How to manage pomegranate trees in summer? Please give an introduction
Pomegranate tree summer management mainly consists of the following three major points:
Fertilization For young pomegranate trees that have not yet reached full growth, apply fertilizer once after 2/3 of the flowers have dropped and once about 1 month before the fruit ripens; for mature, high-yielding large trees, in addition to the above two fertilizations, at the early stage of bud break and flower bud appearance, one additional fertilization is needed. In the early stage, nitrogen fertilizer and phosphorus fertilizer are mainly applied; in the later stage, potassium fertilizer is mainly applied. The amount of fertilizer applied should be determined according to the fruit yield; trees with fewer fruits can be given less fertilizer, and vice versa more.
Pruning The pomegranate tree is a tree species that greatly loves light. The distribution of branches within the canopy should be sparse at the top and dense at the bottom, so that both inside and outside can have ventilation and light for fruiting. On the basis of shaping and pruning in winter and spring, in summer pinching should be carried out, vigorous shoots should be cut back or their tender tips removed, and attention should be paid to removing sprouting buds to reduce their competition with branches for nutrients.
Disease control The diseases harming pomegranate trees are mainly dry rot and early defoliation disease. If disease is found in summer and autumn, Bordeaux mixture can be used for control before flowering, and thiophanate-methyl solution can be used for control during the flowering period. After fruit set and during the young fruit enlargement stage, spraying with dufulin or tuijunte, etc. can be used for control, spraying once every 7-10 days, several times in succession, and stopping medication one month before fruit harvest. In addition, bagging pomegranate fruits during the young fruit stage can reduce the severity of damage from diseases such as pomegranate dry rot.
