26、水灌溉技術(shù)， 形成好 的節(jié)水灌溉技術(shù)發(fā)展環(huán)境。One is to improve the understanding of the development of water-saving irrigation technology. China is a country with a shortage of water resources, as the population increases, economic development, social progress and agricultural irrigation HYPERLINK / / HYPERLINK / /water

27、to total water basic without increasing safeguard food security in China, only to the road of connotative development, must be on the development road of water-saving irrigation. Therefore, we should step up publicity and education of development water saving irrigation technology, make the whole so

28、ciety to care about water saving irrigation technology, form good water-saving irrigation technology development environment.二是節(jié)水灌溉技術(shù)發(fā)展要符合農(nóng)村實(shí)際。 一是因地制宜， 繼續(xù)普 及和推廣噴、 微灌技術(shù)。在節(jié)水灌溉模式中， 噴、微灌使用越來(lái)越多， 目前國(guó)內(nèi)外噴、微灌技術(shù)正朝著低壓、節(jié)能、多目標(biāo)利用、產(chǎn)品標(biāo)準(zhǔn) 化、系列化及運(yùn)行管理 自動(dòng)化方向發(fā)展。二是灌溉渠系管道化。我 國(guó)已基本普及了井灌區(qū)低壓管道輸水技術(shù) ，今后的發(fā)展方向是大型 渠灌區(qū)渠系管道化，并加快相應(yīng)大口徑

29、塑料管材的開發(fā)生產(chǎn)。2 it is to conform to the rural practical water-saving irrigation technology development.

Due to the large amount of surface irrigation and surface broad, application need to be adopted to control the ground laser technology, horizontal border check irrigation technolog

33、y, tian asked brake pipe irrigation and soil moisture all improved surface irrigation measures such as automatic monitoring technology, and gradually achieve the effective control of the field irrigation water and timely proper irrigation.四是研究和推廣非充分灌溉技術(shù)。非充分灌溉理論將和生物技 術(shù)、信息技術(shù)及 “四水 ”轉(zhuǎn)化理論等高新節(jié)水技術(shù)和理論相結(jié)合，創(chuàng)建

34、 新的灌溉理論及技術(shù)體系。 五是 “3S”技術(shù)在農(nóng)業(yè)節(jié)水中的使用。 如果 能在農(nóng)業(yè)節(jié)水中推廣使用 “3S”技術(shù)產(chǎn)生的節(jié)水效能將是革命性的。 此外，國(guó)外還 出現(xiàn) 了地面浸潤(rùn)灌溉、 坡地灌水管灌溉、 土壤網(wǎng)灌溉、 繩索控制灌溉等新的節(jié)水灌溉技術(shù)， 都對(duì)我國(guó)的節(jié)水灌溉有積極的參 HYPERLINK / / HYPERLINK / /考借鑒意義。 對(duì)于沙漠地區(qū)和缺乏淡水的沿海地區(qū)，利用空氣中的 水分進(jìn)行灌溉是一種可取的方法， 但如何降低成本， 提高效率和實(shí)用 性是今后應(yīng)著重解決的問題?？偠灾?，節(jié)水灌溉工程推廣，任重而 道遠(yuǎn)。我們有理由相信，通過節(jié)水灌溉的逐步推廣使用，實(shí)現(xiàn)水資源 的科學(xué)開發(fā)，實(shí)現(xiàn)水資源的可持續(xù)利用，指日可待。Four is the study and promotion of non sufficient irrigation technology.
