使用农业机械,实行深达24厘米以上的中耕深松,能打破犁底层、增加活土层、有利于作物根系发育,能够增强保土、保肥、抗旱、抗涝、抗倒伏的能力,促进作物早熟,一般增产幅度在10%左右.但是,由于深松时没有掌握好时机或深松方法不当,则达不到预期效果,甚至会适得其反.深松中应注意以下几个问题:1.严格掌握中耕深度,耕深一般应达到24厘米,否则打不破犁底层,就会造成假深松.实行大垄深松,必须有相应的深松机具,对现有的7铧 The use of agricultural machinery, the implementation of more than 24 cm deep cultivating deep pine, can break the plow bottom, increase living soil layer, is conducive to crop root development, can enhance soil conservation, fertilizer, drought, waterlogging, lodging resistance and promote Crop early maturity, the general rate of increase of about 10% .But, because the deep pine is not a good time to grasp or improper method, you can not achieve the desired effect, or even counterproductive .Subseason should pay attention to the following questions: 1. Strict Grasp the depth of cultivation, farming depth should generally reach 24 cm, or pound the bottom layer will not break, it will cause false deep subsoiling. The implementation of deep furrows deep loose, there must be a corresponding subsoiler equipment, the existing 7 Hua
