Comparative Test of Anti Clogging Performance of Runner Drop Head for 3 Kinds of Drip Tape

Comparative test of anti clogging performance of runner drop head for 3 different kinds of drip tape was carried out.Test results showed that anti clogging performance of new flow channel structure with interior inlay paster drip tape increased by more than 30% than side seam type drip irrigation belt，and increased by more than 1 time than conventional inner insert patch type drip irrigation tape.New flow channel structure with interior inlay paster drip tape not only solved the problem of irrigation uniformity difference for side seam type drip irrigation belt，but also made up shortcomings of easy blocking for conventional inner insert patch type drip irrigation tape.And its popularization and application prospect was broad.
