Ⅱ 、Overview of agricultural irrigation
(1) Field crops mechanized sprinkler technology is still a major water-saving irrigation techniques.
Different sprinkler models have their advantages and disadvantages, to local conditions into account. Hose reel irrigation machine and manually move the sprinkler is suitable for China's national conditions.
(2) Underground irrigation has been recognized as one of the most promising and efficient water-saving irrigation technology.
Although there are still some problems, promote the application slower, but with the key technology to solve the future will be a certain degree
(3) Surface irrigation is still the world's dominant irrigation techniques.
As technologies mature and efficient field irrigation, water distribution pipeline in the direction of the development of the low-pressure trend.
(4) Agriculture and efficient water-saving irrigation technology management level is increasing.
Application of expert systems, computer network technology, control technology resource database integration, simulation models and other techniques reached, empty volume, precision irrigation on quality, focus on the future of public relations.
(5) Water-saving integrated technology.
The development and utilization of water-saving integrated technology is to improve water use efficiency and water use efficiency in important ways, but also the future direction of the development of water-saving irrigation.
