摘要
生物炭是一种富碳固体物质,添加到土壤后,能够封存碳,对增加碳库容量、稳定土壤碳库有着不可忽视的作用。为了进一步改良农田土壤,增加土壤碳储备,本文综述了生物炭对土壤有机碳库和无机碳库的影响。并展望了生物炭的未来研究方向和重点,提出未来的研究首先应针对特定土壤环境条件,选择适合的生物炭种类和施入量并预测施加生物炭是否会带来负面问题;其次,深入研究生物炭施用后结构性质的变化、稳定机理和对土壤中不同碳成分的影响规律;再次,建立生物炭对土壤碳库影响的数据库。一方面有利于总结归纳生物炭对土壤碳库各个组分的影响规律,另一方面可以为今后的相关研究提供更加便捷的参考途径。
Biochar is a kind of carbon-ric solid material.When it is added to the soil,it can store carbon and play an important role in increasing the carbon pool capacity and stabilizing the soil carbon pool.Inorder to further improve farmland soil,increase soil carbon storage,this paper reviewed the research on the effects of biochar on soil organic carbon pool and inorganic carbon pool.The fulure research directions and emphase of biochar were prospected,and it is suggested that the future research should first focus on specific soil environmental conditions,select appropriate biochar types and application amounts,and predict whether the application of biochar will bring negative problems;Second,in-depth study of the changes in the structure and properties of biochar after application,the mechanism of stability,and the law of influence on different soil carbon components;Third,the database of the effect of biochar on soil carbon pool was established,on the one hand,it is helpful to sum up the law of the influence of biochar on various components of soil carbon pools,on the other hand,it can provide a more convenient reference for future related research.
