摘要
土壤有机碳能够反应土壤的质量和健康状况,其成分复杂,活性碳库对管理措施敏感,而惰性碳库则对土壤有机碳具有固存作用。为了寻找快速判断土壤质量变化的指标,前人对土壤有机碳及分级技术展开了大量的研究,其中物理分级以其破坏性小的优势而备受关注。概述了土壤有机碳的物理分级方法,探讨了在不同施肥条件下,物理分级的土壤有机碳各组分含量及分配比例的变化,并对土壤有机碳各组分所受施肥的影响及有机碳分级技术的发展趋势进行了展望。
Soil organic carbon can reflect quality and health of the soil, but it was complex in components, among which the active components were sensitive to agricultural management, while the inert components played an important role in carbon fixation. In order to find an index for determining the changes in soil quality quickly, soil organic carbon and its components were studied extensively, and physical grouping of soil organic carbon were under spotlight because of its tiny destructiveness. This paper reviewed the methods of physical grouping for soil organic carbon and explored the changes in content and allocation proportion of each component of soil organic carbon after physical grouping under different fertilization conditions.
