to start seed soaking and sprouting about a week in advance. Soaking the seeds requires warm water of about 50 degrees, stir in warm water until the water temperature drops to about 30 degrees, and then begin to soak the seeds for 9 hours. After soaking, wrap the seeds in a wet towel and begin to germinate in an environment above 30 degrees. Wash the seeds at least twice a day. Half of the seeds germinate in a week and can be sown. When the seedlings reach 15cm, they have 8-10 leaves, and they can begin to transplant in a month or so. Select strong and good seedlings for planting, the planting density is 50-50cm, it is best to choose around 4 o'clock in the afternoon, after planting will be fully watered, and then irrigated again the next day.

2. Topdressing and watering

After successful colonization, fully mature farm manure should be applied immediately, and the amount of fertilizer should be determined according to the planting area, or a total weight of 20 jin of compound fertilizer should be applied in each hole. Eggplant begins to expand, and when it is in the early stage of expansion, 1450-1550 kg of farm manure or compound fertilizer weighing 30 jin in each hole should be applied. The final result is that 1950-2050 kg of farm fertilizer or 40 jin of compound fertilizer should be applied in the mature stage, and eggplant needs a lot of water, and each stage needs a lot of water, whether in the sepal stage, the bone-strengthening stage or the final harvest period. flush water about 3 days before harvest to facilitate the expansion of the fruit and bright and shiny peel.

3. 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, use the happy pruning method to retain the branches growing on the opposite cross slope or horizontally, and 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 beating the eggplant to the top and picking the heart. This is conducive to the absorption of eggplant nutrients, more conducive to the normal growth and development.

4. Prevention and control of diseases

Summer and autumn happens to be the period of high incidence of diseases and insect pests, at this time to strictly prevent diseases and insect pests, combined with intertillage to weed and cultivate the soil, at least twice intertillage, in order to eliminate weeds. When diseases and insect pests such as cotton blight and eggplant borer are serious, eggplant production will be reduced, or even wiped out, losing commercial value, so a series of agents 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.

The above is how to achieve high-yield eggplant management methods, mainly on eggplant fertilization and pest control should be done in place, as long as these two things are done. It can greatly improve the yield and quality of eggplant, eggplant should pay special attention to diseases and insect pests, because once diseases and insect pests are not properly dealt with, it will lead to eggplant production reduction or even extinction, which will have a great impact on farmers.
