摘要
以通过对土壤容重、土壤紧实度、土壤含水量、玉米产量、效益及水肥利用率的测定和分析,研究传统旋耕、少耕、免耕3种耕作方式对辽西地区土壤物理性状及玉米产量的影响。结果表明,少免耕可显著增加播前耕层土壤含水量,降低底层土壤紧实度,提高玉米产量及水肥利用效率。
By measuring and analyzing the soil bulk density,soil compactness,soil water content,maize yield,efficiency and water and fertilizer utilization rate,this paper studied the effects of three tillage methods of traditional rotation tillage,minimal tillage and no tillage on soil physical properties and maize yield in western Liaoning province.The results showed thmt:Minimal and no-tillage significantly increased soil water content before sowing,decreased soil compactness,and improved maize yield and water and fertilizer utilization efficiency.
