在有机肥不足特别是瘠薄干旱的山地果园,基肥最好集中穴施,以充分发挥肥效。方法如下: 1.挖贮养穴。在果树根系的集中分布区(一般在树冠投影的边缘向内50—70厘米处),挖直径20—30厘米、深40—50厘米的贮养穴。穴的数量根据树冠的大小和土壤条件决定,一般幼树设3—5个,成树设5—6个。 2.绑草把。草把的粗度比穴的直径稍细,长度比穴深短3—5厘米,捆结实。材料用玉米、麦秸、杂草等。捆好把后在0.2％的尿素液中浸泡一段时间,使其充分吸水。 3.穴的设置。把草把放入穴内后,填入混有少量过磷酸钙(每穴
In the absence of organic fertilizer, especially infertile mountain orchards, the best base fertilizer to concentrate, in order to give full play to fertilizer. The method is as follows: 1. Digging storage points. In the centralized distribution of the root system of fruit trees (usually 50-70 cm inward from the edge of the canopy projection), dig the storage hole 20-30 cm in diameter and 40-50 cm in depth. The number of holes according to the size of the crown and soil conditions, the general set 3-5 young trees, trees set up 5-6. 2. tied grass. Thickness of the grass than the diameter of the hole a little thin, the length of the hole than the short 3-5 cm, tied solid. Materials with corn, wheat straw, weeds and so on. Bind well after soaking in 0.2% urea solution for a period of time to make it fully absorb water. 3 points set. Put the grass into the hole, fill in mixed with a small amount of superphosphate (per hole
