First, the whole garden general method first applies fertilizer to the orchard ground, and then combines orchard ploughing or winter deep cultivating, turning fertilizer into soil. This method is mainly used for large-scale fertilization of mature fruit trees or densely planted orchards in mature orchard orchards with full roots. Most of the fertilizer is mainly coarse fat.
Second, the tree-pan seedlings are applied in a concentrated manner in the area of ​​the tree disk. After fertilization, deep-middle ploughing is also carried out and the fertilizer is turned into the soil. This method is suitable for young orchards, and has the advantage of being more concentrated than the whole garden general method fertilizer, generally using a combination of coarse fat and fine fertilizer, slow-effect and quick-effect combined fertilizer.
Third, ring groove fertilization method According to the breadth of the extension of the roots of fruit trees, in the outer edge of the canopy dig a deep ditch of 40 to 60 cm, width 40 cm. The fertilizer is then applied to the ditch to cover it with soil. This method is suitable for applying organic fertilizer to barley orchards, orchards and younger orchards with small canopies in winter or early spring.
Fourth, the radial groove fertilization method to the trunk as the center, radially to the outside of the crown to dig 5 to 6 shallow ditch, shallow inside and outside depth, to the crown at the ground projection depth of 20 to 30 cm, then applied fertilizer and cover soil. This method is suitable for top-dressing orchards.
V. Acupuncture or injecting fertilizing method Acupuncture points are used to dig a few soil depths of 30 to 60 cm around the canopy, and apply the fertilizer into the holes. The injection fertilization method is to drill a hole around the tree trunk with a dirt drill. The depth is about 50 cm. , injecting a good fertilizer solution into the hole. The above two methods are suitable for arid orchard areas or densely planted orchards, with liquid fertilizers as the main components.
Six, row fertilization method in the orchard along the direction of fruit trees, each line open a width of 50 cm, about 40 cm deep ditch, the fertilizer applied to the ditch. This method is suitable for large-scale orchard selection and can be used for mechanized operations.
