Different irrigation models have their own advantages and disadvantages, to adjust measures to local conditions into account. Disc artificial mobile sprinkler sprinkler and hose volume is suitable for China's national conditions. 2 it is underground irrigation has been recognized as a most promising high efficient water-saving irrigation technology. Although there are some problems at the moment, the application promotion speed is slow, but as the solution of the key technologies, will get a certain development in the future. Three is the surface irrigation is still the world's dominant irrigation technology. With the mature of efficient field irrigation technology, ShuPeiShui low-pressure pipelining the trend of the development of the direction. Four is agricultural efficient water saving irrigation technology management level is higher and higher. Application of expert system, computer network technology, control technology resources database, the simulation model of integration, to achieve, empty, quantity, quality, and the precision irrigation, is the focus of future research. 三、發(fā)展節(jié)水灌溉技術(shù)的政策建議 Third, policy Suggestions of developing water-saving irrigation technology 　　 　　一是提高發(fā)展節(jié)水灌溉技術(shù)的認(rèn)識(shí)。我國是一個(gè)水資源短缺的國家，隨著人口增加、經(jīng)濟(jì)發(fā)展、社會(huì)進(jìn)步，農(nóng)業(yè)灌溉用水要在用水總量基本不增加的情況下保障我國糧食安全，只能走內(nèi)涵式發(fā)展的道路，灌溉必須走節(jié)水型的發(fā)展道路。因此，我們應(yīng)加大對(duì)發(fā)發(fā)展節(jié)水灌溉技術(shù)的宣傳教育力度，使全社會(huì)都來關(guān)心節(jié)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 water 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 society 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)普及與推廣噴、微灌技術(shù)。在節(jié)水灌溉模式中，噴、微灌應(yīng)用越來越多，目前國內(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. One is adjust measures to local conditions, continue to spray, micro-irrigation technology popularization and promotion. In water-saving irrigation mode, and microspray irrigation is used more and more, spray, micro-irrigation technology at home and abroad are moving in low pressure, energy-saving, multipurpose utilization, automation of product standardization, seriation and operation direction. Second, the irrigation canal system pipelining. Our country has been basically popularized the area of low pressure pipeline technology, the future development direction is a large canal irrigation canal system pipelining, and accelerate the development of corresponding large-diameter plastic pipe material production. 　　三是現(xiàn)代精細(xì)地面灌溉技術(shù)。由于我國地面灌溉量大、面廣，需要采用推廣應(yīng)用激光控制平地技術(shù)、水平畦田灌溉技術(shù)、田問閘管灌溉系統(tǒng)以及土壤墑情自動(dòng)監(jiān)測(cè)技術(shù)等一切改進(jìn)地面灌溉措施，逐步實(shí)現(xiàn) 田間灌溉水的有效控制和適時(shí)適量的精細(xì)灌溉 。 Three is the modern fine ground irrigation technology. 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 technology, 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)。非充分灌溉理論將與生物技術(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)水中的應(yīng)用。如果能在農(nóng)業(yè)節(jié)水中推廣應(yīng)用“3S”技術(shù)產(chǎn)生的節(jié)水效能將是革命性的。 此外，國外還 出現(xiàn) 了地面浸潤灌溉、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)我國的節(jié)水灌溉有積極的參考借鑒意義。 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. Non full irrigation theory and biotechnology, information technology and the transformation of "four water" and other high and new water-saving technology and theory, combining to create a new system of irrigation theory and technology. Five is the application of "3 s" technology in agricultural water saving. If we can application in agricultural water saving water-saving efficiency of "3 s" technology is revolutionary. Abroad also appeared the ground slope infiltration irrigation, irrigation pipe irrigation, soil net irrigation, rope control irrigation and new water-saving irrigation techniques, both for China's water-saving irrigation has positive reference significance. In desert areas and the lack of fresh water in coastal areas, the use of the moisture in the air for irrigation is a desirable method, but how to reduce costs, improve efficiency and practicability is the problem to be solved in the future. To sum up, promoting water-saving irrigation project, a long way to go. We have reason to believe that, through the gradually promote the use of water-saving irrigation, realize the scientific development of the water resources, to achieve the sustainable utilization of water resources. Just around the corner.
