Zhang Zongqin, an associate professor at Northwestern A&F University’s College of Forestry, reminded farmers that the management of grape harvesting aftermath is very important. Management of fertilization and pest control should be done in time to lay a foundation for high production and stable production in the coming year.
Timely clearance of the garden, prevention of disease and insects removal of weeds in the garden, the litter of the orchard and pruned branches and leaves, as well as diseased fruit, diseased ear, diseased leaves and diseased branches that were discarded in the garden after fruit picking, were concentrated in the park. Deeply buried or burned to eliminate the source of pests and diseases. In addition, this year, the grapes were affected by downy mildew, powdery mildew, white rot, and brown spot. Therefore, grape fruits can be sprayed alternately with 50% Ketu WP 500 times, 65% WP WP 500 times, and 70% thiophanate WP 1000 times. Spray once in ten days.
Controlling the leggy branches will consume a large amount of nutrients in the tree body. It should take measures such as topping and wiping off secondary shoots to control its growth, so as to reduce the invalid consumption of nutrients, and promote the growth of the main vines and the retained secondary shoots, and the fullness of the buds. . Can also be sprayed 0.05% than the long-term solution inhibited prosperous, at the same time, should also be reasonable to trim the vines, thick branches to stay, thin branches stay less, over dense branches, thin branches, pests and branches should be removed as soon as possible.
Timely application of post-harvest fertilizer 1 After harvesting grapes, timely spraying foliar fertilizer to restore vigor. Spray a 0.2% urea, 0.1% magnesium sulfate and 0.2% potassium dihydrogen phosphate mixture every 10 days or so. Spray three times. 2 heavy base fertilizer. The basal fertilizer should be re-used before the deciduous leaves of the grapes, soil compost, circling, composting, etc. per acre, human and livestock manure, nitrogen, phosphorus and potassium compound fertilizer, and potassium dihydrogen phosphate.
Timely soil loosening, flood control and drought prevention are the reasons for picking and management. The soil is easy to be practised. Once the fruit is harvested, an cultivator loose soil should be used immediately. Deep plowing soil should be carried out from September to October. Deep plowing can be combined with fertilization. When the rainwater is raining for a long time, it should be drained in time. In case of autumn drought, it should be timely irrigated to maintain the appropriate soil moisture. 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.
Reducing Damage After harvesting some of the growers' grapes, a large number of cut off secondary shoots and old leaves not only affect the ripening of the shoots in the year, but also easily trigger winter buds, seriously affecting the growth and results of the following year's plants. Generally, no picking leaves and less shoots are removed after harvesting. 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.
