When buying drip irrigation tape, you should first check the certificate and specification model label of the drip irrigation tape. Appearance characteristics of drip irrigation tape: black, uniform color; smooth surface, no bubbles, no hanging lines, no dead blocks, no impurities; the labyrinth flow channel is fully formed and has no deformation. When buying drip irrigation tape, pay attention to the following indicators: the general drip irrigation tape flow rate is 1.8-3.0L/h, the dripper spacing is 300-400mm, the labyrinth drip irrigation tape flow index is 0.5-0.6, and the smaller the flow uniformity coefficient (CV), the less than 5%. In addition to meeting the above standards, you should also pay attention to the selection of drip irrigation tapes with serrated pipe structure, good tensile strength and aging resistance.

During use, inferior drip irrigation belts often leak, have uneven flow rates, cracks, burst pipes, etc. The overall performance is: insufficient tensile strength, the seed cloth is easy to break, affecting the sowing speed, increasing the cost of cloth and installation; the cloth is easy to age, crack or burst; the cloth is uneven, the cloth is uneven, the cloth is uneven, and the cotton yield per mu is more than 20kg of seed cotton due to uneven water and fertilizer; low operating pressure causes uneven cloth in the entire system, and the advantages of drip irrigation cannot be fully utilized; the water pump has low operating efficiency, which increases additional expenses.

In addition, when choosing a drip irrigation tape, you should pay attention to the ratio of new and old materials. Generally, the toughness of a drip irrigation tape with too high a ratio of old materials is poor. It can be easily supported or broken by using a expander, while the drip irrigation tape with more new materials has better compactness and toughness.

The spacing between different drip irrigation tapes and the stability of the flow rate will directly affect the amount of water and fertilizer applied, and thus affect the growth of cotton. In addition, when laying the drip irrigation tape, we must also be careful not to twist the drip irrigation tape off, so as to avoid dry pipes when dripping, and water and fertilizer cannot pass well.

When laying the drip tape, the maze should be facing up and down, so that the water pressure and water flow rate are consistent.

In short, "good quality and low price", Shandong Hengxiang Plastic Machinery Co., Ltd. reminds everyone: when buying drip irrigation tape, I hope everyone can strengthen their ability to distinguish and pay attention to the harm of inferior drip irrigation tape. Keep your eyes open, so that fakes have nowhere to hide, and safeguard your own interests.
