不同蔗叶处理对红壤团聚体中有机碳和微生物的影响
Effects of different sugarcane leaf treatments on microorganisms and organic carbon in red soil
摘要
Abstract
To investigate the effects of different sugarcane leaf-derived materials on typical red soil in sugarcane-growing regions of Yunnan,a soil incubation experiment was conducted with a control group(CK)and three treatments,including shredded sugarcane leaves(ZY),sugarcane leaf biochar(SWT),sugarcane leaf ash(FS).This study analyzed changes in bacterial and fungal community structures and diversity,as well as in the proportion of water-stable macroaggregates and the organic carbon content within soil aggregates.The results showed that,compared to the CK,all treatments resulted in a decrease in the proportion of aggregates in the[0.25,0.5]mm and(0.5,1]mm size ranges,while no significant differences were observed for other aggregate size classes.Additionally,a decrease was observed in the organic carbon content in the[0.25,0.5]mm aggregates.The ZY treatment exhibited changes in both bacterial and fungal community structures.The SWT treatment increased bacterial species richness and diversity but did not affect the fungal community structure.The effects of the FS treatment were similar to those of the SWT treatment.These findings indicate that under conditions of relatively low organic matter and nitrogen availability,treatments with ZY,SWT,and FS were not conducive to the formation of soil aggregates or the accumulation of organic carbon within aggregates.关键词
