为探讨休耕(不耕作)和治理式休耕(翻耕、撒石灰、种植绿肥等措施)对土壤肥力水平的影响,采用野外采样、室内测定的方法,对比分析了宁乡市传统耕作、休耕及治理式休耕条件下农田土壤的理化性质.结果表明:治理式休耕降低了土壤容重,增加了土壤总孔隙度,提高了土壤有机质含量,提升了土壤肥力,使土壤养分得到合理利用,土壤资源得到了有效的保护,是宁乡地区合理的耕作模式.

In order to study the effects of fallow（no tillage） and managed fallow（tillage, lime sprinkling, green manure planting, etc.） on soil fertility, the physical and chemical properties of farmland soil under traditional tillage, fallow and managed fallow were compared and analyzed by field sampling and laboratory measurement. The results showed that the management fallow reduced soil bulk density, increased soil total porosity, increased soil organic matter content, increased soil fertility, made rational use of soil nutrients, and effectively protected soil ...
