| 摘 要： | 在四川丘陵区水旱轮作田进行了保护性耕作与传统耕作栽培模式的对比研究,对秸秆还田条件下的不同耕作模式对土壤水分及小麦产量的影响进行了探讨.试验结果表明,在小麦整个生育期,覆盖处理土壤水分含量均明显地高于不覆盖处理(对照),且免耕覆盖处理又显著优于翻耕覆盖处理.小麦分蘖高峰期覆盖处理的土壤水分比不覆盖处理分别高4.9%～12.8%,对土壤有较好的保墒作用.覆盖处理的小麦最高茎蘖数比翻耕不覆盖增加11.4%～45.8%,由于增加了小麦成穗数、穗粒数和千粒重,保护性耕作条件下覆盖处理比翻耕覆盖增产3.2%～18.1%,对提高小麦产量有明显的作用.

| Abstract: | The influence of different farming patterns on soil moisture and wheat yield in rotation paddy-upland crop field of Sichuan hilly area was investigated by comparing conservational farming method of straw covering with traditional farming method of non-straw covering.The results showed that the straw covering farming method increased markedly soil water content compared with the traditional farming method(ck),and the non-tillage straw covering farming method especially overmatched the tillage straw/non-straw... |
