【摘要】In the test, internal inlay drip irrigation pipes with different wal thicknesses or diameters (￠at 12 mm and 16 mm) were tested under varying tension forces and it was concluded that 90 N is the rational one. What’s more, the smal er drip-irriga-tion inner diameter, the thinner wal thickness, and the higher tension force, the lower acceptability, and the larger drip-irrigation inner diameter, the thicker wal thickness, and the lower tension force, the higher acceptability. The causes were analyzed in the research, including manufacturing technique leading to disqualifica-tion and different specifications with the same demands on techniques, and inadap-tation to tension force at 130 N.%该文通过采集不同壁厚，管径分别为￠12 mm、￠16 mm的内镶式滴灌带，同时施加不同力值。试验表明，滴管带管径越小、壁厚越薄、力值越大，合格率越低；管径越大、壁厚越厚、力值越小，合格率相对越高。应该将试验拉力改为90 N较合理。并针对试验中的问题，分析了存在问题的原因。分别是由于生产工艺导致无法满足标准要求、规格不同，技术要求却一视同仁、标准要求130N拉力不适应。
