In the Chaoyang area, annual precipitation is scarce, especially in spring. Precipitation is mainly concentrated in July, August and September. Jujube in the Chaoyang area generally enters the flowering period from late May to early June, and if the climate is dry and rainy during this period, it is easy The formation of “Coke Flower ” off, if encountered more precipitation in particular years, then easily lead to pollination or poor powder caused by the fall.
