“双碳”背景下我国长期肥料定位试验的研究进展

Research Progress on Long-Term Fertilizer Positioning Experiments in China Under the Background of"Carbon Peak and Carbon Neutrality"

农业具备碳源和碳汇的双重功能,是实现碳达峰、碳中和“双碳”目标的重要途径。长期肥料定位试验具有代表性、连续性、稳定性、数据丰富等特点,不仅有助于探索土壤质量演变规律,而且对于应对气候变化、实现“双碳”目标具有重要作用。通过文献分析,论述了我国长期肥料定位试验的发展、重要作用以及与实现“双碳”目标的本质关系,发现长期肥料定位试验存在重视程度和支持力度不足、试验设置落后、数据资料利用率低等问题。并在建立长期肥料定位试验研究网络、加强跨学科间的交叉、深入分析土壤固碳效应的内在机制、强化政策和经费支持等方面提出了相应建议。

Agriculture has the dual functions of carbon source and carbon sink,which is an important way to achieve the goal of carbon peak and carbon neutrality.The long-term fertilizer positioning experiments have the characteristics of representativeness,continuity,stability and rich data.It not only helps to explore the evolution law of soil quality,but also plays an important role in coping with climate change and achieving the goal of carbon peak and carbon neutrality.Through literature analysis,the development and important role of long-term fertilizer experiments in China and its essential relationship with the realization of"double carbon"goal were discussed.It was found that there were some problems in long-term fertilizer experiments,such as insufficient attention and support,backward test setting and low utilization rate of data.Suggestions were put forward in the aspects of establishing long-term fertilizer experiments research network,strengthening interdisciplinary intersection,in-depth analysis of the internal mechanism of soil carbon sequestration effect,and strengthening policy and financial support.
