1. Dredge the channels and drain water in time
After the rain, drain the standing water in the vineyard in time, remove the sludge, and straighten the plants. For vineyards that have been soaked in water for a long time, the main vines can be whitened with 1:10 lime water and wrapped with straw or wheat straw to prevent the bark from cracking due to sun exposure.
2. Plowing in time to improve soil moisture
After flooding, the vineyard soil is easy to compact, causing the root system to be hypoxic. When the soil dries a little, you should hurry up and cultivate it. When cultivating, increase the depth appropriately, mix the soil and mash the soil.
For gardens with long rain soaking time, after draining, the soil around the tree trays should be opened to dry and disperse moisture. After 1-3 fine weather, cover the soil in time to prevent the grape roots from being exposed for a long time.
3. Foliar top dressing
After the grapes are waterlogged, the root system is easily damaged and the ability to absorb fertilizer and water is reduced. It is not suitable to fertilize the roots immediately.
0.1-0.2% potassium dihydrogen phosphate or 0.3% urea solution can be used for foliar top dressing. After the tree's vigor is restored, use decomposed human and animal manure and cake fertilizer to promote new roots.
4. Timely pruning
Cut off broken branches and vines in time to remove fallen leaves, diseased fruits and rotten fruits. For trees with severe root damage, thin branches, cut leaves, and remove fruits in time to reduce transpiration and prevent tree deaths.
5. Prevention and treatment of diseases
After the rain, you can choose fine weather and spray the whole garden with a fungicide to prevent the spread of diseases.
