通过对不同耕法所形成的耕层剖面研究,分析了不同耕法形成的耕层结构特点。根据对不同耕层构造模式的生态功能试验分析,提出了苗带紧行间松、松紧兼备型耕层模式的构建,该构造对土壤水、气调节具有良好效果,能充分满足春玉米生长对耕层土壤的生态需求。采用此种耕层构造,对于促进玉米的生长发育、产量的提高具有明显效果。

Through the survey on soil layer profile of different tillage systems, we analyzed the plough layer construction trait of different tillage systems. According to the analysis on the ecological function experiment of different plough layer construction modes, we put forward the plough layer construction mode that had close seedling row and loose ridge furrow, which had a good regulation effect to soil water, soil air and could meet the ecological requirement of spring maize growth to the soil layer. And It was a obvious effect to promoting maize growth and increasing yield using this soil layer construction.
