Fruit tree near fertilization

For many years, the method of applying fertilization on the outer edge of the canopy has been used in fertilizing the fruit trees. Especially in the plain areas where the cultivation density is high, the soil is deep and fertile, root extensities have appeared to varying degrees, and the crowns are large and branches are grafted. The external canopy closure, internal guilt emptiness, flower buds are not substantial, the resulting parts are shifted outward, the yield is low, and the quality is poor, which has a certain relationship with the location of fertilization.
The "Approaching near fertilization" method of fruit trees is an adult tree that enters the result period. Each year, 50 cm away from the tree trunk, a shallow, deep, narrow and wide radiation groove is drilled, and fertilization is cycled to achieve both internal and external root support and excessive epitaxy is controlled. Appropriate concentration, this will not only save fertilizer, reduce costs, more effective control of the expansion of the tree crown, so that the internal branches of the crown robust, to the "close supply" principle. In the past few years, under the same pruning and other management conditions, using the same amount of fertilization and using the “near fertilization” method had a significant effect on the control of branching, canopy closure, and outward displacement of the resulting parts, resulting in good results. Effect.
