For the whole jujube planting, the impact is relatively large. This article introduces the common reasons for jujube fruit drop, and hopes to help the majority of jujube growers.
In general, the growth of branches and leaves of jujube trees is synchronized with flower bud differentiation and flowering, and the flower buds are large, the flowering period is long, and the whole plant buds are differentiated for about 2 months. If the nutrition of the fruit trees is not reached at this stage, it is easy to cause Jujube trees appear to fall and fall.

Improper management of water and fertilizer will also cause the fall and fall of jujube trees. Although jujube trees are drought-tolerant plants, new shoot growth and fruit development require more water.

In the flowering period, if there is continuous rain or storm, the flowering rate will increase, leading to an increase in the fruiting rate during the flowering period. In the fruit growth period, in the event of natural disasters such as strong winds and hail, it will also cause fruit drop.
