摘要: 为探究不同耕作方式对土壤理化性状及小麦产量的影响,2016-2017年在恩施市红庙试验基地结合传统免耕、深耕优点,采用耕层优化双行匀播技术进行试验,比较不同耕作方式下小麦产量及土壤理化性状差异。结果表明,耕层优化双行匀播技术可改善土壤理化性状。与深耕、旋耕相比,耕层优化双行匀播技术施作可使小麦产量增产10.64%和15.76%,同时可使小麦地上部生物量分别提高7.82%和9.16%。

Abstract: : In order to explore the effects of different tillage methods on soil physical and chemical properties and wheat yield, the study was conducted in 2016-2017 at the Hongmiao Experimental Base in Enshi city, combining the advantages of traditional no-tillage and deep tillage. The differences of wheat yield and soil physical and chemical properties under different tillage methods were compared. The results showed that the plough layer optimization and double-line even seeding technology could improve soil physical and chemical properties. Compared with deep tillage and rotary tillage, plough layer optimization and double-line even seeding technology could increase wheat yield by 10.64% and 15.76%, and increase aboveground biomass by 7.82% and 9.16%, respectively.

Key words: wheat, tillage, plough layer optimization and double-line even seeding, soil physicochemical properties, yield
