Characteristics and indexes of water distribution of punched thin-soft tape for spray

As a new irrigation system, the punched thin-soft tape for spray which is made of plastic has been widely used in China since 1990. According to the irrigation characteristics of the tape, a special device was designed to measure the water distribution of the tape on the ground, and then the indexes of describing the water distribution were established on the basis of the test results. The test results are original datum material and information for design, production and application of the tape.
