Due to the warmer late spring temperatures and unpredictable weather, the grape has suffered from various degrees of frost damage. For the low-temperature climate in this spring, it is recommended to adopt the following technical management measures to reduce losses and increase production and quality.
1. Strengthen soil fertilizer management and restore tree vigor. Timely watering, fertilizing, applying compound fertilizer or organic fertilizer to enhance soil organic matter content, restore the tree vigor as soon as possible. As the grape suffers from freezing injury and reduced absorption capacity, it is particularly important to strengthen the foliar spray and supplement the nutrients. 0.3% to 0.5% urea solution is sprayed in the early stage and 0.3% to 0.5% potassium dihydrogen phosphate solution is sprayed in the later stage. %-0.3% of multi-element compound fertilizer or 0.3% of ferrous sulfate solution is sprayed once a week and sprayed three times.
2. Trim in time to control the load. The pest branch or frozen branches timely cut off, and paint or wax in the wound to prevent injury. The fruit tree should be strictly controlled the load, timely sparse, scaffolding should be controlled within 2000 kg per acre, so that the tree to restore and enhance resistance.
3. Prevent disease early. For plants with severe freezing injury, to prevent the occurrence of root diseases, 800 times of carbendazim or 600 times of thiophanate-methyl or 800 times of virgin mycotoxins can be used to control the roots of grapes.
4. Strengthen summer management. Wipe buds, pick hearts, set tips, tie vines, remove tendrils, and do a good job of summer management.
