Over the past five years, the country’s new efficient water-saving irrigation area of 100 million mu, more efficient water-saving irrigation area of more than 300 million mu. China’s agricultural farewell traditional flood irrigation, from the “pouring” to “pouring crops”, agricultural production mode due to water and change, the effective utilization of irrigation water to reach 0.542, while safeguarding national food security, agricultural irrigation water to achieve zero growth.
These years, all over the country to grasp the water and water. The northwest region to promote water-saving grain, the development of efficient water-saving irrigation; the Northwest region rational control of irrigation scale, vigorously promote drip irrigation, sprinkler and other efficient water-saving technology; North China pressure groundwater, the development of low-pressure pipe irrigation, irrigation and water and fertilizer integration; To channel seepage-based, economic crop cultivation areas to promote high-efficiency water-saving irrigation technology, improve fertilizer, pesticide use efficiency. Dredge the field of “capillaries”, small rural water key county construction reached 2450 counties, basically covering the main agricultural and animal husbandry counties, and to the easy hills and hills, concentrated contiguous poverty area tilt. The full implementation of irrigation field field terminal facilities, “five small water” project, hilly area rainwater irrigation, river pond dredging and other construction projects, the initial formation of large and small micro-simultaneously farmland water conservancy engineering system, open up farmland irrigation “Finally one kilometer”.
Through the development of efficient water-saving irrigation, the project area mu yield 10% to 40% of grain, a substantial increase in grain production capacity. Compared with the traditional irrigation, efficient water-saving irrigation acres can reduce the use of 3 to 5 working days, improve fertilizer, pesticide utilization rate of 5% to 20%. It is reported that by 2020 will be basically completed 434 large-scale irrigation and 2157 key medium-sized irrigation water-saving transformation. By then, the country’s efficient water-saving irrigation area accounted for the proportion of effective irrigation area will be increased to more than 30%, farmland irrigation water effective utilization coefficient of 0.55 or more.
