| 摘 要： | 通过长期定位试验，研究了宁夏半湿润偏旱区农田水分运动规律、主要作物对农田水分的利用、水分对作物生长的影响以及降水资源的利用。结果表明，春小麦水分入不敷出，干旱缺水及降水的季节变化是该区农业生产的主要限制因子，作物水分利用效率低影响了降水生产潜力的发挥，因而开发降水生产潜力是提高该区农业生产力的关键。

| Abstract: | The soil water movement law of farmland ,water utilization situation of main crops ,water regime affecting crops growth and utilization of rainfall resources were analyzed. It is thought that the dry and water deprivation restricted agricultural production in half-humid inclined to dry areas of Ningxia. Developing the production potentiality of rainfall and increasing the water use effeciency of crops in the areas are key measures to improve agricultural productivities. |
