Abstract: In meteorology, the daily maximum temperature reaching or exceeding 35 ℃ is called high temperature weather. High temperature weather has a great impact on the growth of grapes. It not only causes the leaves or branches of grapes to burn, scorch,wither and fall off, but also inhibits the normal growth of grapes. The damage to the flowering period is more serious, which can significantly reduce the yield and quality of grapes. Therefore, we must pay attention to and slow down the harm of high temperature to grapes, so as to improve the economic benefits of planting grapes.
