What are the misunderstandings of apple calcium supplement

Calcium is a necessary medium element in the growth of apples, and it is also very important for the growth of apple trees. If apple trees are deficient in calcium, there will often be a variety of physiological diseases. Thus affecting the growth of apple trees, resulting in the decline of yield and quality. So the work of supplying calcium to apple trees is also very important, but there are often a lot of misunderstandings when replenishing calcium to apples, so what are the specific ones? Let's take a look at it.

1. Only supplement calcium to foliar surface

Many people will only choose to supplement calcium to the foliar surface when taking calcium supplements. In fact, the source of calcium in apple trees is mainly absorbed from the soil through the roots. Foliar calcium supplementation can only play a supplementary role. The content of soil organic matter in many orchards is not very high, plus some of the soil is alkaline. Therefore, the absorption and utilization of calcium in the soil in the root is relatively low. Therefore, when we supplement calcium, we should pay attention to improve the soil matter content and adjust the soil PH value, so as to enhance the calcium absorption capacity of the roots of fruit trees.

2. Calcium supplement in young fruit stage

Many people think that the effect of calcium supplement is the best in the young fruit period of apple trees, and it is useless at other times. In fact, in the whole growth period of apple, foliar calcium supplement can play a role. And the more late the growth, the better its calcium supplement effect will be. Although the young fruit stage because the fruit is smaller, the pericarp is also relatively thin, calcium absorption can be stronger. But it is precisely because the fruit is small, so the contact solution is not much, the amount of calcium supplement will naturally be reduced. However, with the growth of the fruit, the surface area of the fruit will also increase, and the amount of calcium absorption will also increase, so it is best to supplement calcium after bagging the fruit.

3. Calcium amino acid is the best.

Amino acid is a kind of organic compound, which is very beneficial to leaf photosynthesis and allows fruit trees to replenish nitrogen quickly. And if amino acids combine with calcium, they will form a substance of calcium amino acid. Proper spraying on the leaves of apple trees can supplement not only amino acids but also calcium. And the absorption rate of calcium is also higher than that of calcium chloride and calcium nitrate. From this point of view, the effect of calcium supplement should be very good. But in fact, among the calcium supplement preparations of calcium amino acid, the calcium content is generally only about 4%, and it will be even lower after dilution, so the effect of calcium amino acid calcium supplement is not the best.

4. The higher the calcium content, the better.

The higher the calcium content, the better the calcium supplement effect is also a major misunderstanding for many fruit growers. Although the effect of calcium supplement is directly related to the content of calcium in foliar fertilizer. But it is not the higher the calcium content, the better, because some raw material calcium chloride and calcium nitrate have the characteristics of high calcium content. Generally, it can reach about 35%, but the calcium supplement effect of these two kinds of calcium is not very good. Because the existing form and activity of the modification are relatively low, the calcium absorption rate of trees and fruits is low.

The above is a brief introduction to the misunderstandings of apple calcium supplement. That's all for today's introduction. This article is for reference only. I hope it can help you all.
