Everyone knows the importance of NPK. It is not enough to know about trace elements. In the past, when organic stalk fertilizer was used in large quantities, some trace elements could be added. Nowadays, the use of straw fertilizer is less and less, and the output of fruit is increasing. The rapid reduction of trace elements leads to many physiological diseases in fruit trees, such as yellow leaves, lobular leaves, capsules, chicken feet, etc.; weakened trees can also cause invasive diseases such as root rot, rot, blight, Ring disease and so on. Therefore, experts reminded that more than 90% of physiological diseases are caused by deficiency, such as iron deficiency yellow leaves, zinc deficiency leaflets, calcium deficiency and zinc pears, chicken paw disease, and boron deficiency fruit seed dysplasia. This shows that trace elements are as important as a large number of elements, and each bears responsibility. Fruit trees are the same as human bodies. If any one element is missing, it will lead to unhealthy constitution, which will affect the yield and quality of fruit trees. Therefore, it is very necessary to supplement trace elements.

If there is no soil applied, it can be sprayed by two thousandths after the falling flower. The disadvantage is that the effective period is short. The advantage is that it works quickly and can be used multiple times.
