| 摘 要： | 针对农田耕层现状及存在的问题,从耕层变薄犁底层增厚,有机质减少地力下降地表裸露水（风）蚀严重等3个方面,分析农田土壤退化及不合理耕层形成的原因,通过总结前人研究结果,明确耕层构造的概念及类型,结合笔者多年研究提出“苗带紧行间松”合理耕层的概念及建立合理耕层构造的重要意义,以期为东北黑土保育、持续高效耕作及确保国家粮食安全提供一定理论参考依据. |

| Abstract: | As for the present and problem of cropland which tillage layer has become more and more thin with increased piow pan layer, soil organic matter has reduced with decreased produce capacity of cropland and water and wind erosion of cropland has become more and more severe, we analyzed the reason that soil deteriorated and poor tillage layer formed. Thought stud- ying the conclusions of other researchers, we indicated the concept and types of optimum tillage layer, meanwhile, we also pointed out the concept and important meaning of spacing tillage in order to protecting northeastern black soil, lasting tillage, guaranteeing the safety of grain. |
