摘要
采用空间位移法,将砂土、砂质黏壤土、砂质壤土3种不同质地土壤移到同一地点的水泥池小区上,研究土壤质地对玉米产量的影响。结果表明,无论是免耕还是翻耕,玉米产量均表现为砂质黏壤土>砂质壤土>砂土。不同质地的土壤玉米产量均表现为翻耕比免耕高,但差异不显著。根据玉米产量构成因素分析,不同土壤质地条件下玉米产量的差异主要由单穗粒重和千粒重的变化引起。
Maize was planted in the cement pit,in which different textural soils including sandy,sandy clay loam and sandy loam were filled as the natural status.The effects of soil texture on the yield of maize were studied.The results showed that whether no-tillage or conventional tillage maize shown as sandy clay loam sandy loamsandy.Regardless of which kind of texture soil,maize yield of conventional tillage is higher than no-tillage,but the difference was not significant.According to the analysis of maize yield component found that the difference of maize yield is mainly due to the single spike kernel weight and 1000-grain weight.
