生物炭在土壤中矿化的研究进展
Research on Mineralization Characteristics of Biochar in Soil
摘要
Abstract
Biochar mineralization can affect material cycle among the internal or external soil ecosystem, although biochar degrade slowly in soil due to its own characteristics. Researches about biochar mineralization are important for regional pattern of carbon, carbon balance and carbon storage of soil. Researchers little deduce mineralization of man-made biochar based on natural soil black carbon due to the differences among the raw materials, the reaction conditions for the Preparation of biochar and soil types. The application of stable isotope 13C technology makes the study of biochar mineralization more precise than the CO2 flow measurement and conventional subtraction method. The properties of biochar affected the characteristics of mineralization stage because of the source material, the preparation temperature, the heating rate, the final temperature and the subsequent treatment. The mineralization of biochar is caused by the combined effect of a variety of microbial communities. Microbial activity under natural conditions is affected by many environmental factors (including soil type, soil temperature, moisture and ventilation conditions, soil structure, vegetation types and farmland management mode etc.), and such factors make the rate of biochar mineralization under natural conditions is significantly less than that in laboratory.Present paper reviewed main research progress on mineralization of biochar in soil, research methods, mineralization stage, and influence factors (biochar source, producing method, producing temperature, soil type, soil temperature, soil moisture and tillage systems). In sum, we reviewed comprehensively the mineralization characteristics of biochar in soils and their microbial mechanisms.关键词
