摘要
生物炭是指秸秆、木屑以及动物粪便等生物质在低氧或缺氧环境下通过高温热解而产生的含碳量丰富且性质稳定的有机物,由于其具有孔隙度大、密度小、比表面积大、吸附能力强、与土壤中离子交换能力强以及含碳量高等特点和优势,因此具有广泛的利用途径。生物炭对土壤理化特性的调节具有显著的影响,对土壤微生物生多样性和丰富度也有显著的促进作用,且有助于作物生长和产量的提高。因此,本文围绕生物炭施加对土壤理化特性、土壤微生物以及作物生长和产量的影响进行研究,以期丰富生物炭的利用途径,为生物炭的应用和推广提供一些思路。
Biochar is a kind of organic substance with rich carbon content and stable properties produced by the pyrolysis of biomass such as straw and sawdust under low-oxygen or hypoxic environment.Because of its large porosity,small density,large specific surface area,and adsorption features such as strong ability,strong ion exchange capacity with soil,high carbon content,etc.,have a wide range of uses.Biochar has a significant effect on the regulation of soil physical and chemical properties,it also significantly promotes soil microbial biodiversity and abundance,and contributes to crop growth and yield improvement.Therefore,this paper is based on the application of biochar to soil physical and chemical properties,soil microorganisms,and the effects of crop growth and yield,in order to enrich the use of biochar and provide some ideas for the application and promotion of biochar.
