Hanging bottles on fruit trees means hanging bottles containing fertilizer solution or liquid medicine on the trunk. The fertilizer solution or liquid solution in the bottle is directly transported to the branches and leaves through the trunk in the trunk, so as to achieve the purpose of supplementing the fertilizer solution or preventing pests and diseases. Its advantage is that the input fertilizer or pesticide is not affected by the conditions of the rhizosphere soil and directly enters the tree body. Therefore, it is generally used in a small amount and has quick effects, and has the advantages of water saving, fertilizer saving (drug), labor saving and quick effect. In recent years, it has been widely used in gardening and fruit tree cultivation. However, it has been observed that some localities have a certain amount of blindness in using this technology, and they should be cautious when using it.
1. It is easy to cause mechanical injury. Frequent use of this method to fertilize pests in fruit trees will cause mechanical damage to the trees, scars on branches, and infection by some parasitic pathogens, sometimes leaving intractable wounds, affecting growth and ornamental quality. Suspended bottle fertilizer application should be used as an auxiliary method and should not be abused.

2. Some fertilizers or liquids should not be used this method. The use of hanging bottles of fertilizer should be based on specific circumstances. If the fruit tree suffers from some deficiency symptoms, only when the soil application or foliar spraying is not effective, the hanging bottle can be used to supplement the fertilizer. Not all fertilizers are suitable for this method. Only the nutrients in the fertilizer can be used in the catheter. Only suitable for transportation. Such as iron deficiency, calcium deficiency and other physiological diseases, the effect of soil application or foliar spray is not ideal, and the use of hanging bottles of fertilizer, the general performance of quick, long effect. In addition, when fruit trees are rotted due to roots, they are suitable for fertilization by hanging bottles.

3. Can easily cause local injury. Because of the limitations of drilling, the nutrients and liquids entering the tree are difficult to balance. If the local concentration is too high, it will cause damage to the tree, such as the leaves of the young leaves, the edge of the petal being scorched, the growth of the branches blocked, and even the branches and branches will die. Therefore, Normally grown fruit trees do not need to use hanging bottles.

In practical applications, it should also be noted that the water quality of the bottle is better, and the purity of the fertilizer is higher to prevent damage to the trees. Suspended bottles should be selected for appropriate time, and generally can be carried out after falling leaves in autumn or after leaves flow in spring and before budding. Trunk hole drilling should pay attention to the upper and lower branches of the catheter in the trunk, as far as possible to make the input liquid evenly dispersed. If the input liquid has a high acidity, the xylem will suffer different degrees of damage, affecting the normal absorption and transportation of nutrients by the trees.
