一、环状沟施。在树根外围挖一环形沟。其宽30至50厘米,深15至45厘米。然后将表土与基肥混合施入,多适于幼树。 二、放射状沟施。在距树干1米的地方,挖6至8条放射状沟、沟宽30至60厘米,深15至40厘米,长度抵树冠外缘。为避免损伤大根,挖沟时靠近树干内侧要浅,向外逐渐加深并逐年更换位置,扩大施肥面,促进根系均衡发展。此法伤根较少。是较理想的方法之一。 三、沟状施肥。在果树行间或株间,距树干1米
First, the ring ditch facilities. Dig a ring-shaped ditch outside the root of the tree. It is 30 to 50 cm wide and 15 to 45 cm deep. Then topsoil and base fertilizer mixed into the more suitable for saplings. Second, radial ditch facilities. At a distance of 1 meter from the trunk, dig 6 to 8 radial furrows with a furrow width of 30 to 60 cm and a depth of 15 to 40 cm. In order to avoid damaging the large roots, when digging the ditch, the inside of the tree trunk should be shallower, the depth should be gradually deepened and the location should be changed year by year, the fertilizer surface should be expanded to promote balanced root development. This method less injured roots. Is one of the more ideal way. Third, ditch fertilization. Between the rows of fruit trees or between the trees, 1 meter away from the trunk
