菌糠与有机肥对设施土壤有机碳库和团聚体稳定性的影响
Effects of spent mushroom substrate and organic fertilizer on soil organic carbon storage and aggregate stability in facility soil
为探究菌糠与有机肥配施对设施土壤有机碳库和团聚体稳定性的影响,以设施辣椒土壤为研究对象,设置空白对照(CK)、单施菌糠(JK)、低量菌糠与有机肥配施(LKF)、中量菌糠与有机肥配施(MKF)和高量菌糠与有机肥配施(HKF)等5个处理。研究结果表明,MKF处理在0~<15 cm和15~30 cm的两个土层下的土壤有机碳(SOC)含量较CK高出25.7%和52.3%,而可溶性有机碳(DOC)分别高出38.7%和39.6%。JK、LKF和HKF处理在0~<15 cm土层的固碳潜力分别达到0.38、2.05、2.78和3.05 t·hm-2,在15~30 cm土层下JK、LKF、MKF和HKF处理的固碳潜力依次为0.22、1.67、4.30和2.23 t·hm-2。4个菌糠与有机肥配施处理均显著提高了土壤平均重量直径(DMW)和几何平均直径(DGM)。相关性分析表明,有机碳与有机碳储量、固碳潜力之间呈现极显著的正相关关系。综上,中量菌糠与有机肥配施(MKF)可显著提升设施土壤有机碳储量、固碳潜力及团聚体稳定性,为黄土高原设施土壤地力培育提供有效的最优策略。
To investigate the effects of spent mushroom substrate and organic fertilizer on the soil organic carbon storage and aggregate stability in greenhouse soil. Five treatments were established: Control (CK), single application of spent mushroom substrate (JK), low rate of spent mushroom substrate and organic fertilizer (LKF), medium rate of spent mushroom substrate and organic fertilizer (MKF), and high rate of spent mushroom substrate and organic fertilizer (HKF). Results showed that the content of soil organic carbon (SOC) in MKF treatment was 25.7% and 52.3% higher in the 0~<15 cm and 15~30 cm soil layers. Compared with CK and the content of dissolved organic carbon (DOC) increased by 38.7% and 39.6%, respectively. The carbon sequestration potential of the JK, LKF, and HKF treatments in the 0~<15 cm soil layer were 0.38, 2.05, 2.78, and 3.05 t·hm-2, respectively. The carbon sequestration potentials of the JK, LKF, MKF, and HKF treatments in the 15~30 cm soil layer were 0.22, 1.67, 4.30, and 2.23 t·hm-2, respectively. Four combining spent mushroom substrate and organic fertilizer significantly increased the mean weight diameter (DMW) and geometric mean diameter (DGM) of soil aggregates. Correlation analysis indicated that organic carbon showed a highly significant positive correlation with organic carbon storage and carbon sequestration potential. In summary, the combined application of medium grade spent mushroom substrate and organic fertilizer (MKF) can significantly enhance the organic carbon storage, carbon sequestration potential, and aggregate stability of greenhouse soils, providing an effective and optimal strategy for improving soil fertility in greenhouse soils on the Loess Plateau.
