Management after planting (1) 1. Fertilization and Irrigation: Fertilization and irrigation are management measures that provide the necessary nutrients in a timely and appropriate manner according to the needs of tree growth and flowering. The main methods of fertilization are rhizosphere fertilization and extra-root fertilizer. Rhizosphere fertilization is the application of fertilizers to deeper and farther places where the roots are concentrated, in order to induce the roots to extend deep and wide. Immediately after fertilization, water should be applied to promote the absorption and utilization of nutrients. The top-dressing fertilizer can be combined with pest control. The chemical fertilizer is diluted and mixed with pesticides, sprayed on the stems and leaves of plants, and directly absorbed and utilized by plant leaves. The methods for rhizosphere fertilization include: (1) Trench fertilization: about one-fifth of the projection along the canopy, and digging of circular or arcuate trenches 20-40 cm in depth and 20 cm in width, moving outwards year after year; ( 2) Radial fertilization: Dig 4-6 trenches at a certain distance from the trunk within a width of 20-40 cm and a width of 20-40 cm in depth. (The length is based on the circumference of the canopy. The position should be changed when the next year is applied.); (3) Point fertilization: In the canopy projection range, evenly dig more than a dozen pits... Spread the fertilizer evenly into the ditch and cover the soil. If the fertilization is done several times a year, the positions of the cavities should be staggered. Fertilizer quantity determination: how much fertilization should be determined based on the following aspects: (1), soil fertility: less soil fertility, fertility and more small facilities; (2), tree potential: tree potential is less or not applied. (3)Flower and fruit load:Flowers and fruits are loaded with multiple loads, and the amount of load is small; (4) Fertilizer type and quality: Refer to the instructions for use of the field home. The principle of fertilization time: spring and summer with nitrogen fertilizer, phosphorus fertilizer (urea, diamine, etc., promote long foliage, root system), should be added to the autumn potash fertilizer, promote lignification of shoots and fruit quality, after entering September should be controlled Water and fertilizer to prevent late greed green.
