If the management of grape harvesting is relaxed, it will inevitably result in serious diseases, early defoliation, immature branches, weakened tree vigor and so on, affecting the grape's output and quality next year. Autumn is a golden period for the vine to recover its "strength" and must therefore be strengthened. First, pick up the heart in time to the auxiliary tip. After entering the autumn, all the tip of the whole grape plant will be picked up, and all the branches will leave one leaf to pick it up. To the old leaves, the leaves of the grapes were determined to grow organically when grown to the size of an adult's palm. The leaves after aging should be removed in time to reduce nutrient consumption and improve ventilation and light transmission conditions, which is conducive to plant growth. Second, disease prevention leaves. During this period of autumn and winter, the autumn season, the chance of grape disease is much lower than in summer. But sometimes it is still hot and humid. Downy mildew, blackpox, etc. will still occur in large areas and must not be taken lightly. It is mainly prevention. The prevention and control measures may be followed by spraying a broad-spectrum bactericidal drug once in the clear garden. After 7-10 days, it will spray 180 times more Bordeaux waves. After treatment according to the above method, as the weather becomes more and more cool, generally no more disease will occur in a large area. However, it should be observed from time to time, see the initial disease, immediately symptomatic medication. Prevention and treatment of diseases can protect the leaves, promote shoot ripening and flower bud differentiation, and it is a key aspect of high yield in the coming year. At this time, individual plants may have white rot and mantle disease. The disease occurs at the base of the new shoot. The upper part of the shoot is still growing. It should be cut off from the base and cleared out of the park. Don't be a pity that these kinds of species leave the source of disease. In addition, autumn is the peak period of downy mildew, blackpox, and brown spot. It should be used 500-600 times of metalaxyl, 350-400 times more kill, 400 times more chlorothalonil, etc. . Third, moderate security. Grapes are more resistant to drought. If the weather is not very dry during this period, water is not needed. Only the cultivator can be kept. If it is very dry, water it again. After the topsoil is loosened, it will be protected by cultivators. At this time, heavy rain will continue to fall in some areas. Pay attention to drainage, and if the surface soil is loose, it should be protected by cultivators. Fourth, rational fertilization. Fertilizer is applied when the leaves are wilting in the late autumn and early winter, and the decomposed farmyard fertilizer is the main fertilizer, supplemented by chemical fertilizers. Generally, 3000-4000 kg of organic fertilizer, 10-15 kg of potassium chloride and 30-40 kg of superphosphate are applied per acre to increase tree vigor. Fifth, clear the garden. Many diseases and pests of grapes will winter as the branches and leaves in the ground. Therefore, after the fall of the grapes in autumn and winter, the fruit growers must seize the time to conduct an orchard disinfection and clearing the garden. The specific method is to cut all the residual leaves and stubs of the vineyard ground after the pruning of the whole park and then burn them together. The entire park is sprayed with 3-5 degrees lime sulfur and the entire garden is deep-turned to destroy the pests' wintering sites and reduce the number of pests and diseases. Wintering. And to sort out the trenches in the field to prevent waterlogging. 2L-size Carrot,2L-size Fresh Carrot,Fresh Carrot Size 2L,2L-size Red Color Carrot Yirun Agricultural Cooperative , https://www.yiruncn.com
