High temperature should prevent kiwifruit sunburn early

The monkey peach fruit is most likely to cause sunburn under high temperature, and early prevention of sunburn is a matter of contention. Several methods of preventing sunburn are introduced: 1. pruning in summer to leave 2-3 leaves on the top fruit, which can shield the direct sun, especially Hayward and Jinxiang. 2. spraying water every few days in the morning and evening if conditions permit, it can also be matched with 400 times of fruit amino acid solution to reduce the orchard temperature and quickly supply nutrients; Third, orchard cover, can be covered with wheat bran or wheat straw, such as Zhangjiang Cheng orchard in Mei County directly covered between rows, reduce soil moisture evaporation; IV, bagging fruit open vent hole, vent hole hours can be slightly cut large, use ventilation, reduce bag temperature, generally can reduce 1-2 degrees Celsius. 5. The kiwifruit orchard without expansion fertilizer should be increased with potassium fertilizer or calcium lactate foliar fertilizer. Calcium can enhance the toughness and cell wall thickness of fruit outer epidermis cells to resist sunburn or damage. VI. Xizhao fruit, hanging grass on the fruit or Xizhao or using newspaper to shade, reducing direct burns of Xizhao fruit. 7. Irrigate in time during drought to reduce the overall orchard temperature and reduce the occurrence of sunburn.
