The water-saving and high-yield cultivation technology for the northern winter wheat is based on the cultivation technology of adjusting the soil water at the bottom of the muddy water, reducing the number of irrigation, and increasing the yield and water use efficiency. In areas with an annual rainfall of 500 to 700 mm, this technology is used to pour 1~ during the growing period of wheat. 2 Water can reach 400-500 kilograms per mu. Technical points: 1. Planting water before planting sows and turning irrigation water into soil water. 2. Use plant type compact, high ear volume, early maturity, drought tolerance, multi-flowering and medium-grain type. 3. Appropriate late sowing, wintering seedlings of the main stem 3 to 5 leaves, both to reduce water consumption before the winter, but also provide sufficient time for the maturity of the summer corn. 4. Phosphorus fertilizers for the two crops of wheat and corn are given to wheat, and the amount of nitrogen in the base fertilizer is appropriately increased. 5. Appropriately increase the basic seedlings, reduce the spacing to 15 cm to ensure the quality of sowing. 6. In the spring, water is used for jointing to booting stage and water is poured in spring. The best combination is jointing water and flowering water. It is applicable to the northern winter wheat area and the Huang-Huai winter wheat area, and mainly includes the wheat fields in Hebei, Shanxi, Shaanxi, Shandong, Henan and other northern and central regions where water resources are relatively lacking.

The technology of high-yield and high-yielding cultivation of wheat with deep-sowing and low-strength suppression is based on the return of straw to the soil, and it breaks the bottom layer of the plough deeper, increases soil water storage, promotes the use of deep water under the roots, spins and pulverizes the stalks, and breaks the straw. Into the topsoil to improve the ability to maintain scorpion; suppression of practical plow layer to reduce the evaporation of water, cultivating strong seedlings and a whole set of cultivation techniques. Technical points: 1. Corn stalks are returned to the field and are crushed twice with straw returning machine. 2. Make 墒. Appropriate wheat plough layers with a relative moisture content of 70% to 80%, below this value should be watered to achieve 40 cubic meters per mu. 3. Deeply loose once every two to three years with a vibration deep machine and depth 30 cm. 4. Rotate the cultivator twice with a depth of 15 cm. 5. Rolling or squashing or pressing after the ploughing to break up the rubbish, practically plow the layer, and protect the drought. 6. Sowing with seeder with repressor wheel, no repressor wheel or wheat field with poor repression quality, should be repressed after sowing to ensure emergence and improve drought resistance. Applicable to the northern winter wheat area and Huanghuai winter wheat area, including Hebei, Shandong, Henan, northern Jiangsu, northern Hebei, Shanxi, Shaanxi and other places.
