淮北平原浅层地下水埋深影响旱作物生长的试验

为确定旱作物在生育期内利用浅层地下水的规律，减少旱作物的灌溉频次和灌溉量，提高农业节水效率，在淮北平原五道沟水文水资源实验站进行了浅层地下水埋深对旱作物生长影响试验，对比分析了淮北平原两种典型土壤（砂礓黑土和黄潮土）种植小麦和大豆两种旱作物时利用浅层地下水的程度的规律，从而确定这两种土壤在小麦和大豆生长期的地下水适宜埋深。结果表明，旱作物的生长过程与利用浅层潜水位关系复杂，且不同土壤类型、不同作物存在最佳的地下水埋深。

Experimental Study on Utilization of Groundwater for Drought Crops in Huaibei Plain

To determine the groundwater utilization of drought crops in the reproductive period, reduce the irrigation frequency and amount of irrigation for drought crops, improve the efficiency of agricultural water conservation, experiments on how groundwater depth influenced drought crops in the reproductive period were carried out at Wudaogou hydrology and water resources experiment station in Huaibei Plain. The laws of groundwater utilization were analyzed when wheat and soybeans were planted in two typical soils (black soil and sand Jiang Huang Chao soil) in order to determine the optimal depths. The result shows that there is complex relationships between the growth of drought crops and the shallow groundwater control depth, and for different soil types or different crops, there are optimal groundwater depth.
