Clarify the development direction of efficient water-saving agriculture, ecological agriculture and circular agriculture, formulate water-saving agriculture development plan, adjust and optimize agricultural planting structure, promote advanced water-saving irrigation technology, and reduce farmland irrigation quota… Minqin County, Wuwei City, Gansu Province, vigorously develops “dry farming+water-saving agriculture”, and walks out a new way to restore natural ecology and develop modern agriculture in northern desert oasis areas.
In recent days, in the potato breeding base of Malianjing Village, Nanhu Town, Minqin County, the contiguous potato branches and leaves are particularly luxuriant. Yang Rui, the chairman of the National People’s Congress of Nanhu Town, carefully digs the soil with a hoe, and round potato grains knot on the thick roots of potatoes, bringing drops of water from drip irrigation.
Water droplets contain soluble solid or liquid fertilizers required for the growth of seed potatoes. “Yang Rui said that potatoes are drought resistant, barren, and water-saving crops with strong adaptability to soil. During the planting process, Nanhu Town introduced high-tech agricultural machinery and used high-tech technologies such as Beidou positioning, automatic control, and inertial navigation to control water, fertilizer, medicine, and film in the production process of ridge soil, film covering, fertilization, sowing, and irrigation, Greatly reducing agricultural production costs and significantly improving potato quality and yield.
In the belt compound planting area of soybean and corn in Yuantai Village, Suwu Town, Minqin County, corn and soybean belong to monocotyledonous Poaceae and dicotyledonous leguminosae.
“The base applies the belt composite planting technology of corn and soybean, changing the single set of single row spacing planting to the wide narrow row double set double belt planting, and changing the sparse planting to the dense planting, so as to achieve the goal of double harvests of corn and soybean.” Ma Shangfu, secretary of the Party branch of Yuantai Village, said that Suwu Town implemented the efficient water-saving irrigation project for the composite planting area, and adopted the water-saving technology of “integration of water and fertilizer under film drip irrigation” to precisely control and plan water use, Transforming “watering the land” into “watering crops” allows limited water in the soil to circulate between the soil and the plastic film, reducing inter plant evaporation of crops, and achieving water-saving, yield increasing, and efficiency enhancing.
Minqin County, located in the northeast of Hexi Corridor in Gansu Province, is located in the lower reaches of Shiyang River Basin, and is surrounded by Tengri and Badain Jaran deserts in the east, west and north. It is a resource type area with serious water shortage, fragile ecological environment, low precipitation and large evaporation, which once restricted the development of local agriculture.
In recent years, the county has solved the water shortage dilemma by “deep water-saving and extreme water-saving”. Following the technical path of “using water to promote fertilizer, using fertilizer to promote water, coupling water and fertilizer, and efficient utilization”, the county has comprehensively promoted “dry farming+water-saving agriculture”, adopted a dual mode design of “pipe irrigation+drip irrigation”, prioritized the selection of high standard farmland with centralized connection and good site conditions, and constructed integrated water and fertilizer facilities to create excellent water, fertilizer, air, and The thermal environment maximizes the utilization rate of water and fertilizer, realizing the transformation from Extensive farming to precision agriculture, and from traditional agriculture to modern agriculture.
