1. The whole garden general application method: first apply the fertilizer to the orchard ground, and then combine the orchard to plow or deep winter ploughing, and turn the fertilizer into the soil layer. This method is mainly used for large-scale fertilization of mature fruit trees or densely planted orchards in mature orchards or densely planted orchards. Most of the fertilizer is mainly crude fertilizer. 2. Range of tree trays: Fertilizers are applied in a concentrated manner within the tree tray. After fertilization, deep cultivating is also carried out, and the fertilizer is turned into the soil layer. This method is suitable for young orchards. The advantage is that it is more concentrated than the whole garden, and generally uses a combination of crude fertilizer and refined fertilizer, slow-acting and quick-acting. 3. Annular groove fertilization method: According to the breadth of the root extension of the fruit tree, a trench of 40 to 60 cm deep and 40 cm wide is dug in the outer edge of the canopy. The fertilizer is then applied to the ditch and covered with soil. This method is suitable for applying organic fertilizer to the orchard, the new orchard and the young orchard with small canopy in winter or early spring. 4. Radial groove fertilization method: Take the trunk as the center, and evenly dig 5 to 6 shallow grooves radially outside the canopy. The inside is shallow and deep, and the canopy is 20 to 30 cm deep at the projection of the ground. Then the fertilizer is applied and covered with soil. This method is suitable for the age-old orchard topdressing. 5. Acupoint application or infusion fertilization method: acupuncture is to dig a few 30-60 cm deep hole around the crown to apply the fertilizer into the hole; injecting fertilization method is to use a soil drill to drill a hole in the tree tray around the trunk, 50 cm deep Left and right, inject the well-mixed fertilizer into the hole. The above two methods are suitable for orchards or densely planted orchards in arid areas, mostly based on liquid fertilizer. 6. Ditch fertilization method: In the orchard, along the direction of the fruit trees, each line is opened with a long ditch 50 cm wide and 40 cm deep, and the fertilizer is applied into the ditch. This method is suitable for large-scale orchard selection and can be mechanized. Disclaimer: Some articles on this website are transferred from the Internet.
