生物炭施用对农业生产与环境效应影响研究进展分析

Progress in Research on Biochar Affecting Soil-water Environment and Carbon Sequestration-mitigating Emissions in Agricultural Fields

生物炭(Biochar)因其特殊性质而被广泛应用在土壤改良和固碳减排等方面,因潜力很大,备受国内外学者的关注。然而,生物炭性质不仅因生物质制备材料来源不同而有所差异,还受到热解温度和工艺的影响。同时,生物炭性质和土壤条件差异也在较大程度上影响其改良土壤效果和固碳减排成效。综述近年来国内外有关生物炭在农田水土环境及固碳减排影响的研究进展,总结了生物炭在农业领域、固碳减排及盐碱地改良等方面的研究成果,分析了现存问题,并对生物炭在农业相关领域的研究应用进行了探讨,旨在为广泛应用生物炭技术提供借鉴和参考。

Biochar has been widely used in soil improvement and carbon sequestration. It has great potential and has attracted much attention in the scientific field at home and abroad. However, the properties of biochar are not only affected by the sources of biomass materials, but also related to pyrolysis temperature and technology. At the same time, different biochar properties and soil conditions also greatly affect the effect of soil improvement and carbon sequestration. In this paper, progress in research on the biochar affecting soil and water environment and carbon sequestration in farmland is reviewed. The study summarize the research achievements of biochar in agriculture, carbon sequestration and reduction, and improvement of saline and alkaline land, analyze the existing problems and discuss the application of biochar in these fields in the future. The purpose of application of biochar. this study is to provide references for the wide
