摘要 根据巩县和泰安4年小麦水分试验资料,分析确定了冬小麦最佳耗水量。从充分利用自然降水和土壤贮水角度出发,分析了影响麦田水分状况的各种因子,得出全生育期水分供需差。进而根据小麦阶段耗水的差异和麦田水分动态分析,确定了小麦适宜灌溉期。在上述基础上得出该区小麦优化灌溉方案,通过大面积推广应用,证明该方案可行,具有重大经济效益。 According to the analysis of water experimental data of winter wheat in Gong County and Taian City for 4 years optimal water consumption was defined. Each factors affecting water condition of wheat field were analyzed from points of making full use of natural precipitation and soil water storage, and water difference between supply and demand during whole growing season was obtained. Suitable irrigation times were defined according to difference of water consumption between different stages and dynamic analysis of wheat field water. For the above-mentioned results wheat optimal irrigation program in region of Beijing Tianjin Hebei Shandong Henan in normal climatic program year was given. Results of extend application in wide area indicated that the is feasible and has higher ecnomic benefit.
