紫茎泽兰制备生物炭及其应用研究进展

Advances in Preparation of Biochar from Eupatorium Adenophorum and Its Application

紫茎泽兰作为世界性的有害入侵植物,因其适应能力强、扩散速度快、植株内含有有害物质而对农林牧业乃至人类健康产生不利影响。因此,如何对其有效防控和综合利用已成为国内外关注的热点问题。生物炭是有机物质在低氧或缺氧条件下热解碳化而形成的富碳固体物质,因其独特的性质和潜在的价值而被广泛用于农业土壤改良与环境修复等领域。将紫茎泽兰热解制备生物炭,既降低了生物炭生产成本,还实现了生态系统的保护和废弃物的高效利用。目前将紫茎泽兰作为原材料制备生物炭虽有一些相关的研究,但报道相对较少,且研究较分散、结论不一。因此,有必要对紫茎泽兰的利用现状和制备生物炭的应用潜力进行综述。本文结合目前紫茎泽兰应用研究现状,分析了紫茎泽兰制备生物炭的应用研究价值,综述了其在环境污染修复、农业土壤改良方面的应用,并在此基础上提出了今后的研究方向与展望,以期为今后开展相关研究工作提供参考和借鉴。

As a worldwide harmful invasive plant,Eupatorium adenophorum has an adverse effects on agriculture,forestry,husbandry and even human health because of its strong adaptability,rapid diffusing speed and harmful substances.Therefore,how to effectively prevent,control and comprehensively utilize Eupatorium adenophorum has become a hot issue.Biochar is a carbon-rich solid material formed by pyrolysis and carbonization of organic substances under low or limited oxygen conditions.Due to its unique properties and potential value,it is widely used in agricultural soil amendment,environmental remediation and other fields.The pyrolysis of Eupatorium adenophorum to produce biochar not only reduces the production cost of biochar,but also protects the ecosystem and re-uses the waste efficiently.At present,although there are some studies on the preparation of biochar from Eupatorium adenophorum,the reports are relatively few,and the researches are scattered and conclusions are different from one to others.Therefore,it is necessary to review the current utilization status of Eupatorium adenophorum and the application potential of biochar.Based on the current research status of Eupatorium adenophorum in application,this paper analyzes the research value of the preparation of biochar from Eupatorium adenophorum and summarizes its application in environmental remediation and agricultural soil amendment,then puts forward the future research direction and prospect,with a aim to provide a reference for the coming researches.
