灌水技术是在田间实现合理、有效灌溉的关键,随着喷滴灌新技术的发展,雾灌是近几年来新发展的一种灌水技术,已引起各有关方面的重视。国外试验表明,雾灌不仅可以浇灌花草和一些经济作物,而且也可以用来防寒潮霜冻害和夏季抗干热害。目前国内尚处于研制试验初期,82年水电部、中国农科院农田灌溉研究所滴灌组研制出单向和双向两种低压雾化微型塑料喷头,这种喷头可以安装在低压滴灌管道系统上即可实现喷雾灌溉。一年来经在海南岛、广州、杭州、河南信阳、南阳等地进行雾灌喷洒示范,
Irrigation technology is the key to achieve reasonable and effective irrigation in the field. With the development of new technology of drip irrigation, fog irrigation is a newly developed irrigation technology in recent years, which has aroused the attention of all parties concerned. Foreign experiments show that fog irrigation can not only watering flowers and some cash crops, but also can be used to prevent cold frost damage and summer dry heat damage. At present, China is still in the early stages of research and development. In 1982, the Ministry of Water and Electricity and the Institute of Farmland Irrigation, Chinese Academy of Agricultural Sciences, developed two kinds of low-pressure atomized mini plastic spray heads, one-way and two-way. These spray heads can be installed on low pressure drip irrigation pipelines Spray irrigation can be achieved. Year after year in Hainan Island, Guangzhou, Hangzhou, Henan Xinyang, Nanyang and other places fog irrigation demonstration,
