摘　　要：在成层土上畦灌非恒定流模型及其数值解的基础上，结合灌区实际，优化出小麦不同生育阶段在不同坡度下的灌水技术参数的组合．通过大田试验和推广应用，节水增产效果显著。On the basis of unsteady flow of border irrigation and numerical solution, and with consideration of practice of irrigation districts, optimized combination of technical parameters of border irrigation for different crop growing seasens of wheat on different slopes of farmland is made. Experiments and applications have shown high efficiency of water saving. The results obtained can be used in water saving irrigation and water management.
