Abstract:

Soil microorganism is key components of soil ecosystem. It plays an important role in soil ecosystem sustainability and ecological service function. With the intensive comprehension of the importance of soil microorganisms in farmland and the renew of research methodology, the research work on soil microorganisms in tobacco field is highly focused. This paper expounded the current research status on soil microbe in tobacco planting soil and progress achieved in soil microbial community structure, functional microbe, microbe influencing factors and research methods. On this base, the paper put forward suggestions for future research. Emphasis must be laid on the width and depth of soil microbial research, soil microbial structure and function, utilization of soil microbial resource and molecular ecological tools. Through deepening studies on soil microbial structure and function and its application on tobacco production, theoretical and practical guidance were provided for keeping healthy soil in tobacco planting fields and upgrading the quality of tobacco leaves as well.

Key words: tobacco planting field, soil microbial community structure, nctional microbe, research methods

摘要：

土壤微生物是土壤生态系统的重要组成，对于维护土壤生态系统的可持续性及其生态功能具有重要意义。随着人们对农田土壤微生物研究重要性认识的不断提升及研究方法的更新，烟田土壤微生物的相关研究也受到高度重视。从土壤微生物的群落结构、功能微生物、微生物的影响因素及研究手段等方面，对我国烟田土壤微生物的研究现状及进展进行了综述。并在此基础上，提出了亟需在烟田土壤微生物研究的广度与深度、结构与功能、微生物的资源化应用及现代分子生物学技术应用等方面加强研究的建议。通过在烟草农业生产中深入开展土壤微生物的研究及应用，为烟田土壤健康保育及烟叶品质提升提供理论和实践指导。
