不同地下水埋深下冬小麦和春玉米非充分灌溉制度研究

Study on Insufficient Irrigation Schedule of Winter Wheat and Spring Maize under Different Groundwater Depth

根据山西省中心灌溉试验站多年灌溉试验资料,首先,分析计算无地下水的条件下(地下水埋深>3.0m)冬小麦和春玉米的经济灌溉定额,在此基础上,参考当地作物关键灌水期、地下水补给量及降水等试验资料,进一步确定两种作物在6种不同地下水埋深条件下不同水文年型的非充分灌溉制度。研究结果可为当地农业实际生产提供参考,具有较高的实际应用价值。

According to the experimental data for many years of center irrigation experimental station in Shanxi Province, firstly, the economic irrigation quota of winter wheat and spring maize are calculated and analyzed without groundwater conditions （groundwater depth〉 3. 0 m）. Based on it , referring to the experimental data of precipitation, groundwater contribution and key irrigation times of local crops, the insufficient irrigation schedule of two kinds of crops under six kinds of groundwater depth and different hydrological year are further determined. The results can provide reference for the actual production of local agriculture.
