浅穴耕作在美国应用较早 ,其在减少径流、减少侵蚀方面有很大的作用。由于地表浅穴的存在能够贮存雨水 ,减少地表径流的发生 ,并且能够增加土壤的含水量。据试验研究 ,浅穴耕作比翻地、耙地的土壤流失量低 10倍 ,比垄作耕法低 2 5倍。浅穴耕作不但适合旱作地 ,而且适合灌溉地 ,它可以应用于多种土壤、多种作物。实施浅穴耕作棉花增产 32 %以上 ,高梁增产 170 0kg/hm2 。但实施浅穴耕作也有减产的现象 ,这主要是由于浅穴耕作区除草不佳 ,或积水过多 ,土壤通气减弱或不利于播种及其它耕作的原因所致。
Shallow tillage was applied earlier in the United States, which has a significant role in reducing runoff and reducing erosion. Due to the existence of shallow surface, it can store rainwater, reduce the occurrence of surface runoff, and increase the water content of soil. According to the experimental study, the shallow hole tillage is 10 times lower than the land loss and harrowing, 25 times lower than the ridge tillage. Shallow tillage not only suitable for dry land, but also for irrigated land, it can be applied to a variety of soil, a variety of crops. Implementation of shallow hole cultivation of cotton yield more than 32%, sorghum yield 170 0kg / hm2. However, the production of shallow hole tillage has also been reduced. This is mainly due to poor weeding in the shallow hole tillage area, excessive water accumulation, weakened soil aeration or adverse effects on seeding and other tillage.
