Water-saving Agriculture Achieves "Small Construction, Great Protection"


In the past 10 years, irrigation water utilization efficiency and benefits have been greatly improved. Under the circumstances that the effective irrigated area in the country has steadily increased and the grain yield and economic crop output value have been increasing year by year, the ratio of agricultural irrigation water consumption to total water consumption has decreased from 61.4% or more. To about 55%. The effective utilization coefficient of agricultural irrigation water increased from about 0.44 in 2002 to 0.53 in 2013. Through vigorous promotion of water-saving irrigation technologies, the total net irrigation area in China has been effectively increased by 137 million mu when the total amount of irrigation water in agriculture has remained at a level of approximately 340 billion m3. At the same time, the irrigation rate of the existing irrigated area has been increased, making agriculture more comprehensive. The production capacity has steadily increased. It provided basic guarantees for the "ten-fold increase" of food production. The development of water-saving irrigation has not only improved the irrigation guarantee rate of food crops, but also enabled timely and appropriate irrigation of high-value-added economic crops, realizing the control of water demand, and the significant increase in the yield and quality of agricultural products. The change in the mode of agricultural growth has enabled the comprehensive production capacity of agriculture to increase substantially. In addition to the above achievements, water-saving irrigation technology has promoted optimal allocation of water resources and improved ecological environment. Save on irrigation water, except for new and improved irrigation areas, part of the water is transferred to industry and life, and part of the water supports ecology. The Tarim River, Heihe River and Shiyang River Basin have increased their water discharge capacity by increasing the water conservation of the middle reaches of the irrigated area, which has improved the downstream ecology. In the south, through the development of water-saving irrigation, the utilization rate of chemical fertilizers and pesticides has been increased, and non-point source pollution has been reduced; the northern well irrigation area has reduced the amount of groundwater exploitation and protected the groundwater ecological environment. The development of water-saving irrigation in pastoral areas has created conditions for rotational grazing, rest grazing and grazing bans on pastureland, and achieved small construction and major protection.
