The invention provides a method for improving soil productivity in a wheat-corn rotation area of the old Yellow River, and relates to the technical field of crop cultivation. The invention adopts the method of combining straw returning and tillage, no tillage in the corn season, rotary tillage in one year in the wheat season, and ploughing in the next year, alternately, so as to continuously improve the basic soil fertility level of the middle and low-yield fields in the old Yellow River and improve the resource utilization efficiency. It is of great theoretical and practical significance for the improvement of the comprehensive grain production capacity of medium and low-yield fields. It is not only conducive to the increase of wheat and corn production, but also maintains and promotes the slow improvement of soil quality. sustainable farming models. |
