1978年轻工业部、水利部组织11省、市33个科研和生产单他,成立了移动式塑料喷灌设备全国联合设计组。经两年的工作,研究成功了两种五个系列移动式塑料喷灌管道和两种四个不同型号塑料喷头。1980年由两部组织进行了技术鉴定,同意定型,批量生产,两年来据不完全统计,全国各地共使用40～50万支PYS系列塑料喷头和几十万米塑料喷灌管道,经近几年生产使用,受到了用户欢迎。
In 1978, the Ministry of Light Industry and the Ministry of Water Resources organized 11 research and production projects in 11 provinces and municipalities and set up a national joint design team for mobile plastic sprinkler irrigation equipment. After two years of work, two types of five series of mobile plastic sprinkler pipes and two kinds of four different types of plastic sprinklers were successfully researched. In 1980, the two organizations conducted technical appraisals and agreed to stereotypes and mass production. According to incomplete statistics over the past two years, 40 to 500,000 PYS series plastic spray nozzles and hundreds of thousands of meters of plastic sprinkler pipes were used throughout the country. In recent years Production use, has been welcomed by users.
