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.

Key words: biochar, saline-alkali soil, physicochemical properties, nutrients, microorganisms
