摘    要:通过2010,2011年的大田试验,对常规耕作、免耕、深翻、深松4种处理的土壤含水量、容重和氮、磷、钾、有机质含量以及玉米产量进行分析。结果表明,各处理在玉米拔节期、大喇叭口期、灌浆期和成熟期的土壤含水量由高到低的顺序均为:深翻>深松>常规耕作>免耕;深翻和深松处理0~30 cm,土壤容重较常规耕作分别降低10.27%和2.10%,免耕较常规耕作增加4.1%;深翻和深松处理较常规耕作的土壤速效钾、有效磷、有机质含量增加;深翻和深松处理的玉米产量分别较常规耕作提高20.38%和3.74%,免耕处理较常规耕作减产15.11%。选择合理的耕作方式,能够有效改善土壤结构,提高土壤含水量、有机质含量和作物产量。

关 键 词:耕作方式  土壤理化性状  土壤结构  玉米产量

Abstract:The effects of tillage treatments including deep ploughing,subsoiling tillage,no-tillage and conventional tillage to soil moisture content,bulk density and nitrogen,phosphorus,potassium,organic matter content and yield of maize were evaluated in this field experiments during 2010-2011.The results showed that the rank of soil moisture during jointing stage,grain-filling stage and mature period,from high to low were: deep ploughing,subsoiling tillage,conventional tillage,and no-tillage.The soil bulk density of deep ploughing and subsoiling tillage in 0~30 cm decreased by 10.27% and 2.10% as compared with conventional tillage.The soil bulk density of no-tillage in 0~30 cm increased by 4.1% as compared with conventional tillage.The soil available K,soil available P and the organic matter content of deep ploughing and subsoiling tillage increased compared with conventional tillage.The maize yields of deep ploughing and subsoiling tillage increased by 20.38% and 3.74% as compared with conventional tillage.The maize yield with no-tillage decreased by 15.11% as compared with conventional tillage.So,the reasonable tillage methods could improve soil structure,raise the soil water content,organic matter content and crop yields.
Keywords:tillage methods  soil physical and chemical properties  soil structure  maize yield
