| 摘 要： | 盐碱土壤是中国重要的一种中低产土壤类型,由于土壤退化,盐碱地成了重要的后备耕地资源。生物炭作为农业的土壤改良剂、碳封存体和肥料的缓释载体越来越被广泛地认识和关注,在促进农业可持续发展中前景重大。通过综合分析生物炭的施加对盐碱土壤的物理化学性质、养分含量变化、微生物方面及作物生物量的研究进展,分析生物炭在盐碱地的改良效果,总结了生物炭在盐碱地改良的可能机制,以期为盐碱地的治理提供参考。

| Abstract: | Saline-alkali soil is an important type of low and medium yielding soil in China, and due to soil degradation, saline-alkali land has become an important reserve arable land resource. Biochar has been more and more widely recognized as a soil conditioner, carbon sequester and slow-release carrier of fertilizers in agriculture, and has great application prospects in promoting the sustainable development of agriculture. By comprehensively analyzing the research progress of biochar application on physicochemical properties, content change of nutrients, soil microorganisms and crop biomass of saline-alkali soil, we studied the improvement effects of biochar on saline-alkali soil and summarized its possible mechanism of soil improving, with a view to providing support for saline-alkali land management. |
