Abstract:

To reveal the response mechanism of soil microorganisms under continuous sugar beet cropping, the authors analyzed the research progress of soil microbial community and rhizosphere micro-ecology under sugar beet continuous cropping, probed into the evolution law of soil microbial community changes, elaborated the action mechanism of soil microorganisms and rhizosphere micro-ecology under continuous cropping, and discussed the future research directions. It is pointed out that the interaction between sugar beet and microorganisms under continuous cropping is a complex process, which is affected by multiple factors and closely related to the micro-ecological environment in the rhizosphere. Under the continuous cropping condition, the micro-ecological environment of sugar beet rhizosphere changes from bacterial type to fungal type, which seriously restricts the growth, development, yield and quality of sugar beet, causing economic losses. It is suggested that in the future research, efforts should be made to study the effects of rhizosphere microorganisms and soil micro-ecology on continuous cropping of sugar beet. The obstacle mechanism of sugar beet continuous cropping should be explored by comprehensive analysis of molecular biology technology to develop new microbial agents and soil improving agents, thus providing an effective improvement scheme for sugar beet planting industry.

Key words: sugar beet, continuous cropping, microorganisms, micro-ecology, rhizosphere
