| 摘 要： | 为了研究冬小麦地下水埋深与产量的关系,以地下水的降落速度与适宜埋深作为冬小麦排水的调控指标,在蒸渗测坑内进行冬小麦水位调控试验,通过理论分析和数值计算,建立了排水条件下冬小麦水位生产函数；考虑到根层土壤含水量与地下水位的耦合作用对冬小麦产量的影响,提出了用土壤含水量作为修正系数的控制排水条件下冬小麦的水位生产函数.函数... |

| Abstract: | In order to investigate the relationship between the groundwater depth and yield of winter wheat,a water level control test on the winter wheat was carried out in evaporation-infiltration test pits,based on control indices including the descending velocity and the suitable depth of the groundwater.Through theoretical analysis and numerical calculation,the water-level production function for the winter wheat under drainage conditions was developed.With consideration of the coupling effect of the root-soil wa... |
| Keywords: | winter wheat water-level production function correction of soil water content farmland drainage controlled drainage |
