Under the conditions of grass, spread the fertilizer on the grass. After fertilization in the whole garden, it is highly efficient. This method has a large fertilization area and is beneficial to root absorption, and is suitable for adult trees and densely planted trees.
Second, the ring (round) fertilization The annular groove should be opened under the projection of the outer edge of the canopy. When the amount of fertilizer is large, the ditch can be dug and deep. Cover the soil in time after fertilization. Suitable for saplings and initial fruit trees, trees that are too densely planted should not be used.
Third, the radiation ditch (radial) fertilization Ditched from the under the canopy, the inner end from the outer edge of the canopy projected slightly inside, the outer end extends beyond the outer edge of the canopy projection. Ditch 4-6, the width and depth are determined by the amount of fertilizer. Cover the soil after fertilization. This method of fertilization has fewer roots and can promote root absorption. It is suitable for adult trees, and trees that are too densely planted should not be used. When fertilizing in the second year, the position of the ditch should be staggered.
Fourth, fertilization in the ditch The fruit trees line up to the ditch, can open a number of strips, with the ditch with fertilization, timely cover the soil. This method is convenient for mechanical or animal work. Many orchards abroad use this method to fertilize, and the efficiency is high, but the orchard is required to be flat on the ground, and the ditch operation and irrigation are convenient.
