Fruit tree spring dressing to avoid fat damage

The first step is to choose the right fertilization method. Fruit tree fertilization is best applied in combination with decomposed soil and fertilizer. When using annular groove and radiation ditch, pay attention to the too deep or too large a distance; the fertilization of the ditch should not be fertilized in the direction of extension of the big root (can be compared with the direction of the big branch), preferably fertilization between large branches; non-repetitive fertilization ( The fertilization area should be changed every year); the fertilization site should not be too close to the trunk. Secondly, the correct choice of fertilizer, according to the stability of fertilizer and the effect of fertilizer on fruit trees, the probability of occurrence of fertilizer accidents is generally ammonium bicarbonate, ammonium chloride, ammonium sulfate, unfertilized farmyard manure, sulfur-based compound fertilizer, sulfur base Compound fertilizer, etc.
