Abstract
It is known that, in our country, the current situation of water for farmland irrigation is low utilization, lack of management and a large number of serious water wastes. Therefore, the development of agricultural water-saving irrigation technology has become a top priority. According to the statistics survey of National Water Resources Development Ministry which published by Water Resources Bulletin, from 2000 to 2012, this paper analyzes the Chinese investment trend on water-saving irrigation, as well as the changeable situation of effective irrigation area. The results show that, during statistical periods, our country has paid attention to irrigation work and increased emphasis policy on agriculture. On this occasion, the irrigation investment increased 6 times and the promotion area increased by 14%. We can even draw a conclusion that China has promoted the development of agricultural water conservation work effectively. Moreover, in view of the existing multiple saving irrigation methods, this manuscript also analyzes the advantages and disadvantages in practical application, respectively. Putting forward the simulative suggestions to promote the water-saving irrigation technology and equipment provides a theoretical basis for future water-saving irrigation.
