Pay attention to these measures after harvesting grapes

First, the leaf control

Leaf protection: Minimize the damage of artificially damaged leaves. After harvesting, the fruits should be minimized or even not used. Avoid burning the burnt leaves caused by high temperature pouring, or apply diammonium on the ground in high temperature weather. After watering, the sun will produce ammonia when it is exposed to the sun, causing damage to the leaves. Prevention and control of downy mildew, black pox disease, brown spot disease, two-leaf spider mites, green blind mites and other late-stage pests and diseases, restore the tree potential, promote the early maturity, prevent premature deciduous leaves.

Controlling the shoots: 1 Take measures such as topping and smearing to control the growth, so as to reduce the inefficient consumption of nutrients, and promote the main vines and the retained secondary shoots to be thick and full, and the buds are full and full. 2 After 15 to 20 days of fruit picking, the branches are reasonably pruned, the thick branches are left, the thin branches are left less, the dense branches, the thin branches, the diseased branches and the early elimination.

The second is cultivating loose soil

After picking the fruit, it should be timely cultivating and weeding, and moderately deep-turning, which is beneficial to the loose and permeable soil, water and fertilizer, and promote new root growth.

The cultivating loose soil should be carried out during the wet period of irrigation or rain, and the soil should be broken to prevent drought in the future. It is important to remember that cultivating loose soil should not be carried out during high temperature and drought periods, otherwise it will aggravate the occurrence of drought.

The third is fertilizer management

Picking fruit fertilizer: The fertilizer can be selected from balanced compound fertilizer + sea spirit bio-stimulant (root type) 300 times liquid. For the more prosperous trees, less or no application is needed to prevent the new shoots from growing and consuming nutrients.

Lower autumn fertilizer: generally completed from late September to early November. At an angle of 70 to 80 cm from the base of the trunk, an annular groove of 40 cm in width and 50 cm in depth is dug outward. Generally, the manure per mu is 2000-3000 kg, and the cake fertilizer is 100-150 kg. After adding 100 kg of superphosphate, it is applied and covered. For the boron-deficient orchard, 0.1 kg of borax can be applied per mu along with the base fertilizer to ensure sufficient supply of nutrients in the autumn tree.

Moisture management: The genus is a shallow-rooted plant, and most of the roots are distributed 10 to 30 cm below the surface of the earth. It is highly vulnerable in the high temperature and drought. During the high temperature and dry season in autumn, the vineyards should be filled with horse water in a timely manner, but not in the high temperature period from 10 am to 6 pm.
