Abstract: Agricultural microorganism is a general term used in the fields of agricultural production,agricultural product processing,agricultural biotechnology and agricultural ecological environment protection.Agricultural microorganism play a key role in the transformation of matter and the energy cycle,and are considered to be a key engine driving the high-quality development of the agricultural industry.However,in order to realize the sustainable development of agricultural microbial industry and scientific research,from the perspective of promoting the revitalization of agricultural microbial industry,the research status of agricultural microorganisms in application fields,technology development,resource protection and strain preservation was expounded,and the problems faced by agricultural microbial research were put forward.These include intellectual property risks,low levels of scientific research and innovation, imperfect regulatory and monitoring systems,and the lack of an agricultural microbial information database.Therefore,countermeasures and suggestions were put forward to further strengthen the revitalization of agricultural microbial industry in Heilongjiang Province,namely,to carry out systematic scientific research,strengthen the construction of biosafety laboratory platform.promote the formation of industrial clusters,and strengthen policy support.
