Fruit tree damage
Some peasant friends discovered that 1-2 weeks after fertilization, the large branches of fruit trees or the leaves and buds of the whole tree were shriveled and dried, and the flowers and young fruits were atrophied and fell off. The strip bark on the back showed watery ulceration. In severe cases, all the large branches died. The entire tree died. The main reason for this phenomenon is the burning of fertilizer.
The roots of spring fruit trees dormancy end, the vitality of root cells is increased, the growth rate is accelerated, and the root epidermis is young, which is more sensitive to fertilizer. Fertilizers tend to form high-salt environments in the root regions of fruit trees, causing damage to root-transport tissues and roots, thereby blocking nutrient supply, and the corresponding branches begin to shrink and die.
As the saying goes, "a pair of one", and the direction of the extension of the root is generally consistent with the direction of the corresponding branch of the fruit tree. The above problems occur on large branches, and the corresponding big roots will turn brown, black, and even rot.
Peach in the north is the most prone to damage, followed by apple, orange, grapefruit, pear, grape, chestnut, jujube and other fruit trees.

Fertilization of fruit trees is best combined with the use of composted soil and fertilizer. When using ring groove and radiation groove fertilization, pay attention to not apply too deep or too close to large roots; do not apply fertilization in the extension direction of large roots (in the direction of large branches), and it is best to fertilize between big branches; do not repeat fertilization ( The fertilization area should change every year; the fertilization area must not be too close to the trunk. 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, unfamiliar farmyard fertilizers, chlorine-based compound fertilizers, chlorine-based compound fertilizers, and sulfur-based compound fertilizers. Mixed fertilizer, sulfur-based compound fertilizer.
If the fertilization consequences tree appears to be harmed, timely remedy is the key to avoiding greater losses, and it cannot be held in luck to delay treatment. The fertilizer damage should be discovered in time, and the corresponding large roots should be found in the direction of the branches showing the symptoms of fertilizer damage. If the root part is found to be black and rotten, it can be scraped off with a cutter; if the root rot is severe, the victim part can be cut off and the rotting can be taken from the main part. The cadres cut off the roots and dried them for 1-2 days. Special attention should be paid to avoid flooding.
The above is the introduction of some methods for fertilizing and avoiding fertilizer damage in spring fruit trees. Fruit farmers can refer to the above methods and rationally apply fertilizer according to actual planting conditions.
