Flower and fruit drop of jujube tree and its reason
The number of flowers and fruits in jujube trees accounted for about 98% of the total flowers. Flowers without pollination and fertilization withered and fell off one week after flowering, and there was a second peak after flowering. Jujube fruit yield and termination period varied with varieties. The main cause of physiological fruit drop of jujube is malnutrition. Because the flowering period is in the vigorous growth period of branches and leaves, there is a competition between reproductive organs and the utilization of nutrients. Secondly, the short life span of pollen and the bad climate during flowering are also the factors that cause a large number of flowers and fruits to fall. The effects of diseases and insect pests can also cause falling flowers and fruits.
