In recent years, southwest, northwest and northeast regions of China in drought-prone retransmission. In China, less water-saving irrigation area, less efficient water-saving irrigation area of ??accounting, but also increased the drought. Up to now, 900 million mu of effective irrigation area, and water-saving irrigation project area is only 45%, micro-irrigation, sprinkler irrigation, such as efficient water-saving irrigation area is only 8%, and unbalanced regional development, agricultural water use efficiency It is not high. And relative water shortage is seriously lagging behind the development of China's water-saving irrigation. At present China's agricultural water-saving irrigation is a big gap with foreign advanced water saving irrigation technology occupancy area, modernization of water-saving irrigation technologies are behind the developed countries, the technology system, there is a big challenge to promote ways. Farmers own limited financial resources, lack of investment in the central and local matching funds, moreover farmers with water for light weight water-saving ideas is difficult to change, plus backward technology and agricultural water management of the network and other factors are limiting the development of water-saving irrigation industry. Total water and agricultural water use remained stable in our society, including agricultural water use social largest proportion of the total water consumption. As of 2013, China's total water consumption is 617 billion cubic meters society, of which 390 billion cubic meters of the total agricultural water use, accounting for 63.2% of total water consumption proportion of society, the largest proportion. Since agricultural water use accounts for the largest total water proportion society, agricultural water-saving irrigation has become increasingly subject to the attention of the State and relevant ministries, government investment will increase their own efforts to promote the development of agricultural water-saving irrigation industry. In addition, the drought-prone also look to the government to put more water-saving irrigation of farmland water conservancy construction. Recently, the Ministry of Water Resources, the National Development and Reform Commission, Ministry of Finance, the Ministry of Agriculture jointly issued the "National Drought planning and implementation of the program (2014- 2016)" (hereinafter referred to as "embodiment"), asked the provinces (autonomous regions and municipalities) based on the strengthening of major backbone Water Engineering and drought emergency water source projects, large, medium, small, mini-drought-resistant water projects simultaneously, to further enhance our ability to focus and shout to the water supply and drought mitigation capabilities. To this end, the central Ministry of Finance issued 10 billion yuan of subsidies to support "embodiments." In the context of water conservation, "Water Pollution Prevention Plan of Action" for agricultural water saving irrigation will also be an important concern for the upcoming content. In addition, the Ministry of Water Resources also requires winter and spring irrigation and water conservancy construction of the total investment and strive to increase by more than 10 percent over the previous year. The total investment of 337.1 billion yuan last year, according to estimates, 2014--2015 annual water conservancy construction investment is expected to reach 370 billion yuan or more. It is foreseeable that a new round of farmland water conservancy construction boom set off. As an important part of farmland water conservancy, agricultural water-saving irrigation will also usher in a bright future. Official website: http: //www.ythlby.cn/
