Increasing fruit firmness Fruit firmness is positively correlated with calcium content in fruit. Experiments have shown that sufficient calcium content can increase fruit firmness, because calcium can inhibit the activity of polygalacturonase (PGA) in fruits and reduce cell wall Decomposition, delayed fruit softening. In addition, calcium ion is a protective agent for cell membranes. The maintenance of calcium function on the membrane is considered to be an extracellular effect, which is the result of Ca2+ binding to the outer surface of the plasma membrane. Calcium can prevent the extravasation of cells and vacuoles and increase the protective enzyme activity. And the content of protective substances is beneficial to the protection of cell membrane structure and prevent the fruit from becoming senile.
Prolonged storage time Calcium is closely related to the stability of tissue structure and enzyme activity in fruits. The calcium content in fruits is high, which can slow down the physiological activities of fruits after picking, delay their aging and prolong their storage time.
Promoting the absorption of nitrogen, phosphorus, and potassium can promote the absorption of potassium, phosphoric acid, and nitrate nitrogen.
Therefore, in the later stages of fruit growth, proper calcium supplements have many benefits for fruit trees, which can not only prevent fruit cracking, but also extend the fruit harvest period. It can increase the application of high-calcium and potassium-based water-soluble fertilizers in time, which can increase production and increase income.
