东北黑土区玉米带保护性耕作固碳效应研究进展
Research Progress on Carbon Sequestration Effect of Conservation Tillage in Maize Belt of Black Soil Region, Northeast China
【摘要】 东北黑土区是我国重要粮食生产区,黑土地保护和利用已经上升到国家战略,目前在东北黑土区实施的保护性耕作技术是缓解气候变化的一项重要策略,但不同研究中保护性耕作对黑土固碳、释碳和作物产量的影响存在较大的差异,需要进一步阐明黑土固碳与释碳的影响机制。围绕东北黑土区玉米带的特殊环境条件以及保护性耕作方式,系统地梳理了黑土固碳与释碳理论的演变及最新试验证据,明确黑土区环境特征、施肥及耕作方式对黑土碳固存与释放的影响机制、途径及效果。提出未来黑土固碳与释碳研究的重点方向和内容,建议后续进行长期性、针对性与定量性的研究,以推动黑土固碳与释碳研究的深入开展。
【Abstract】 The northeast black soil region is an important grain producing region in China. The protection and use of black soil has become a national strategy. Conservation tillage techniques currently being used in the black soil region of the northeast are an important strategy for mitigate climate change. However, the effects of conservation tillage on black soil carbon sequestration, carbon release and crop yield were different among different studies. Therefore, the mechanism of carbon sequestration and carbon release from black soil needs further elucidation. This paper focused on the special environmental conditions and conservation tillage methods of maize belt in the black soil region of northeast China. The latest experimental evidence and the evolution of theory of carbon sequestration and release in the black soil region are systematically reviewed, and the effects of environmental characteristics, fertilization and tillage methods on carbon sequestration and release in the black soil region are discussed. We proposed the key directions and contents of future research, suggested to conduct long-term, targeted and quantitative research to promote the study of carbon sequestration and carbon release in black soil region.
