摘要:

中国面临着沙地扩张及土壤沙化的严峻挑战,迫切需要进行生态修复与土壤保护。生物炭是一种由不同来源物质热解得到的富碳材料,常作为改良剂用于土壤修复,对干旱区沙质土壤改良具有重要意义。通过收集和梳理文献,总结了生物炭对沙质土壤的理化性质、固碳能力以及作物生长的影响。该综述有利于了解生物炭在沙质土壤中的应用现状,提升对生物炭改良土壤机理的认识和理解,为生物炭在沙质土壤中的实际应用和理论研究提供参考。

Abstract:

China is confronted with severe challenges of desertification, sandy land expansion, and soil degradation, which urgently necessitate ecological restoration and soil conservation efforts. Biochar is a carbon-rich material derived from the pyrolysis of various feedstocks, which is commonly used as an amendment for soil improvement and remediation, and is of significant importance for improving sandy soils in arid regions. This study examines the effects of biochar on soil physical and chemical properties, carbon sequestration capacity,and crop growth in sandy soils. This review is conducive to understanding the current status of biochar application in sandy soils and enhancing the understanding and comprehension of the mechanisms underlying biochar-mediated soil improvement. It provides a reference for both practical applications and theoretical research on the use of biochar in sandy soils.

Key words: biochar, sand restoration, soil improvement, soil carbon sequestration, soil amendment
