| 摘要: |
| 为了建立宁夏惠农区庙台乡给予太阳能水泵抽水的暗管排水工程的灌溉排水制度，以油葵为研究对象，设暗管排水和非暗管排水2个处理，观测分析了暗管排水对田间土壤含盐量、地下水位和产量等的影响。结果表明，在油葵生育期内，与进行暗管排水前相比，暗管排水使暗管排水区的地下水水位降低0.09 m，降幅6.21%；地下水矿化度降低9.79%；土壤含盐量降低13.64%；与非暗管排水区相比，暗管排水区的油葵增产8.10%，灌溉水生产效率增加8.40%，群体水分生产效率增加9.86%。 |

| Abstract: |
| Taking oil sunflower as the model plant, we comparatively studied the impact of subsurface pipe drain and non-pip drain on soil desalination and water use efficiency of the plant. The experiment was conducted in Miaotai, Huinongin Ningxia and the drained water was pumped using solar-powered pumps. During the experiment, we measured soil salinity, change of groundwater table, as well as the yield. The results showed that, compared with non-pipe drain, in the area controlled by the subsurface pipe drain, the groundwater table dropped by 0.09 m, salt content in groundwater decreased by 9.79, soil salinity decreased by 13.64%, and the yield increased by 8.10%. In addition, it increased the water productivity by 8.40% and the water production efficiency by 9.86%. |
