For the application of PVC lay flat hose, the first one is the high water utilization coefficient. For the use of PVC lay flat hose, there is actually a set of special pipes to export water. In the process of water conveyance, there is almost no leakage and seepage, so it can be said that its water utilization coefficient is high. In addition, for the application of PVC lay flat hose, it can control the amount of water spraying, make the distribution of water spraying more uniform, and completely avoid the loss of surface runoff and deep leakage. Water productivity is high, real-time water supply can be achieved, crop ineffective transpiration and evaporation can be reduced, and waste can be avoided at the same time.
