Nearly half a month's weather

First, spraying is not recommended even on cloudy days. If there are pests and diseases, it is recommended to use aerosol.

Second, in the case of cloudy days and sudden sunny days, plants will temporarily lose water or even wither after transpiration increases.

Protected areas can be properly shaded, and the grass curtains can't be opened all at once, but they should be opened after a period of time.

If you find withered, immediately put down the straw curtain to shade. If you have severe wilt, spray warm water on the leaves immediately to relieve it.

Be careful not to use cold water, do not add any pesticide foliar fertilizer regulator and so on. On the first sunny day, the crops were too weak to be sprayed with pesticides or watered.
