Apple trees are grown in China. Many people know that when apple trees are deficient in calcium, they will affect the accumulation of sugar in the fruit. The fruit powder is less and the aroma is light. How does the apple tree make up calcium?
Method for calcium supplementation in apple trees 1. Spraying calcium fertilizer or chasing water-soluble calcium fertilizer: Co.,
The apple tree has two peaks of calcium absorption every year: the first peak period is about 40 days after the flowering, that is, the young fruit period, which can spray 2 to 3 times of high-grade liquid calcium fertilizer on the foliage and fruit, and combine Apply high-water-soluble calcium when pouring the first water in spring.
The second peak of calcium absorption is about 40 days before fruit picking. The second to third days after bagging fruit should be sprayed 1 or 2 times. In addition, calcium is added before harvesting, mainly because the causal body is continuously expanding, and the concentration of calcium in the fruit is correspondingly reduced. At this time, calcium supplementation can not only significantly increase the hardness of the fruit, but also increase the accumulation of calcium in the tree.
Apple tree calcium supplementation method II, autumn application of calcium fertilizer:
Autumn application of calcium fertilizer can solve a variety of physiological diseases caused by calcium deficiency in apples. It is best to choose formula fertilization after the fruit is dropped and the base fertilizer is applied before the fall leaves. Try to add a variety of decomposed organic fertilizers. Because organic fertilizers can improve soil, improve soil fertility, increase soil organic matter content, and provide balanced and long-term supply of various nutrients, especially trace elements, to the root growth of apple trees. Fruit coloring and improvement of stress resistance play an important role.
