Trace elements are indispensable for humans, animals or plants. Calcium deficiency in humans and animals will affect the normal development of the body. Calcium deficiency in plants will also cause growth lesions. Feed grade calcium formate is a calcium-soluble foliar fertilizer with high activity, which can be sprayed directly on the foliar surface, with high absorption and utilization rate, low production cost and easy operation.

At present, in vegetable production, people only pay attention to the input of a large number of elements nitrogen, phosphorus and potassium fertilizers due to the influence of traditional fertilization habits, and often ignore the supplementation of medium elements calcium and magnesium fertilizers, resulting in physiological calcium deficiency and magnesium deficiency in vegetables. The symptoms worsened year by year, causing great losses to vegetable production. The effect of calcium on crops is far underestimated by us.

Nutritional function of calcium

1. Calcium can stabilize biofilm structure and maintain cell integrity

Calcium is an essential nutrient for plants and an important component of cell walls. Calcium-deficient cells in plants cannot divide normally, and in severe cases, the growth point is necrotic, and physiological diseases are prone to occur. A stable biofilm environment can improve the resistance of crops to retrograde. At the same time, because calcium can increase the selectivity of the cell membrane for the absorption of potassium, sodium and magnesium ions, and potassium and sodium ions can promote the stability of cells, thereby improving the retrograde resistance of crops. To put it bluntly, calcium can improve the retrograde resistance of crops.

2. Can prevent premature aging

The senescence of plants is closely related to the production of ethylene in the body, and calcium ions can reduce the biosynthesis of ethylene through the regulation of cell membrane permeability, thereby preventing premature senescence of crops. If you don’t want the crops to die early, the application of calcium fertilizer is indispensable.

3. Stabilize the cell wall

Calcium deficiency causes the cell wall of apples to disintegrate, softening the cell wall and the mesocolloid layer, and then the cells rupture, causing water heart disease and heart rot.

4. Calcium also has a swelling effect

Calcium can promote cell elongation, which also plays a role in swelling. At the same time, it can also promote the elongation of root cells, thereby promoting root growth.

5. Extend the storage period

When the calcium content in the ripe fruit is high, it can effectively prevent the rotting phenomenon in the post-harvest storage process, prolong the storage period and increase the storage quality of the fruit.

In fact, if you understand the various nutrient elements of crops thoroughly, you will find that many diseases are mainly caused by the poor resistance of crops caused by unbalanced nutrition. Balanced nutrition, fewer diseases and fewer insects.

After talking about the nutritional function of calcium, what kind of loss will calcium deficiency cause?

In the absence of calcium, the growth of plants is stunted, and the internodes are shorter, so they are generally shorter than normal plants, and the tissue is soft.

The apical buds, lateral buds, root tips and other meristems of calcium-deficient plants first appear nutrient-deficient, perishable, and young leaves are curled and deformed. The leaf margins begin to turn yellow and gradually become necrotic. disease; tomato, pepper, watermelon, etc. have rotten heart disease; apples have bitter pox and water heart disease.

Therefore, calcium supplementation is really important, and it does not necessarily have to be supplemented after the fruit has grown, but supplemented in advance, usually before flowers.

Well, since calcium has such a great effect, how should it be supplemented?

Many soils in the north are calcareous soils that are rich in calcium, but in the end, everyone found that they would still be deficient in calcium, and the new leaves were still deficient in calcium. What’s going on?

That is a physiological calcium deficiency, that is, there is so much calcium, but it is useless.

The transport capacity of calcium in the xylem often depends on the intensity of transpiration, therefore, the calcium content in the old leaves is often particularly high; however, the transpiration of the terminal buds, lateral buds, and root tips of the plant is relatively weak, and it is supplemented by transpiration. Calcium will be much less. To put it bluntly, he is not as strong as Lao Ye, and he can’t rob others.

So, no matter how calcium-rich the soil is, foliar spray supplementation is still essential. This is why the calcium supplementation of leaves works well. Because the calcium absorbed from the soil cannot reach the new leaves, the old leaves are kept for themselves.

A good calcium fertilizer is inseparable from calcium formate,

Calcium formate is widely used in calcium fertilizers. It is rich in small molecular organic calcium, has high utilization rate, fast absorption, and is not easy to be fixed by soil; it can meet the absorption of calcium in crop growth period. Effectively prevent physiological diseases of crops caused by calcium deficiency.
