摘　　要：浅松作业是保护性耕作中推广使用的一种表土作业方式,适用于旱作保护性耕作的播前作业,能够达到松土、除草、整地等目的,也可以用于中耕除草作业。试验结果表明,该作业有良好的除草作用,能显著地提高地表平整度,降低表土容积密度,对根茬覆盖和土壤水分影响不显著,基本上满足了保护性耕作对土壤的要求。Topsoil cultivation is a new way of surface treatment in conservation tillage. It is mainly used in loosening soil, weeding, flattening the land before sowing in conservation tillage. It is also used as cultivator in trash cultivating. The test results show that shallow-tillage kills grasses remarkably, improves soil surface obviously, decreases the surface soil bulk density while it has no effects on residue covering and soil moisture content, which satisfies the needs of soil in conservation tillage.
