不同潜水埋深条件下蒸发蒸腾试验研究

STUDT OF EVAPOTRANSPIRATION TEST ON THE CONDITIONS OF DIFFERENT DEPTHS OF GROUNDWATER LEVEL

在天山北麓昌吉地下水均衡试验场 ,选择具有代表性的作物冬小麦进行模拟种植试验。观测不同生育期冬小麦耗水量 ,分析了潜水埋深对作物耗水的影响。研究成果对于地下水资源评价、土壤水资源时空调控利用。

In the groundwater experiment station at the northern piedmont of Tianshan,the representative crop winter wheat is selected to conduct the simulation planting test. The water consumptions of winter wheat at different growth period are observed,and the influence of groundwater deptbs on the water consumption of the crop is analyzed.The study result possesscs practical significance for the groundwater resource assessment, the soil-water resource space-time manipulation and utilization,agricultural saving on water, and the high and steady grain production.
