| 摘 要： | 采用3种稻田保护性耕作栽培模式与传统栽培模式的定位试验,对成都平原稻田小麦季的土壤水分及产量进行了研究。结果表明:小麦全生育期,免耕覆盖处理的土壤含水率明显地高于翻耕覆盖处理,而翻耕不覆盖处理最差;小麦分蘖高峰期,覆盖处理的土壤含水率比不覆盖处理高17.7%～75.9%,免耕覆盖处理的土壤含水率比翻耕覆盖处理高12.7%～41.0%;免耕覆盖处理的小麦最高茎蘖数又比翻耕覆盖处理增加23.8%～72.3%,均极显著优于翻耕处理;覆盖处理的小麦产量比不覆盖处理增产6.3%～19.5%,免耕覆盖处理比翻耕覆盖处理增产3.2%～8.0%。稻田保护性耕作有利于提高成都平原区小麦产量。

| Abstract: | The soil moisture and wheat yields in paddy field of Chengdu plain area during the wheat season were investigated by the location tests for three different kinds of conservation tillage and conventional tillage.The results showed that during the whole growth period of wheat,the non-tillage straw covering farming method increased markedly soil water content than the tillage straw covering farming method,and the soil water content in the tillage non-straw covering farming treatment was the lowest.At the peak ... |
