From: Close correlation between sugarcane ratoon decline and rhizosphere ecological factors
Trends in the variations of enzyme activities in the sugarcane rhizosphere and theoretical yield across different ratoon ages. FST, SST, and TST correspond to rhizosphere soils from the first-year, second-year, and third-year sugarcane ratoons, respectively. Histograms depict the theoretical yield indicators of sugarcane for different ratoon ages: theoretical sugarcane yield (A) and theoretical sugar yield (B). * Significant difference between groups (P < 0.05).
