Grapes must be strengthened after picking
First, the practice of increasing fertilization materials shows that the application of basal fertilization in the autumn is getting as early as possible. Under normal circumstances, 2000 kg of organic manure, circulatory fertilizer, compost, and other organic fertilizers are added to 20 kg of superphosphate 20 kg after mixing. After the application, cover the drenching water.
Second, inhibition of shoots and vines will lead to depletion of nutrients in the tree body. Take measures such as topping and wiping off secondary shoots to control their growth so as to reduce the inefficient consumption of nutrients and promote the growth of the main vine and the retained secondary shoots. Full and full. At the same time, the branches should be properly pruned, stout branches to stay, thin branches stay less, over dense branches, thin branches, pests and branches should be removed as soon as possible.
Third, the cultivating loose soil in autumn orchards, poor soil permeability, therefore, timely picking and weeding after fruit-picking, and deep-turning, this is not only conducive to loose soil in the garden and can maintain water and fertilizer, promote the growth of new shoots .
Fourth, disease prevention and disease removal of grape leaves susceptible to downy mildew, powdery mildew, white rot, brown spot damage. Therefore, the grape fruit can be sprayed with 70% thiophanate-methyl wettable powder 1000 times, and sprayed once every 10 days.
V. Reducing damage In some areas, after harvesting grapes, a large number of off-shoots and old leaves are cut off, which not only affects the ripeness of the branches in the year, but also easily triggers winter buds, seriously affecting the growth and results of the plants in the following year. Generally, the leaves are not picked after harvest and the shoots are not removed. Try to keep strong foliage. At the same time, mechanical damage to the branches and leaves is prevented during field operations to ensure that the branches are normally mature.
6. Arrange the orchards for frequent operations such as picking and management, and the soil is easy to be practical. Immediately after fruit picking, a cultivator ripping should be performed to increase the loose air permeability of the soil and promote new roots. Combined with autumn and winter pruning, the litter and pests in the orchard will be completely removed and destroyed in a centralized manner, reducing the number of disease and insects overwintering bases, and reducing the damage of pests and diseases in the following year.
