Unmanned Conservation Tillage Model for Hilly Slope Land of Black Soil

Without altering the original structure of cultivated land, it maximizes resource conservation, realizes efficient resource utilization, and improves agricultural production efficiency. In view of the fact that current tillage practices fail to meet the protection requirements of black soil, the third-generation intelligent agricultural machinery and supporting implements are developed under the special research program for black soil.

Demonstration applications targeting hilly slope lands are carried out at Dahewan Farm. Relying on diversified complete sets of intelligent agricultural equipment and unmanned operation solutions, combined with conservation tillage technologies such as "subsoiling plus straw returning to the field" and "subsoiling plus straw returning to the field plus contour planting", this study measures indicators including plant height, leaf area, dry matter accumulation, soil water content, rainfall, surface runoff, sediment yield and 100-kernel weight of crops (maize and soybean) under different conservation tillage treatments.
