How to prevent fruit drop in winter jujube in summer? Please guide the prevention and control of fruit drop of winter jujube in summer by the following methods: for the more upright branches, the opening angle of the branches can change the direction, disperse the growth polarity, slow down the vegetative growth momentum, and enhance the ventilation and light transmission of the trees. For the newly germinated useless jujube head, it can be erased from the base when there is no room for development, leaving only 2 or 3 jujube hangers at the base. This can effectively reduce the nutrient consumption of the tree and make the nutrients accumulate on the jujube hanging and the jujube fruit, so as to accelerate the growth of the young fruit and avoid the fruit drop caused by insufficient nutrition. Fertilize jujube trees at flowering stage and after flowering (organic, inorganic and biological ternary fertilizer). A small amount of water can be watered in dry weather, which can obviously improve the quality of leaves, enhance the tree potential and promote the expansion of fruits. Spraying foliar fertilizer is the fastest and most effective fertilization method for fruit trees, which can increase tree nutrition as quickly as possible to prevent fruit drop caused by high temperature in summer.
