Using the Test of Uniformity Degree of Watering to Determine Technical Parameters of Subirrigation

QIN Yong-guo WANG Jian-jun YAN Xiao-na ZHU Xiao-xia  
Aimed at the existing technical problems in developing subirrigation on a large scale area in Yun cheng City in the early days of 1990s,the test of uniformity degree of watering through infiltration pipe was carried out in Jiamakou Irrigation District.Through test and research,the technical parameters of subirrigation suited to practical situation in situ are determined :the length of subirrigation infiltration pipe must be less than 95m,the centre distance of pipe less than 1.2m and the centre distance of infiltration hole less than 0.6m.These parameters provide planning and design basis for the future construction of subirrigation project in this city and will take important effect to promote healthy development of this technique.
