| 摘 要： | 保护性耕作是农业生产的一项重要技术措施。以玉米(东单60)为材料进行秸秆覆盖试验,探讨了保护性耕作对玉米生长和产量以及田间耗水量的影响。采用SPSS软件对实测数据进行分析,结果表明:保护性耕作节水保肥和提高水分利用效率等方面均优于传统耕作,免耕覆盖对耕层土壤含水率影响显著,而浅耕覆盖对土壤耕层养分和作物生长及产量影响显著,水分利用效率最高。

| Abstract: | Conservation tillage techniques have become the most measures of agriculture development.This article through experiment on corn straw mulching explore conservation tillage effect on maintenance capacity of water-fertilizer,water consumption and yield.The experiment data was analysis by SPSS.The result showed conservation tillage was better than traditional cultivation not only on maintenance capacity of water-fertilizer in surface soil but also on moisture using efficiency effect on moisture,zero-tillage c... |
