施用稻壳炭对三七连作土壤活性有机碳组分的影响
Effects of Rice Husk Biochar Application on Labile Organic Carbon Fractions in Continuous Cropping Soil of Panax notoginseng
摘要
Abstract
Through indoor cultivation experiments,the effects of different application rates of rice husk char-coal on the active organic carbon components in soil under continuous Panax notoginseng cultivation were in-vestigated.Results indicated that applying rice husk charcoal significantly increased soil organic carbon and the content of various active components,with the enhancement effect increasing with higher application rates.Af-ter 30 days of cultivation,compared with the control,the T2 treatment increased oxidizable organic carbon,mi-crobial carbon,dissolved organic carbon,and total organic carbon content by 7.94-fold,31.52％,56.40％,and 59.56％,respectively.The T1 treatment also significantly increased the content of each component,but the in-crease was lower than that of the T 2 treatment.The results indicate that appropriate addition of rice husk charcoal can effectively increase the content of active organic carbon in soil under continuous ginseng cultiva-tion,providing scientific basis for alleviating continuous cropping obstacles and restoring soil ecosystems by improving soil carbon cycling.关键词
