First, repair rain shelter
It is difficult to repair the vineyard shelters as soon as possible.
1, only the damage to the greenhouse membrane, it should be the best treatment, re-cover the greenhouse film;
2. Vineyards with damaged greenhouse membranes and steel pipes, etc., should be repaired or replaced with steel pipes, and then re-covered with greenhouse membranes;
3. For damaged vineyards such as greenhouse membranes, steel pipes, and cement columns, cement pillars should be replaced or reinforced first, or steel pipes must be replaced or replaced, and then the greenhouse membrane should be covered again.
Second, spray protection
Grapes are sprayed with foliar pesticides such as Dasheng and Shijiale or Suckering or Phoenine to prevent diseases such as gray mold.
Third, branch processing
The new shoots that have been severely damaged and cannot be recovered are promptly cut off. The new shoots left behind will be determined by the number of new shoots and the amount of leaves left by the auxiliary shoots will be determined. For a large number of new shoots, which basically do not affect the yield, the sub tip treatment can be performed according to normal conditions; if the number of new shoots is significantly less, the number of leaves remaining in the shoot should be increased to increase the number of leaves.
Fourth, Baohuabaoguo
For vineyards with more serious damage and fewer inflorescences, the preservation of fruits and flowers can be achieved by spraying flowers with amino acids, fengfeng 481 and other foliar fertilizers. After flowering, red Fuji and other grape inflorescences spray 12.5-15ppm. The glucosinolates (ie, 13 kg to 16 kg of water per Keqi Bao (20% zeomycin)) were used once to increase the fruit set rate of the grapes and the fruit set condition was adjusted after the fruit was set. For the red fruit with high fruit setting rate, the fruit protector may not be sprayed.
Fifth, reinforced shelter from rain
Undamaged or less damaged vineyards should be carefully inspected and the weak links should be reinforced to deal with possible future disasters before they occur.
