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
