Fruit trees are harmful to excessive fertilization

One harm: excessive fertilization will cause an imbalance between the nutrients of the tree nutrients. The existence of a certain nutrient segregant can inhibit the activity of another or more nutrient segregants, thus affecting the tree to it. Absorption. For example, the application of nitrogen fertilizer in acidic soil should not be too much, otherwise it will be difficult for crops to absorb calcium ions. Excessive application of calcium fertilizer can induce crops suffering from zinc, boron, iron, magnesium and manganese deficiency. Excessive potassium use will also affect the absorption of calcium and magnesium ions by fruit trees.

Two pests: excessive fertilization is easy to cause fruit tree poisoning due to the application of a large amount of fertilizer, increasing the concentration of soil solution, making the roots of the fruit tree absorb water and inorganic salts difficult, causing the aboveground parts to wilting, if not timely remediation, the tree body can not be absorbed Death by moisture.

Three pests: affecting the quality of the fruit In the late stage of fruit growth, if a large amount of nitrogen fertilizer is applied, the sugar content of the fruit will decrease, the hardness will decrease, the coloring will be poor, and it will not be stored, thus reducing its commercial value.
