Carbon Sequestration Study of Sugarcane based on Biomass Observation Experiments
摘要
Abstract
To further investigate changes in sugarcane carbon sequestration capacity through biomass observation techniques,this study analyzes the carbon sequestration capacity of sugarcane and its influencing factors based on biomass observation data from field experiment sites and large-scale experimental fields in Guangxi's main sugarcane-growing areas from 2022 to 2024.The results showed that the carbon fixation of sugarcane aboveground parts increased monthly from May to October and slightly decreases in November,with the lowest value of 0.007 t/hm2 in May and the peak value of 0.065 t/hm2 in October.Significant differences in carbon fixation were observed across different years,planting seasons,and regions.Ratoon sugarcane had higher carbon fixation than newly planted sugarcane during the early growth stage,while newly planted sugarcane showed stronger carbon sequestration capacity during the maturity stage.The carbon fixation was higher in low-latitude regions,indicating that climatic conditions play an important role in carbon sequestration.The findings provide a scientific basis for optimizing sugarcane planting management and enhancing carbon sequestration capacity.关键词
