Analysis of rhizosphere microbial ecological factors in sugarcane ratoons of different ages-ITS Raw sequence reads

Examining the trends, interrelationships, and interactive effects of rhizosphere physicochemical factors, biochemical functional factors, enzyme activities, microbial diversity, and endophytic bacterial diversity in different years of sugarcane ratoon growth can provide valuable insights into the mechanisms underlying sugarcane ratoon decline. Currently, systematic investigations in this area are lacking. The present study focuses on the ecological factors of the rhizosphere of different sugarcane ratoon plots (same variety) planted under the same climatic and soil conditions. By analysing the dynamic variations and correlations among rhizosphere ecological factors at different temporal scales (different ratoon ages) and their associations with the properties of sugarcane growth, we aimed to investigate the relationship between sugarcane ratoon decline and rhizosphere ecological factors. The results of this study may improve the growth and yield of sugarcane ratoons.
