The invention discloses a soil improvement method under a crop rotation system of wheat-corn in a tide soil region of North China. The method aims at solving the technical problems of shallow soil tillage layer and low soil water and fertilizer conservation capacity. The method comprises the following steps: in a wheat planting season, corn stalks of the last season are crushed and the whole amount of straws is returned to the field combined with soil rotating tillage. The depth of the rotating tillage is controlled to 15-18 centimeters, and basal fertilizer especially for the wheat is appliedwhile the wheat is sowed. Urea is applied to wheat during green-back period, and watering is carried out in time after the application. In a corn planting season, the wheat stalks of the last seasonare crushed and returned to the field in full amount in combination with the deep loosening of soil spacing. The distances between deep loosening ditches are determined according to the distances between the sowing rows of the corn. Fertilizer especially for the corn is applied while the corn is sowed. The corn is sowed between two adjacent deep lessening ditches or tillage-free areas in the ditches. The method can improve the structure of soil arable layers, promote the expansion of the arable layers, improve the production performance of the soil, ensure the uniform distribution of nutrientsbetween arable layers, promote the growth of crops, and improve the unit yield.
