上海市喷灌技术推广工作,起始于一九五四年,经过较长时间的反复。近三年来边试点,边推广,至今,以近郊二十七个重点蔬菜公社为重点,同时包括本市郊区十个县,十七个农场、有关园林苗圃,已发展喷灌面积八万余亩,其中多数采用移动式小型电动喷灌机组,也有少数固定和半固定喷灌系统。郊县社队对喷灌的态度,也有一个观望——怀疑——试试——信任——主动要求的过程。主要原因是近几年来喷灌设备在质量上有较大的进步,使用喷灌能提高工作效率;其次是蔬菜喷灌的经济效果明显。
Sprinkler irrigation technology in Shanghai to promote the work started in 1954, after a long period of repetition. In the past three years, we have piloted and piloted the project. To date, we have focused on 27 key vegetable communes in the suburbs, including ten counties and 17 farms in the outskirts of the city, and related garden nurseries. We have developed more than 80,000 hectares of sprinkler irrigation area, Most of them using mobile small electric sprinkler, there are a small number of fixed and semi-fixed sprinkler system. Suburban communes and sprinklers on the attitude, there is a wait and see - doubt - try - trust - the process of the initiative requirements. The main reason is that in recent years, the quality of sprinkler irrigation equipment has been greatly improved, the use of sprinkler irrigation can improve work efficiency; followed by the economic effect of sprinkler irrigation is obvious.
