摘要
在覆盖与耕作技术研究的基础上,分析了覆盖与耕作技术对水分利用效率,培肥地力,和作物产量产生的效应.明确了合理的覆盖与耕作技术的综合运用可以增加土壤水分利用效率,均衡利用土壤养分,可有效提高作物产量.
The effects of multching and tillaging technology on water use efficiency and on improving soil fertilety and on increasing crop yield were analyzed.This paper pointed that using proper mutching and tillaging technology could not only improve water use efficiency,but also utilize soil nutrient bal- ancedly,and also improve crop yield effectively.
