Kiwi fruit is native to the sunny slope of the northern foot of Qinling Mountains. It is warm and humid by nature. Its leaves are large and thin. It likes light, but it is afraid of indirect illumination by strong light. Therefore, once the winter temperature is low and accompanied by drought, the leaves will be burned and lead to defoliation. Moreover, the earlier the low temperature season comes, the earlier the defoliation occurs. If the high temperature and drought continue, the leaves of kiwi fruit orchard will often be withered and fallen, especially when the high temperature above 35 ℃ lasts for a long time, the more serious it will be, which will have a serious impact on the tree vigor and yield of kiwi fruit.
