Beware of premature senescence of eggplant fruit vegetables in summer

The following points should be done to prevent premature aging of summer eggplant vegetables:

???? I. Timely pruning and branching

Due to high temperature in summer, vegetables are easy to flourish, resulting in imbalance between vegetative growth and reproductive growth, which eventually leads to plant abortion after three or four crops of fruit. In order to control plant growth and reduce nutrient consumption, the most direct way is to prune branches in time, and remove old leaves, dead leaves and diseased leaves at the lower part of the plant in time, which can not only reduce nutrient consumption, but also effectively control the spread and spread of diseases, which is conducive to ventilation and light transmission and promote the healthy growth of plants.

? Second, we should keep less fruit and keep fine fruit.

For vegetables in the late stage of growth, we must pay attention to not greedy when leaving fruits, and leave less fruits appropriately. It is advisable to leave 2~3 fruits per ear according to the characteristics of varieties, and the rest should be removed.

???? III. Rational watering and fertilization

Providing sufficient nutrients for plant growth and development is a key measure to prevent plant senescence. The best time for topdressing is after each harvest. In summer, decomposed chicken manure can be applied with watering, mixed with appropriate amount of potassium fertilizer. Can also be used to flush high-potassium compound fertilizer, each time to flush 15 kg per mu is appropriate. Watering should be carried out before 10 a.m. or after 4 p.m., and should not be watered at noon. In addition, attention should be paid to not watering too much, avoid flood irrigation, so as not to cause root injury, leading to premature aging of plants.

???? IV. Early harvest

Early harvest of fruits and vegetables is advocated. Tomato harvest time is the top of the fruit has just turned red, pepper is not red before the green fruit, eggplant is the fruit before the seeds turn brown, the appearance of the variety is oily color, cucumber can be harvested just see the seeds. This reduces nutrient consumption and prevents premature plant senescence.

? V. Prevention and control of diseases and pests

Early blight, late blight, leaf mold of tomato and blight, virus disease and bacterial leaf spot of pepper vegetables are the main diseases that often occur on eggplant vegetables in summer. At the beginning of the disease, tomato early blight can be controlled by spraying with 75% chlorothalonil 600 times solution; tomato late blight and pepper vegetable blight can be controlled by spraying with 72.2% Prolik 600 times solution or 60% Anke manganese zinc wettable powder 600 times solution; tomato leaf mold and pepper vegetable bacterial leaf spot can be controlled by spraying with 47% Garinone; virus disease can be controlled by spraying with virus A500 times solution. Insect pests are mainly used to prevent aphids, spider mites, thrips and whiteflies. Insect prevention nets should be set up at the ventilation openings of greenhouses. Insect pests that sneak into greenhouses can be controlled by spraying 3% acetamiprid 1500 times solution mixed with 25% buprofezin solution. When there are spider mites, 1.8% abamectin 2000 times solution can be mixed for control.
