Fruit trees are excessively fertilized

Some fruit farmers believe that the fruit trees are more fertile and fertilized. As long as they are willing to invest, the fruit trees will be productive, but it is not. Excessive fertilization of fruit trees will not only increase the yield, but will lead to many adverse consequences.

Affect 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 be reduced, the hardness will be lowered, the coloring will be poor, and storage will be imperfect, thereby reducing the commercial value.

Affect the quality of shoots and buds

If excessive nitrogen fertilizer is applied in the autumn, the autumn shoots will grow, the leaves will be delayed, the branches will not be mature enough, and the winter will easily cause the strips. In addition, because the new shoots stop growing late, the nutrients in the shoots are insufficient, which is not conducive to the formation of full and strong flower buds, affecting the quality and yield of the next year.

Easy to cause poisoning

Due to the application of a large amount of fertilizer, the concentration of the soil solution is increased, so that the roots absorb the water and the inorganic salts, which causes the aboveground parts to wilting. If not remedied in time, the tree will die due to the inability to absorb water.

Causing imbalance of nutrients in the tree

There is an antagonistic effect between the nutrient segregants, that is, the presence of a certain nutrient segregant can inhibit the activity of another or a plurality of nutrient segregants, thereby affecting the absorption of the tree body. 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.
