喷灌可以在不同程度上实现自动化,但受投入及其他因素制约,我国目前全自动喷灌为数不多,大多是将劳动强度大、重复次数多的工作予以自动控制的半自动化喷灌。我省在90年代初也建成部分半自动喷灌试点,但总体看技术不成熟,稳定性差,实用性差,不便操作。1997年底,结合郑州市节水示范乡建设,中牟县引进灌溉自动控制设备,结合示范区实际又配套研制部分辅助装置,成功地建成了3处半自动控制喷灌试点,设备均采用美国雨鸟(RAIN BIRD)公司生产的系列产品。电器自动保护及管道过压保护装置则是我县根据自控设备工作原理自行研制装配的。
Sprinkler irrigation can be automated to varying degrees, but by the input and other factors, our country is currently one of the few automatic sprinkler irrigation, mostly labor-intensive, repetitive number of jobs to be automatically controlled semi-automatic sprinkler irrigation. In the early 1990s, our province also built some semi-automatic sprinkler irrigation pilot projects. However, overall the technology is immature, with poor stability and poor practicability, which makes it inconvenient to operate. The end of 1997, combined with the construction of water-saving demonstration townships in Zhengzhou City, Zhongmou County, the introduction of automatic control equipment for irrigation, combined with the actual demonstration area and supporting the development of some auxiliary devices, successfully built three semi-automatic control irrigation sprinkler pilot, the device uses the American Rain Bird BIRD) company’s products. Electrical automatic protection and pipeline over-voltage protection device is my county based on the working principle of self-control equipment to develop their own assembly.
