英文摘要radix isatidis is a wide-spread medicinal herb in china. the boiled radix isatidis residue contains considerable quantities of cellulose, hemicellulose, and lignin that could be used as feedstock for biochar production. this study aims to investigate the influence of pyrolysis temperature and holding time on biochar properties as well as the effect of biochar on soil co2 emission in southern china. the biochar was prepared using pyrolysis over a temperature range of 300-700 degrees c and a holding time span of 10-180 min. the incubation experiment of soil incorporated with biochar lasted for 46 days. increasing temperature and prolonging holding time were found to reduce the volatile matter content, strengthen the carbon enrichment, and grow aromatic structure, producing alkaline biochar that has weak surface polarity, high specific surface area and extensively porous structures. the effect of biochar on soil co2 emission in southern china lays in the combined actions of biochar properties, especially of volatile matter, porous structure, and ph. increasing temperature and extending holding time may convert the positive effect into a negative effect and reduce soil co2 emission.
