一、前言在国外许多喷滴灌系统,尤其是固定管道式喷滴灌系统,多采用自动控制,许多工厂成套生产自动化喷灌设备。我国的江苏、武汉、江西、山西、北京、上海等地相继开展了自动化喷滴灌的试验研究,建立了一批自动喷灌站。根据试验研究证明,采用自动化喷滴灌,能够根据作物的需水要求,适时、适量地灌 I. Introduction In many foreign countries, drip irrigation systems, especially fixed-pipe drip irrigation systems, use automatic control and many factories produce complete sets of automated sprinkler irrigation equipment. China’s Jiangsu, Wuhan, Jiangxi, Shanxi, Beijing, Shanghai and other places have carried out pilot tests of automated spray drip irrigation, the establishment of a number of automatic irrigation stations. According to the experimental study shows that the use of automated spray drip irrigation, according to the crop’s water requirements, timely and appropriate irrigation
