The emergence of large branches of trees or young leaves and buds of whole trees atrophy, dryness, atrophy and loss of flowers and young fruits, and even death of entire trees. phenomenon. To avoid fertilizer damage, the following methods can be used: First of all, we must correctly choose the fertilization method.

The second is the correct choice of fertilizer. According to the stability of fertilizers and the effect of fertilizers on fruit trees, the probability of occurrence of fertilizer accidents is generally ammonium bicarbonate, ammonium chloride, ammonium sulfate, unripe farmyard manure, sulfur-based compound fertilizers, and sulfur-based fertilizers. Compound fertilizer and so on. If there is fertilizer damage after fertilization, it should be promptly remedied, and look for the corresponding large roots in the extension direction of the branches showing the symptoms of fertilizer damage. If it is found that the root part turns black and rot, it can be scraped with a cutter; if the root rot is severe, the affected part can be cut off and rotted. To the trunk can cut off the root from the main stem, and sun root for 1 to 2 days, with particular attention to avoid flooding.
