摘要
简述了细菌的物种多样性、适应多样性、营养代谢类型多样性和遗传多样性以及环境对其多样性的影响。细菌在农业生态系统中不仅在调节植物生长发育、抑制病原微生物方面具有积极的作用 ,而且在生态系统中的营养元素矿化、土壤肥力的保持和提高以及能量转化和物质循环等方面具有其他生物无法代替的作用。因此 ,加强对细菌功能和多样性的研究 ,有助于持续开发应用和保护微生物资源 ,充分发挥微生物在生态系统中的作用。
The diversity of species, adaptability, type of metabolism, and genetics of bacteria and effects of environments on its diversity were reviewed. As a component of agricultural ecosystem, bacteria plays unique role in regulating plant growth, inhibiting pathogenic microorganisms, mineralizing nutritive elements, increasing and maintaining soil fertility, converting energy forms and cycling materials. Therefore, research on the function and diversity of bacteria will promote sustainable development in protection and utilization of microorganism resources and agricultural production.
