摘　　要：以冬小麦夏玉米为代表作物,从雨养、旱作及补充灌溉3方面出发,探讨了河北太行山山前平原区实施半旱地农业的可行性。结果表明,在河北太行山山前平原降水量400mm左右的冬小麦夏玉米种植区,充分发挥作物自身抗旱耐旱特性,通过减少无效蒸发量,在作物生长关键时期补充一定的灌水量,基本能满足作物对水分的需求,维持正常产量和较高的水分利用效率。山前平原区实施半旱地农业,在运用旱作技术充分利用自然降水的基础上进行少量水补充灌溉,大量减少农业灌溉用水,在理论和实践上应该是可行的,值得进一步探索和实践。Taking the winter wheat and summer maize for representative crops, we discuss the feasibility of implementing semi-dryland farming, which is composed of rainfed, dry farming techniques and supplemental irrigation, on piedmont of Taihang Mountain. The results show that in the winter wheat and summer maize growing areas of Taihang Piedmont, where the rainfall is about 400 mm, some supplementary irrigation could basically meet the crop water requirement and keep the normal grain yields and a much higher WUE, which is based on the properties of crop drought resistance and decreasing the invalid evaporation. And it is feasible to reduce the agriculture irrigation water in the piedmont region of Taihang Mountain in theory and in practice, which is based on the full utilization of rainfall and supplement irrigation, and it is also worthy of further exploration and practice.
