摘要: 以东北黑土区所处的特殊自然条件为背景,以黑土为研究对象,研究了长期不同施肥处理对黑土碳素及活性有机质的影响。结果表明:各施肥处理对黑土总碳、黑土有机碳和黑土活性有机质的积累均起到积极作用;有机肥与化肥配施处理较NPK处理培肥效果更佳;有机肥与化肥配施处理中,有机肥施用量对黑土总碳、黑土有机碳和黑土活性有机质的影响不明显。

Abstract: In this study, the effects of long-term different fertilizations on black soil carbon and labile organic matter were studied in a background of special natural conditions of the northeast black soil region, in order to find out the ideal proportions between organic manure and chemical fertilizer and provide reference for soil improvement in the black soil region. The results showed that each fertilizer treatment played positive role in the accumulation of total carbon, organic carbon and labile organic matter (LOM) in black soil. Compared with chemical fertilizer treatment (NPK), the treatment of combined application of organic manure and chemical fertilizer obtained the best result. In the combined application treatment, there was no obvious relationship between organic manure application amount and the contents of total carbon, organic carbon and LOM.
