结合地上滴灌与渗灌技术优势，提出并进行了地下低压微孔管灌技术要素试验研究，结果认为，条件许可的地方工作压力选择１．５７～２．３５ ｋＰａ 变水头，管径２０ ｍ ｍ ，孔距６０ ｃｍ ，孔径０．７ ｍ ｍ 为最佳管道技术要素；微孔管内的悬浮物质及固体物质易于清洗；管道各孔口出流均匀，土壤湿润理想；并可方便施肥 According to the technical advantages of aboveground drip irrigation and seepage irrigation, the experimental research on the underground low pressure microporous tube irrigation technology was proposed and carried out. The results show that the local working pressure is 1.57-2.35 kPa variable head with the diameter of 20 m , With a hole distance of 60 cm and a pore diameter of 0.7 m m are the best technical elements of the pipeline. Suspended matter and solid matter in the microporous tube are easy to clean; the outlet of the pipeline is uniform and the soil is moist and ideal;
