| 摘 要： | 采用玉米秸秆、玉米秸秆生物质炭及其两者配合施用于红壤旱地的田间试验,通过有机碳分组、微孔板荧光法及底物诱导呼吸手段,研究不施肥条件下土壤有机碳组分、土壤酶活性及微生物底物利用速率的变化。结果表明:施用9个月后,与对照(不施任何物料)相比,单施秸秆提高土壤易矿化碳含量,对pH、总有机碳含量、惰性碳含量影响较小,而生物质炭及其与秸秆配施显著提高土壤总有机碳和惰性有机碳含量。单施秸秆提高土壤β-葡萄糖苷酶活性,而生物质炭及其与秸秆配施对土壤酶活性无影响。单施秸秆提高土壤微生物对葡萄糖、天冬氨酸和丁香酸的利用速率,提高土壤基础呼吸速率,而生物质炭及其与秸秆配施对土壤呼吸和微生物底物利用速率无影响。生物质炭与秸秆配施对土壤易矿化碳组分和基础呼吸呈显著互作效应。土壤基础呼吸与易矿化碳含量、β-葡萄糖苷酶活性及葡萄糖利用速率呈显著正相关。因此,秸秆炭化相比秸秆直接施用更有利于提高土壤稳定性碳库,降低土壤碳排放。
