How to manage vegetables in the rainy autumn? Vegetable management technology

In the autumn, the rain increases, and the autumn is the rapid growth period of autumn-sown vegetables such as cauliflower, Chinese cabbage and white radish. Continuous rainy days are likely to cause insufficient supply of fertilizer for such vegetables, which causes the de-fertilization condition to affect the growth. How to manage the vegetables in the rainy autumn? Let me introduce you to the vegetable management technology in the autumn and rainy days.

It is recommended that the vegetables be topdressed in time after the weather turns fine. The amount of topdressing depends on the bottom fertilizer or the fertilizer in the field. The application of urea or ternary compound fertilizer is 30-50 kg, preferably using acupoint or ditch. Rainy weather can easily cause diseases to occur after the weather turns fine. Therefore, after the rain stops, it should be sprayed with agricultural streptomycin, chlorothalonil, kelu, and anti-virus cockroaches to prevent soft rot, black rot, downy mildew and black spot. Etc., conditional can be added together with foliar fertilizer (such as potassium dihydrogen phosphate), spray 2-3 times in 7-10 days.

Vegetable management in greenhouses and plastic greenhouses after autumn delay:

Vegetables in greenhouses and plastic greenhouses are expected to have a promising period or a prosperous period.

(1) Melon and solanaceous vegetables: In the rainy days, it is necessary to carry out snoring as little as possible, to work on old leaves, to avoid artificially causing wounds, and to provide an invasive point for the occurrence of diseases.

The preparation method of the drug is: 100-200 times solution of chlorothalonil, 300 times solution of mancozeb or anti-virus cockroach 200-300 times solution.

The shed film should be used to protect the rain and ensure a certain ventilation. It is better to not enter the greenhouse. Conditional can be in the evening, closed shed film, acre with 200-250 grams of bacteriostatic agent or 1 kg of chlorothalonil dust spray to prevent disease. After the weather turns fine, spray mancozeb or chlorothalonil or anti-virus cockroach in time, and mix with sulphonate or pyrimethanil to prevent disease.
