微生物菌剂在盐碱土壤修复中的应用进展OA北大核心

The continuous expansion of saline soils poses a serious challenge to agricultural production and food security.As an important part of China's saline soils,coastal saline-alkali land are particularly valuable in a devel-oped coastal economy and tight arable land resource context.The higher salt content in saline soils not only de-stroys the physicochemical properties and biological characteristics of the soil but also adversely affects crop culti-vation,which in turn reduces soil fertility and crop growth potential.At present,saline soil rehabilitation generally adopts the strategy of combining various improvement technologies.The comprehensive restoration program based on microbial restoration,supplemented by microbial agents and soil conditioners,has become the most effective,widely used,and more environmentally friendly means of saline soil restoration.Therefore,this study reviewed the research on the application of microbial agents with soil conditioners,such as biochar,organic fertilizers,desulfu-rization gypsum,humic acid,algae extract,and micro/nanobubbles,which are crucial for the improvement of sa-line-alkaline land,especially coastal saline-alkaline land,and the sustainable development of agriculture.
