摘要
系统地研究了宁夏半湿润偏旱区农田水分动态变化规律,全面分析了本地区农田水分与农田地力的关系,认为地力不足是农田水分利用效率低的重要因子,并相应地提出了开发农田水分生产潜力的途径.
This article systematically introduces the changing regularity of farmland moisture movement and also analyses the relation of farmland moisture to farmland soil productivity in a comprehensive way. The analysis shows that the shortage of soil productivity is the main factor which causes low efficiency in farmland moisture utilization and the relevant way how to develop the production notentials of farmland moisture is suggested.
