雾灌是雾化灌溉的简称,是近年来新兴的一种灌水技术。它兼备了喷、滴灌技术之长,避其二者之短。雾灌工作压力低(100千帕左右),比喷灌更为省水节能,一般能比喷灌省水30%左右,比地面灌省水70%以上,投资和运行费用比固定式喷灌约低一半。比滴灌抗堵塞,供水快,适应性强。特别在干旱高温期间,雾灌可使作物叶面温度降低3—5℃,株间相对湿度提高30%,能缓解高温、低湿对作物产生的不良影响,促进光合作用,适于多种经济作物的灌溉,增产效益显著。雾灌在我国的发展始于八十年代初。我们在认真
Fog irrigation is the abbreviation of atomized irrigation, is a new emerging irrigation technology in recent years. It combines the spray, drip irrigation technology, avoid the short of both. Fog irrigation work pressure is low (about 100 kPa), more sprinkler than water saving and energy saving, generally can sprinkler irrigation water is about 30% more than the ground irrigation water more than 70%, investment and operation costs about half lower than fixed sprinkler irrigation . Anti-blocking than drip irrigation, water supply, adaptability. Especially in the period of drought and high temperature, fog irrigation can reduce the leaf temperature of crops by 3-5 ℃ and the relative humidity between plants by 30%, which can alleviate the adverse effects of high temperature and low humidity on crops and promote photosynthesis, which is suitable for many kinds of cash crops Irrigation, yield significant benefits. Fog irrigation in our country started in the early eighties. We are serious
