摘要: 土壤盐渍化已成为阻碍农田生态环境可持续发展的主要制约因子,且盐碱地综合治理契合保护农业生态平衡的方针政策。生物炭作为农林资源的再生产物,因其具有保水保肥、大比表面积、强吸附性等特性,在土壤改良与固碳减排等方面均具有较好的效果,实现资源化利用的同时,可以降低环境及地下水面源污染的风险,备受国内外科学领域的关注。文章综合近年来国内外对生物炭在农业领域及土壤改良方面的研究进展,总结生物炭及其复配物在农业领域及对土壤改良方面的成果,对未来生物炭及其复配物在盐碱地治理方面的应用进行探讨,且对生物炭在农业方面的应用提出不足与展望。

关键词: 生物炭;水土环境;盐碱土改良

Abstract: Soil salinization has become a major constraint to the sustainable development of the farmland ecological environment, and the comprehensive management of saline-alkali land is with a major goal of the policies for protecting agricultural ecological balance. As a regenerative product of agricultural and forestry resources, biochar has good potential for soil improvement and carbon sequestration reduction, due to its water and fertilizer retention characteristics, large specific surface area and strong adsorption. It can reduce the risk of environmental and groundwater non-point source pollution, which is of' great concern to scientists at home and abroad. The research resuhs in the field of agriculture and soil improvenmnt in recent years are summarized, and the application of bioehar and its compounds in the treatment of saline-alkali land in the future are discussed. The prospect of insuiticient application of biochar in agriculture today is put forward.

Key words: Bioehar;Water and soil environment;Saline-alkali soil improvenlent
