Abstract Application of biochar-based fertilizer (BF), produced by combining biochar with chemical fertilizer, is known to be an effective way to increase plant growth and soil organic carbon (SOC) stock, but its impact on soil respiration (RS) components and associated mechanisms in subtropical plantations remain unclear. The objectives of this 12-month field study were (1) to examine the effects of the application of a BF versus a chemical fertilizer (CF) on seasonal variations in soil heterotrophic (RH) and autotrophic (RA) respiration in a subtropical plantation of Moso bamboo (Phyllostachys edulis), and (2) to investigate relationships between soil RH and RA and soil environmental factors in different fertilizer treatments. Four treatments were tested: control (no fertilizer applied), BF application, CF application, and a 50: 50 mixture of BF and CF (BCF). Irrespective of the treatment, both RS and RH exhibited strong seasonal patterns. However, adding CF in the soil significantly increased the soil RH whereas BF decreased it (P

对比亚热带毛竹种植园土壤异养和自养呼吸对生物炭和化肥的短期响应

摘要 生物炭与化肥结合生产的生物炭基肥料（BF）的施用被认为是增加植物生长和土壤有机碳（SOC）储量的有效方法，但其对土壤呼吸（RS）组分和亚热带种植园的相关机制尚不清楚。这项为期 12 个月的实地研究的目的是 (1) 检验 BF 与化肥 (CF) 的施用对亚热带种植园中土壤异养 (RH) 和自养 (RA) 呼吸的季节性变化的影响毛竹 (Phyllostachys edulis) 和 (2) 研究不同肥料处理中土壤 RH 和 RA 与土壤环境因素之间的关系。测试了四种处理：对照（​​不施肥）、BF 施用、CF 施用和 50：50 BF 和 CF (BCF) 的混合物。不管治疗如何，RS 和 RH 都表现出强烈的季节性模式。然而，在土壤中添加 CF 显着增加了土壤 RH，而 BF 降低了它（P
