April 27，The Land Construction Research Institute invites Northwest A&F University to become an associate professor，I gave an academic report entitled "Agricultural Microbial Technology and Environmental Ecological Restoration" in the Chanba Soil Organic Reconstruction Core Experimental Area,All employees of the institute participated。

In his report, Associate Professor Laihanghang first used the concept of circular economy to develop ecological agriculture and the resource and environmental constraints in agricultural production as the starting point，Systematically discusses the harmlessness and resource utilization treatment technology and process flow of organic waste，Detailed introduction to the manifestations of soil biological degradation and the technical route for soil microbial remediation、Research Progress、Industrial promotion and application effects and examples, etc.。Associate Professor Laihanghang also listed a large number of domestic and foreign engineering cases，In combination with the research work of individuals and research groups，Focus on the actinomycete resources in high-salt environments in the northwest region、Separation method、Actinomycete diversity and identification of new species、Research results on the salt tolerance mechanism of halophilic dafabet mobile loginbacteria and genetic screening of antagonistic strains。

Research on biological reconstruction of soil is one of the important research fields in the discipline of land engineering，It is also an important part of the theory of organic reconstruction of soil。Expanding professional knowledge of microorganisms in soil functional restoration is beneficial to improving the skill level of land engineering practitioners in the field of soil organic reconstruction。

After the meeting，Associate professor Laihanghang also had an in-depth discussion with the researchers of the institute on the problems existing in the process of integrating scientific research and engineering，Provided valuable suggestions for ongoing research and upcoming work。
