A few days ago, the General Office of the Ministry of Water Resources announced the list of water-saving irrigation areas in 2022, and the flood river irrigation area of Minle County was awarded the national water-saving irrigation area. According to the notice issued by the General Office of the Ministry of Water Resources, in order to implement the National Water-saving Action Plan and do a good job in the construction of water-saving irrigation areas, the construction materials of water-saving irrigation areas reported by various places as of the end of October 2022 were reviewed, and on-site inspections were conducted in some irrigation areas. According to the results of the review, there are 182 irrigation areas in the country with standardized agricultural water management, with obvious water-saving benefits, and have good promotion significance in the construction of water-saving irrigation areas.
Relying on project construction, make up for the shortcomings of water resources utilization. In recent years, the Honghe Management Office has comprehensively carried out the creation of water-saving irrigation areas, deepened the comprehensive reform of agricultural water prices, standardized agricultural water use in irrigation areas, and played a role in demonstration and promotion, in order to ensure national food security, Honghe Irrigation Area, as a key grain production base in Hexi region of Gansu, explored and summarized some good practices and experiences in agricultural water-saving irrigation. The designed irrigation area of the irrigation area is 427,100 mu, and the effective irrigation area is 402,000 mu. In the 70s of last century, the irrigation area built one medium-sized reservoir of Shuangshusi with a storage capacity of 25.8 million m3, and in recent years, three small reservoirs were completed and put into operation in Shanchenghe, Jinshan No. 1 and Jinshan No. 2, with a total reservoir capacity of 9.26 million m3. In 2022, the interconnection of the county canal system water network connection project to bring benefits into the sea and into the children's project will realize the adjustment of water surplus shortage between irrigation areas, create favorable conditions for the unified dispatch of water resources in the county, and lay the foundation for ensuring flood control, water supply, food security and ecological security in the county.
Implement water-saving actions to improve the efficient and economical use of water resources. In accordance with the requirements of the construction of water-saving irrigation areas, fully implement the national water-saving action, rely on project construction and take water-saving project construction as the starting point, further improve and improve the water management system in irrigation areas, continue to carry out the construction of supporting facilities and water-saving engineering projects in irrigation areas, through water-saving supporting transformation, safe and stable project operation, achieve "smart water conservancy" through standardized operation, rely on agricultural water price reform to promote the creation of water-saving types, actively explore water resources and water ecological civilization construction models and experiences, and the integrity rate of backbone water transmission projects reaches 92.5% The anti-seepage rate of channels in irrigation areas has been significantly improved, reducing the loss of water transmission in the channel and the phenomenon of dripping and leakage of the gate. The comprehensive benefits of water saving in irrigation area projects are remarkable, and the utilization rate of canal water has increased from 0.53 to 0.65 now; the utilization rate of irrigation water has increased from 0.49 before reconstruction to 0.57 after reconstruction. Through the construction of water-saving irrigation areas, the efficiency of agricultural water use in irrigation areas has been greatly improved, playing an irreplaceable role in ensuring food security and rural revitalization.
Strengthen water-saving measures and consolidate the foundation for the construction of a water-saving society. According to the growth cycle of wheat and other crops and the optimal irrigation time node, the management office instructs the people in the irrigation area to use water in a timely and appropriate amount according to the round, implement efficient water saving, vigorously promote conventional water-saving measures such as large-scale renovation, furrow irrigation, wheat grass mulching, etc., put an end to the flood irrigation mode, during the peak period of summer irrigation water, overall planning, scientific scheduling, increase the flow of channel water, ensure timely irrigation of crops, the irrigation water cycle has been shortened from the original 35 days to 30 days, and the average mu water use has been reduced from 420m3 to 380m3 since the "Thirteenth Five-Year Plan" , effectively saving water resources. At the same time, relying on the successful water-saving irrigation model and water-fertilizer integration engineering system in the irrigation area, we actively promote the construction of a water-saving society and comprehensively improve the efficiency of water resource utilization, and the water-saving effect of agricultural irrigation has been outstanding in recent years.
Strengthen publicity and guidance, and form a good atmosphere for joint efforts and joint construction. Actively carry out publicity on the construction of a water-saving society, create an atmosphere for creating a good water-saving irrigation area, improve the public's awareness of water conservation and water conservation, combine the publicity activities of "World Water Day and China Water Week", carry out mass water-saving publicity activities such as "building happiness canals and promoting water culture festivals", implement activities such as water-saving publicity into communities, schools, villages and households, and make full use of public media such as banner slogans, display boards, Longzheng nails, QQ groups, WeChat moments and other public media to implement national water-saving actions and popularize water-saving knowledge. Publicize water-saving related policies, and create a good atmosphere where water conservation starts from me, and everyone participates in the construction of a water-saving society.
