Autumn fruit tree fertilization method

1. Ditch application: open the fertilization ditch at the position of the canopy drip line, the shape can be opened into a ring, curved, rectangular, etc., the ditch depth is 40 cm to 50 cm, and the groove width should be determined according to the amount of fertilizer applied, such as the amount of fertilizer applied. The ditch is wide. The bottom of the ditch should be flat, and after the water and fertilizer are drenched, the dry fertilizer will be sprinkled in the ditch, and the soil will be covered immediately after the water is dried. Before the fertilization, the roots in the exposed trench should be flattened along the trench wall, and the cut should be smooth to prevent mold and rot, so as to facilitate the early healing of the wound and the occurrence of new roots. In the case of acid soil, lime is applied to each layer of grass fertilizer to reduce soil acidity and accelerate decomposition of the fertilizer. When the fertilizer is lowered, the coarse fertilizer such as branches, leaves, grass, etc. should be placed on the bottom layer, and the upper layer should be placed with organic fertilizer. Apply a layer of soil to each layer of fertilizer. The last covering soil should be 30 cm to 35 cm above the ground to prevent the fertilizer from decomposing and then sinking water, causing rotten roots. The time from trenching to covering soil should be determined by the circumstances. In case of high temperature weather, it should be sooner rather than later, usually after 2 days to 3 days.
2, implementation: In the adult orchard, the crown has been closed, the root group is intertwined in the soil layer of the entire orchard. The specific operation is to apply fertilizer every time, on the side of the plant, along the plant spacing or row spacing, the topsoil is opened, the soil should be shallow near the trunk (8 cm to 10 cm), and the distance from the trunk should be deep (40 cm to 50). cm). In case of autumn drought, you should first spray water and fertilizer, then spread the fertilizer evenly, and then cover the soil after drying.
