First, control the dendrite
After the fruit is harvested, the continuous growth of the grape dendron will consume nutrients from the tree body. In addition to taking measures such as topping and removing auxiliary shoots to control its growth, 0.05% of the long-term solution may be sprayed to suppress its growth and reduce the consumption of nutrients.
Second, fertilization
The results of grape tree body consumption of a large number of nutrients in the body, the fruit must be sprayed after the timely application of foliar fertilizer to restore vigor, enhance leaf photosynthesis ability, spray once every 10 days once 0.2% of urea and 0.2% dipotassium phosphate mixed Liquid, even spray 2 to 3 times. In addition, it is also necessary to apply basal fertilizer in autumn, use 2000 tons of organic fertilizer, soil fertilizer, compost and other organic fertilizers per acre, and add 20 kg of superphosphate to mix it and then apply it into the trenches. The amount of fertilizer can be determined according to the current year's yield combined with the tree vigor. The yield is high, tree vigor vineyards apply 30 to 40 kg of compound fertilizer per acre, and vineyards with average yield and weak tree vigor have 40 to 40 kg of compound fertilizer per acre. 50 kilograms.
Third, inhibition of dendrite
To deal with vines to 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.
Fourth, the cultivator loose soil
The autumn orchards are overgrown with weeds and have poor soil permeability. Therefore, timely cultivating and weeding after fruit-picking and deep-turning are beneficial to the loose air, water, fertilizer, and new shoot growth.
Fifth, disease prevention and disease
Grape leaves are vulnerable to downy mildew, powdery mildew, white rot, and brown spot disease. Therefore, grape fruits can be sprayed alternately with 50% Ketu WP 500 times, 65% WP WP 500 times, and 70% thiophanate WP 1000 times. Sprayed 10 times a day.
Sixth, reduce damage
In some places, after the harvesting of grapes, a large number of offshoots 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 cutting, and the shoots are rarely removed. branches and leaves. At the same time, mechanical damage to the branches and leaves is prevented during field operations to ensure that the branches are normally mature.
VII. Ordination
Due to frequent picking and management operations, the soil is easy to be practised, and once cultivated, a cultivator ripping should be performed immediately to increase the loose air permeability of the soil and promote new roots. It is also necessary to combine autumn and winter pruning to better organize the orchard.
