How to fertilize the big apricot?

  Because of its cold tolerance and drought tolerance, most of the apricot trees are planted on the slopes of poor ridges, and because of their strong roots, they are scattered throughout the park. Therefore, it is difficult to plough and the land preparation standards are not high when planting trees, often resulting in soil compaction. Poor permeability, prone to soil-borne diseases (such as root rot), fertilization difficulties, moderate tillage and other phenomena, the need for fertility conditioning.

      Fertilization period   The young apricot trees are only chased once a year, and the time is before and after germination; the tree can be traced to the second fertilizer in the first fruit stage, once before germination, once before the hard core period; Fertilizer, once 7-10 days before flowering, once before the hard core period, and another before harvesting until the freezing. In addition, combined with the prevention and control of pest and leaf foliar fertilizer 2-3 times.

      Fertilization method: (1) Round groove fertilization: that is, in the outer edge of the canopy, dig deep 40-60cm (application base fertilizer) or 30-40cm (application of topdressing), 30-50cm wide annular groove, in the ditch Apply fertilizer. (2) Radiation-type fertilization: that is, the main trunk of the big apricot tree is about 1 meter away, and 4-6 holes are drilled to a depth of 30-50 cm. The groove length is longer than the outer edge of the canopy. Wide, the fertilizer is applied according to the amount in the ditch, and the position of the ditch should be rotated year by year. (3) Fertilization in the ditch: that is, a straight groove is opened between the rows of the big apricot trees or between the plants and the outer edge of the canopy, and the fertilizer is applied. Depending on the amount of fertilizer, it can be used to ditch and fertilize at one time, or to change the position of the groove between rows or plants year by year. The depth and width of the groove are the same as the annular groove. (4) Fertilization in the whole garden: In the fruit-bearing period, the trees in the flat apricot garden can spread the fertilizer evenly into the ground of the whole garden when the canopy is large, the branches are interlaced or the space is not suitable for trenching, and then the tillage is less than 20cm. In the soil layer, at this time, since the underground root system has been covered with the whole garden, the whole garden fertilization can meet the needs of tree growth.
