How to carefully manage the grapes after harvest

1. Controlling the branches and vines. After the fruit is harvested, the vines and vines will continue to grow, which will consume the nutrients of the tree. In addition to taking measures such as topping and removing the secondary shoots to control their growth, spraying foliar fertilizers should promote the nutrient return of the top tips of the plants and inhibit the main shoots. Prosperous.

2. After adding fertilizer to the vine body, a lot of nutrients are consumed in the body. After picking the fruit, it is necessary to spray foliar fertilizer in time to restore the tree vigor and enhance the photosynthesis ability of the leaves. Spray 0.2% urea and 0.2% every 10 days or so. % Dipotassium phosphate mixture, spray 2-3 times in a row, and at the same time spray 800 times the new high-fat film to increase the utilization rate of the effective ingredients in the fertilizer. In addition, it is necessary to apply basal fertilizer once in autumn. Use more than 2,000 kg of organic fertilizers such as soil, manure, and compost per acre, add 20 kg of superphosphate and mix it in the ditch. After the application, cover the soil and spray the tree guard to sterilize and disinfect. Reduce the source of germs.

3. Controlling pests. Grape leaves are vulnerable to downy mildew, powdery mildew, white rot, brown spot and other diseases. If the control is not effective, it will wither and fall off prematurely, affecting the accumulation of nutrients. Therefore, we must continue to do a good job in the prevention and treatment of these diseases after the grapes are picked. You can choose 200 times and a half volume Bordeaux liquid, 70% thiophanate methyl wettable powder 1000 times liquid, etc. alternately spraying, and spraying with the new high-lipid film 800 times liquid to increase the effective rate of the effective ingredients of the drug and consolidate the control effect. Spray once every 10-15 days.

4. In autumn orchard with loose soil, weeds grow thickly and the soil has poor air permeability. Therefore, after picking the fruit, it should be cultivated and weeded in time, and deep ploughed, which is conducive to the loosening and air permeability of the soil in the orchard, which can retain water and fertilizer, and promote the growth of new roots and shoots. .

5. After cleaning the fallen leaves of the garden grapes, the garden should be cleaned in combination with winter pruning (pruning the mouth and apply the callus anticorrosive film to protect it in time). The litter and leaves should be thoroughly removed and taken out of the garden for centralized destruction or deep burying. The entire garden should be sprayed and protected. General tree sterilization and disinfection to reduce the source of disease. ,
