摘　　要：本文对已有的浅井工程进行抽水试验、灌溉试验 ,经过理论分析 ,推导出了单井低压管道输水灌溉系统的最优出水量、最佳降深、最佳扬程、经济管径及田间多孔软管配水计算方法 ,确定了浅井灌溉费用最小。On the basis of pumping test, irrigation test and theory analysis a method for calculating the irrigation soft pipe in low pressure irrigation system having reasonable yield of well, reasonable decent of water table, best pumping head and economical diameter is proposed. By this method the optimized irrigation system with highest benefit and lowest cost is derived.
