China's climatic conditions are complex, there are many kinds of soil, and the planting system is diverse. Therefore, there are many kinds of soil preparation technology before the sowing of wheat fields, and local governments can select suitable cultivation and soil preparation technologies because of conditions. The general principle is based on ploughing (cultivation) or less no-tillage (rotary tillage) based on the combination of hoeing, hoeing, pressing, ridging, ditching, rakes, etc., to properly grasp the appropriate ploughing and hoeing. The timing of such operations will reduce the cost of farming and energy consumption, so that reasonable farming practices can be ensured. Plowing and ploughing can bury organic fertilizers, crushed crop stalks, weeds, and pest organisms, loosen plough layers, and loosen soils; reduce soil bulk density, increase porosity, improve permeability, and promote aerobic microbial activity and nutrient release; Improve soil seepage, water storage, fertilizer conservation and fertilizer supply capacity. For wheat fields that have not been ploughed before turning and cultivating wheat for many years, a solid plough bottom layer is formed below 15 cm in the rotary tillage, which affects the infiltration of the roots, the precipitation, the precipitation, and the irrigation water. It should be rotated for 3 years and the tillage for 1 year. , breaking the bottom of the plow. Less tillage and no-tillage with traditional squat ploughs have the advantages of burying straws and organic fertilizers, controlling weeds, and reducing pests and diseases. However, this traditional farming process is complicated and energy-intensive every year. Soil loss is more serious and affects wheat yield. As the effects of deep plowing can be maintained for many years, it is not necessary to plow every year. For this purpose, the soil tillage before sowing can be deep plowing for 2 to 3 years. In other years, “less no tillage†is adopted, including rotary tillage or shallow tillage. 耙耢 镇 镇 镇, 镇 镇 耙耢 耙耢 耙耢 耙耢 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 镇 耙耢 镇 镇 镇 镇 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 镇 镇 镇 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 镇 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢 耙耢In recent years, the Huang-Huai winter wheat region and the northern winter wheat region have a large area of ​​spin farming, and the surface soil of the wheat field after rotary tilling is loose. If they are not planted later, the phenomenon of deep sowing will occur and deep seeding and weak seedlings will be seriously affected. The occurrence of wheat tillers, resulting in insufficient panicles and reduced yield, can also result in the loss of soil surface layer and affect the growth of roots and wheat seedlings. Repression has the function of compacting soil, crushing soil and smoothing the ground. When the soil in the cultivating layer is too loose, the repression can make the plough layer compact, increase the soil moisture content in the plough layer, make the seeds closely contact with the soil, and promptly erupt and extend the root system. Long, down to the deep soil, the general deep soil moisture content is relatively stable, even if the upper soil is dry, the root system can absorb moisture from the deep soil, improve the drought resistance of wheat seedlings, wheat seedlings are neat and robust. Therefore, the winter wheat crop in the Huanghuai winter wheat area and the northern winter wheat area should be promptly suppressed.
