在４年多的玉米传统耕作、深松覆盖和免耕覆盖耕作研究的基础上，分析研究了３种耕作措施下的土壤物理性状、作物产量，以及社会、经济与生态效益。结果表明，深松覆盖和免耕覆盖具有改善土壤结构、增加土壤含水量、提高作物产量、减少作业量、降低成本、增加收入、减少地表径流等功能。从土壤物理状况、作物生长以及产量来看，免耕可以持续４年以上而不用翻耕，而土壤仍能保持良好的状态，并获得较高的产量；深松虽然比免耕的土壤含水量略高，但并不显著，而产量和盈利却比免耕少，因此深松并非必需进行，至少不必年年进行。
Based on more than four years of research on traditional tillage, subsoiling and no-tillage maize cultivation, the soil physical characteristics, crop yield, and social, economic and ecological benefits under three tillage measures were analyzed. The results showed that subsoiling and no-till coverage could improve soil structure, increase soil water content, increase crop yield, reduce workload, reduce cost, increase income and reduce surface runoff. From the aspects of soil physical condition, crop growth and yield, no-till can last more than 4 years without tillage, while the soil can still maintain a good condition and obtain higher yield. Although no-tillage soil subsidence Slightly higher, but not significant, while yields and earnings are less than zero tillage, so subsoiling is not necessary, at least not every year.
