黑土地保护性耕作技术推广路径与装备适应性研究OA

Black soil has abundant vegetation and long-term accumulation of organic matter,making it an important grain production base and ecological security barrier in China.However,long-term high-intensity cultivation and un-reasonable utilization have led to a decrease in organic matter content,structural degradation,and soil erosion problems.The core concept of conservation tillage technology is"less disturbance,less coverage,and more organic matter",which can effectively improve soil physical and chemical properties,enhance soil fertility,and strengthen ecological functions.This article is based on the mechanism of black soil degradation and the principle of conservation tillage technology.It analyzes the main constraints faced in the current promotion and application of this technology.To address these issues,a four in one promotion path of"policy guidance technology integration equipment support demonstration promotion"is proposed,and a regional and hierarchical technology promotion system is constructed.At the same time,based on the soil characteristics and agronomic needs of black soil areas,research is being conducted on the structural optimization and intelligent improvement direction of protective tillage equipment in areas such as no tillage sowing,straw mulching,and deep loosening land preparation,providing theoretical basis and technical support for the coordinated adaptation of protective tillage technology and equipment.
