| 节水灌溉技术发展呈现以下趋势： The development trend of water-saving irrigation technology is as follows: （1）喷灌技术仍为大田农作物机械化节水灌溉的主要技术，其研究方向是进一步节能及综合利用。不同喷灌机型有各自的优缺点，要因地制宜综合考虑。绞盘式喷灌机及管道移动式喷灌比较适合我国国情。 (1) Sprinkler irrigation technology is still the main technology of mechanized water-saving irrigation for field crops, and its research direction is to further save energy and comprehensive utilization. Different types of sprinkler irrigation machines have their own advantages and disadvantages, which should be considered comprehensively according to local conditions. Winch sprinkler and pipeline mobile sprinkler irrigation are more suitable for China's national conditions. （2）地下灌溉已被世人公认是一种最有发展前景的高效节水灌溉技术。尽管目前还存在一些问题，应用推广速度 较慢，但随着关键技术的解决，今后将会得到一定的发展。 (2) Underground irrigation has been recognized as one of the most promising and efficient water-saving irrigation technologies. Although there are still some problems and the speed of application and popularization is slow, with the solution of key technologies, it will get some development in the future. （3）地面灌溉仍是当今世界占主导地位的灌水技术。随着高效田间灌水技术的成熟，输配水有低压管道化方向发展的趋势。 (3) Surface irrigation is still the dominant irrigation technology in the world today. With the maturity of high-efficiency field irrigation technology, there is a trend of low-pressure pipelining for water transportation and distribution. （4）农业高效节水灌溉技术管理水平越来越高。应用专家系统、计算机网络技术、控制技术资源数据库、模拟模型等技术的集成，达到时，空、量、质上的精确灌水，是今后攻关的重点。 (4) The management level of agricultural high-efficiency water-saving irrigation technology is getting higher and higher. The integration of expert system, computer network technology, control technology resource database, simulation model and other technologies to achieve precise irrigation in time, space, quantity and quality is the focus of future research. （5）节水综合技术的开发利用，是提高水分利用率和水分利用效率的重要途径，也是今后节水灌溉发展的方向。 (5) The development and utilization of water-saving comprehensive technology is an important way to improve water use efficiency and water use efficiency, and is also the direction of water-saving irrigation development in the future. （6）节水灌溉新技术： (6) New water-saving irrigation technologies: 滴灌、膜下滴灌、中心支轴式喷灌、平移式喷灌、微喷灌等都是灌溉水利用系数较高的灌溉形式，其中滴灌、膜下滴灌在我国部分地区技术已成型。 Drip irrigation, drip irrigation under mulch, Central Branch sprinkler irrigation, translational sprinkler irrigation and micro-sprinkler irrigation are all irrigation forms with high utilization coefficient of irrigation water, among which drip irrigation and drip irrigation under mulch have been formed in some areas of China. |
