2, deepening the application as appropriate shallow application. The traditional method of applying the base fertilizer requires excavation of a trench of 60 to 80 cm depth, and filling the straw and organic fertilizer to the bottom layer during backfilling. In fact, the absorption roots of fruit trees are mostly concentrated in the ground 20 to 50 cm. If the fertilization is too deep, the fertilizer efficiency is low. Therefore, the application of base fertilizer should not exceed 50 cm deep underground.
3, change the local fertilization for the whole garden fertilization. Local fertilization is more common in production, such as the ditch method and the radial ditch method. This method is more suitable in the sapling stage, but in the fruit-bearing period, the fertilization is carried out by using the gully, the fertilizer is concentrated in the local area, and is not easily absorbed by the root area; under drought conditions, the concentration of the soil solution around the fertilizer is high, which easily leads to sap Backflow, burn the fine roots. Therefore, in the fruit-bearing period, the whole garden should be applied to spread the fertilizer evenly to improve its utilization.
