薄壁双上孔滴灌带,是一种专门用于大棚、温室及小面积露地栽培的灌水器,它与主管、阀门、管件和有压力的水源一起组成滴灌系统,由于节水灌溉技术的推广,灌水器的种类越来越多,而这一新型滴灌带问世仅2年,就普遍替代了原有滴灌带,在北京市已经推广40余万米。该产品与一般滴灌带的不同之处,在于出水孔的分布方式。原来的滴灌带铺放在田间时,出水孔是双孔,上下方向各一个。而薄壁双上孔滴灌带,是每隔一定间距有一排两个全部朝上的孔,贴地一面无孔。这样,在田间使用时,其抗堵塞性能就大大优于原来的滴灌带。中国农业工程研究设计院研制出机械化自动打孔装置,从而使这种新产品批量生产,投放市场。
The thin-walled double-hole drip tape is a kind of drip irrigation system which is specially used for greenhouses, greenhouses and small-area open-field cultivation. It forms drip irrigation systems together with supervisors, valves, fittings and pressured water sources. Due to popularization of water- More and more types of devices, and this new drip belt advent of only 2 years to replace the original drip irrigation, in Beijing has been promoted more than 40 million meters. The difference between this product and ordinary drip tape lies in the distribution of the water outlet. The original drip tape shop in the field, the outlet is double hole, up and down one each. The thin-walled double-hole drip irrigation, there is a row at a certain interval of two rows of two all up the hole, stick to one side without holes. In this way, when used in the field, its anti-clogging performance is much better than the original drip tape. China Agricultural Engineering Research and Design Institute developed a mechanized automatic drilling device, so that this new product mass production, put on the market.
