A new type of microporous infiltrating pipe, which integrates water-saving, energy-saving, anti-blocking, and low cost advantages, was successfully developed at Pengyuan Plastic Products Co., Ltd., Jiyuan City, Henan Province. After drip irrigation trials in Daejeon, greenhouse vegetables, and orchards, the effect is very good. This technology has passed the identification. Microporous infiltrating pipe is mainly made of polyethylene and rubber. The wall of water infiltrating pipe is composed of three parts: protective layer, drainage layer and water infiltration layer. The smooth surface of the tube is actually covered with numerous tiny holes that are invisible to the naked eye. As long as the water pressure is low (the water level is 1m high), it can be formed as human skin. "Italian irrigation - seepage irrigation. According to comparison, the pressure of the tube is 1/10 and the price is equivalent to 1/8 of that of the US product. Many trials have shown that the product has the following advantages: First, good anti-clogging performance; second, saving water resources, improving water utilization, saving 50% to 80% of water compared to furrow irrigation, and saving 40% of water compared to irrigation; Low pressure, saving energy. Compared with flood irrigation, it can save energy by 70%-80%, saving energy by 60%-83% compared to sprinkler irrigation. Fourth, it has good irrigation effect and obvious effect of increasing production. According to the test, the yield of cucumber in the infiltration irrigation greenhouse was increased by an average of 67% or more. The introduction of new microporous infiltration pipes has been favored by farmers, and it has been applied in Beijing, Guangdong, Shandong, Shanxi, Jilin, Gansu, and Henan. A total of 1.5 million m micro-permeability tubes have been tested. (Tao Weimin Anhui Institute of Agricultural Machinery 230031)
