| 摘 要： | 近年来开展了大量短期一次性施用生物质炭对作物产量、土壤碳库和温室气体排放的研究。研究表明生物质炭能增加土壤碳库,但对作物产量、CH4和N2O排放的影响受生物质炭性质和土壤类型影响。生物质炭用在酸性土壤上比中性或碱性土壤上更能提高作物产量。草本或木本炭能减少N2O排放,但畜禽粪便炭不能减少N2O排放。在热带、亚热带地区生物质炭施用对N2O的减排作用小于温带地区。生物质炭的固碳减排效应除了受生物质炭类型、稳定性和施用区域影响外,还受制炭能耗和裂解气回收技术影响。在未来发展方向上,提出了亟需加强制炭技术、长期连续施用生物质炭效应和生物质炭性质与土壤类型互作研究。

| Abstract: | In last decade, a lot of work has been done on the effects of short-term and one application of biochar on crop yield, soil carbon sequestration and greenhouse gases emissions. Results show that biochar can increase soil organic carbon. However, the effects of biochar on crop yield, CH4 and N2O emissions vary with biochar types and soil properties. Increase magnitude of biochar application in acid soil is higher than that in neutral or alkaline soil. Straw or wood biochar can decrease farmland N2O emission, however manure biochar can''t. The decrease magnitude of biochar application on N2O emission in tropical and subtropical area is smaller than that in temperate area. In addition, the effects of biochar on greenhouse gas mitigation are also impacted by biochar production technique. Before biochar can be extensively used, the effects of long-term and multi-application of biochar on crop growth and soil greenhouse gases emissions, and interactions of biochar properties and soil types must be investigated. And the biochar production techniques must be explored. |
