In 2022, Minqin County adheres to the water-saving idea of "water-saving priority, spatial balance, systematic governance, and two-handed force", focuses on industrial water-saving and life water-saving, based on the development positioning of ecological function and agricultural priority, actively adjusts the agricultural planting structure, implements the strictest water resources management system, vigorously promotes efficient agricultural water-saving technology, and accelerates the promotion of deep water-saving in agriculture. The county's efficient water-saving irrigation area reached 580,000 mu, and the utilization rate of irrigation water reached more than 63%.

Rural revitalization focuses on industrial revitalization, how to let the field give full play to the greatest advantages, improve land utilization, but also can save water resources, Minqin County Suwu Town Yuantai Village found a breakthrough. This year, Yuantai Village took the "express train" of corn and soybean strip compound planting, transferred land, and signed a land trusteeship agreement with Yuantai Village for the people's agricultural and animal husbandry and agricultural machinery professional cooperative, to carry out refined management of farmland, so that the land can be revitalized, so that everyone can do something, can increase income, and continuously enhance the collective economic strength.
Walking into the soybean corn strip compound planting area in Yuantai Village, Suwu Town, looking around, the corn is growing happily, and the soybeans are lush at the feet of the corn, and the green leaves can be seen that the inside is full of soybean pods, and each soybean is full and round.
"All cultivated land implements efficient water-saving drip irrigation projects, all of which adopt sub-membrane drip irrigation technology, from flood irrigation to precision control, crops eat 'planned' water, effectively reducing water waste." Ma Shangfu, secretary of the party branch of Yuantai Village, calculated that this year's water cost alone can save more than 30,000 yuan.

The water-saving account is linked to the revenue account. "Corn does not reduce production, harvest an extra crop of beans." The "corn + soybean" set of planting mode avoids the crop side effect, solves the traditional single planting mode of low production efficiency, economic efficiency is not high prominent problems, improves the light space of soybeans, through soybean nitrogen fixation, compatible with corn development, improve soil fertility, save water and land, to achieve the purpose of stabilizing corn yield and increasing soybean production capacity.
Ma Shangfu introduced that the yield of soybeans per mu is more than 300 jin, and compared with the single crop of corn, the income per mu is at least 1,000 yuan, which can achieve "double harvest in one season".
In early autumn, 1,000 acres of efficient water-saving irrigation demonstration sites in Xing'an Village, Changning Town, Minqin County, crisscrossed 4,800 acres of corn fields. The verdant corn is growing happily and the harvest is imminent.
This spring, in accordance with the idea of "turning small pieces into large blocks", Xing'an Village carried out centralized exchange of cultivated land, the whole village implemented the transformation project of field irrigation and water-saving facilities, and all cultivated land in the village installed high-efficiency water-saving facilities.
Villager Wang Jianmin planted 50 acres of corn, and he has a deep understanding of the benefits of water conservation, and in the past, the use of large water flood irrigation had low efficiency, large water consumption, and high planting costs. "This year, we use the sub-membrane drip irrigation water and fertilizer integration method, watering is particularly convenient, one acre of land can save 130 square meters of water, the poured out of the ground is soft, not compact, is conducive to the absorption of water and fertilizer nutrients by the root system of crops."

Through the vigorous development of high-efficiency water-saving irrigation projects and the promotion of water-fertilizer integrated water-saving agricultural technology, Minqin County has greatly improved the utilization rate of water resources while also improving agricultural economic benefits, making water-saving irrigation a "standard" for more and more farmland. "Compared with field flood irrigation, the water saving per mu is more than 30%, and the water saving effect is very obvious." Ma Xinhua, director of the water conservancy station in Changning Irrigation District, Minqin County, said that the integration of water and fertilizer has reduced fertilizer losses, saving fertilizer by up to 30-40%, and reducing fertilizer costs by 120 yuan per mu.
At present, the agricultural water-saving facilities in Minqin County have been promoted on a large scale, bringing the masses the "source of living water" for rural revitalization.

After using the micro-sprinkler irrigation facility for the thousands of acres of alfalfa in Caiqi Village, Caiqi Town, Minqin County, the watering of alfalfa has been transformed from flood irrigation to fine sprinkler irrigation, and the good effect of saving water by about 100 square meters compared with conventional irrigation methods has been obtained. Not only that, saving labor, saving time, saving effort, and low cost, these advantages made bai Jianhe, the person in charge of the base, have no worries about experimental planting at the beginning. "After the use of sprinkler irrigation technology, sowing, irrigation, fertilization, etc. have been mechanized, which has greatly saved planting and labor costs."
The water is stable and the industry is booming. Minqin County strictly implements the requirements of "deep water saving and extreme water saving", adheres to the water adjustment structure, water to determine the industry, and determine the scale with water, accelerates the pace of industrial restructuring, bases itself on high-standard farmland, fully explores the potential of farmland to save water, enhances farmers' awareness of water conservation, ensures that limited water resources can exert maximum benefits, and helps agricultural water-saving transformation and upgrading.

"Agriculture, as a pillar industry of civil service, must take the road of efficient water-saving irrigation to break through water constraints." Zhao Xingyan, deputy director of the Minqin County Water Affairs Bureau, said that by creating high-efficiency water-saving demonstration points, comprehensively promoting water-saving technologies such as drip irrigation under the film, integration of water and fertilizer, and ridge-membrane ditch irrigation, etc., to achieve full coverage of efficient water-saving irrigation, to achieve agricultural water-saving and increased production, and farmers to save costs and increase efficiency.
In 2022, Minqin County will build 43 agricultural high-efficiency water-saving demonstration sites with a demonstration area of 66,500 mu. Through the demonstration and promotion of international and domestic advanced water-saving irrigation technologies such as drip irrigation, sprinkler irrigation, ridge film ditch irrigation, automation, and precision irrigation, we will create demonstration sites for deep water-saving and extreme water-saving in the agricultural industry, and implement rotational fallowing of about 130,000 mu; Completed the renovation of 1368 sets of groundwater metering facilities, it is expected to reduce the amount of groundwater extraction by more than 100 million cubic meters throughout the year, so that the "large water flood irrigation" method becomes "precision drip irrigation", realizing farmers' cost savings, increasing efficiency, increasing income and saving expenditure, and providing a strong "water support" for rural revitalization.
