摘要 以长期定位试验为研究对象,分析了长期施肥对土壤不同层次活性碳的影响,并计算了各处理的碳库指数和碳库管理指数。结果表明,土壤活性碳均随土层的增加而减少0,~7.5 cm土层的活性有机碳平均比7.5~15 cm、15~30 cm、30~50 cm高出6.6%、23.4%、57.1%。施肥均可以提高土壤活性有机碳和碳库指数。单施有机肥培肥土壤和有机肥、化肥的配合施肥对提高土壤中活性有机碳的作用较单纯施用化肥更为显著。施肥除了绿+N、秸+N、农+绿+N处理的碳库管理指数降低外,其它各处理的碳库管理指数均有所增加。农业生产中必须重视有机肥的合理施用,使土壤碳库处于良性状态,最终才有可能维持土壤的可持续性利用。 The AC(active carbon) pool and CPMI(carbon pool management index) of soils in long-term fertilization were discussed.The results indicated that AC pool was decreased with deeper layer.The soil active carbons of soil of 0-7.5 cm soil layer were separately 6.6%,23.4%,57.1% higher than 7.5-15 cm,15-30 cm,30-50 cm.Fertilization could enhance the activity of soil organic carbon and carbon index.Single organic manure and chemical fertilizer plus manure had more significant effectiveness on increasing soil activity carbon have more significant than the chemical fertilizer.
