How to replenish calcium in apple trees? When is the best time to supplement calcium to apple trees?

It will also cause a decline in the immunity of fruit trees, vulnerable to a variety of bacteria and disease, so that the quality of fruit will decline, and the yield will be reduced in the coming year. Therefore, the farming network has sorted out two methods of supplying calcium to apple trees, which are listed below for netizens' reference. Methods of calcium supplement for apple trees 1. Spraying calcium fertilizer or topdressing water-soluble calcium fertilizer: Apple trees have the peak period of absorbing calcium twice a year: the first peak period is about 40 days after flowering, that is, the young fruit stage, which can spray high-grade liquid calcium fertilizer on leaves and fruits for 2 times, combined with topdressing high water-soluble calcium when watering for the first time in spring. The peak period of the second calcium absorption is about 40 days before fruit picking. 2 ~ 3 days after bagging, calcium should be sprayed again for 1 or 2 times. In addition, the calcium supplement before harvest is mainly due to the continuous expansion of the fruit body and the corresponding decrease of calcium concentration in the fruit. At this time, calcium supplement can not only significantly improve the firmness of the fruit, but also increase the accumulation of calcium in the tree.
