Orchard soil fertilization
Organic fertilizers and most inorganic fertilizers (fertilizers) should be applied below the surface of the soil, which is beneficial to the absorption of the roots, and the robust trees, which can also reduce the loss of fertilizer.
First, fertilize the entire garden fertilizing the whole garden, spread the fertilizer and soil with hoe or turn it into the soil. Under the conditions of grass, sprinkle the fertilizer on the grass. After the fertilization in the whole garden, it is suitable for irrigation and has high efficiency. This method has a large area of ​​fertilization, which facilitates root absorption and is suitable for adult trees and densely planted trees.
Second, ring (ring) fertilization ring groove should be opened under the projection of the outer edge of the crown, when the fertilization amount is large, the ditches can be excavated and deepened. Apply soil immediately after fertilization. Suitable for saplings and early fruit trees, too densely planted trees should not be used.
Third, the radiation groove (radial) fertilization from the canopy under the outer groove, the inside of the end of the tree from the outer edge of the projection of a little inside, the outer end of the canopy extends beyond the outer edge of the projection. Ditch 4-6, width and depth depending on the amount of fertilizer. Cover soil after fertilization. This method of fertilization has less root damage and can promote root absorption. It is suitable for adult trees. Trees that are too densely planted are not suitable for use. In the second year of fertilization, the position of the ditch should be staggered.
Fourth, the ditch and fertilization between the rows of fruit trees to open the ditch, you can open more than one, with the ditch with fertilization, timely cover soil. This method is convenient for mechanical or animal work. Many foreign orchards use this method to fertilize and have high efficiency. However, it is required that the orchard be flat on the ground, and it is necessary to facilitate the operation and irrigation of the ditch.
