What about the fertilizer damage of fruit trees?

In the process of fruit tree planting, if you accidentally apply too much fertilizer, resulting in fertilizer damage, affecting the growth of fruit trees how to do. This is a problem that many people will encounter when planting all kinds of fruit trees. if this happens, of course, it is to look for better ways to protect the roots of fruit trees. Because fat damage is mainly root injury, then what specific methods to remedy it? let's take a look at it now.

1. Symptoms of obesity injury

After the occurrence of fertilizer damage, serious growth decadence, growth is very slow, no growth, leaves dry, stem dry. Sometimes the branches will die and the serious tree trunks will die. The root system is the first to suffer, suffer directly, dry up, burn the root, no longer grow, the root turns reddish brown and blackens gradually. The fruit of a tree that is bearing fruit will eventually fall.

2. The cause

Fertilization is too close to the trunk, cut off the big root, bring damage, fertilizer dig too deep, directly contact the main root, hurt the root. Fertilizing too much, the concentration of soil solution is too high, the root system can not absorb. Fertilization is uneven and too concentrated. The use of unfermented fermented fertilizer will ferment in the soil, generate heat and burn roots. Fertilizing without watering will also hurt the roots, so be extra careful when using burning fertilizers such as urea. Do not mix many kinds of fertilizers, pay attention to the concentration of foliar fertilizer.

3. Preventive measures

Uniform fertilization, fertilization and soil should be mixed evenly, more mixed soil. Farm manure must be fully ripened and applied. Decentralized fertilization, do not be too concentrated. Reasonable topdressing, do not fertilize too many times. Fertilize farther from the trunk and fertilize at the dripping line of the canopy. Strictly control the concentration of foliar fertilizer. Fertilizing and digging the soil without pressure will hurt the roots.

4. Remedial measures

After the symptoms of fertilizer injury, timely use flood irrigation, dilute the concentration of soil solution, dig up the soil of the root system, check the root system for damage, repair the root system, and replace the new soil after drying the root for a few days, preferably the unfertilized topsoil. Cut off dead leaves, spray more water, and if the root system is seriously damaged, the root system should be cut off.

If fertilizer damage occurs to fruit trees, the roots will be damaged first, but the first thing that can be seen is on the leaves. Timely remediation is mainly improved by diluting fertilizer and changing soil.
