How to make remedial measures for grapes when hail attacks grape falling flowers and fruits

After the grape was attacked by hail, the branches were broken, the leaves and grapes were damaged, and when serious, the flowers and fruits fell, which not only affected the tree potential and yield, but also caused a high incidence of diseases and insect pests. In order to strengthen the grape management after the hail disaster, ensure the normal growth and development of the grape vine, and minimize the loss, the following remedial measures can be taken in time:

Grape

1. Cut off the grape branches, leaves and seriously injured fruits caused by the hail disaster in time, and remove them from the garden, bury them or burn them. Cut off the broken or split grape shoots and branches in time, cut the wound flat, reduce the wound area, in order to facilitate healing. The grapes seriously injured by hail can be removed seriously. If the injured area is small, the grapes with lesser degree can be retained.

2. Spraying germicidal pesticides to prevent the disease from invading and spreading from the hail wound of grapes. Due to hail attack, new shoots, leaves, branches, fruits and other parts have varying degrees of damage, bacteria are easy to invade. It is suggested that the spray should be carried out by 1000-2000 times of Fumishuang.

3. Topdressing in time. The leaves injured by hail not only hinder the production of nutrients, but also need a lot of nutrition for wound healing. Therefore, the grapes should be replenished with quick-acting fertilizer in time after the disaster. Generally hang fruit grape mu to increase the application of 10kg urea, calcium 20-30kg, potassium sulfate 10kg.

4. Loose soil. After the hail disaster, the soil permeability is poor, the ground temperature is low, and the root growth of grape is affected. It is necessary to plough and loosen the soil in time to increase permeability. Low-lying land, timely drainage, to create a good environment for the root growth of grapes.

5. Strengthen the protection of vines after the disaster. Remove overdense branches and long branches to make the crown ventilated and transparent; remove some weak grape fruits to reduce the load; timely control of diseases and insect pests to create good growth conditions for grapevines.
