| 摘 要： | 为明确腐熟堆肥回用对中药渣好氧堆肥腐熟效率及堆肥产品品质的影响,探讨堆肥过程中养分转化规律及腐殖质形态、组分、品质的动态变化,在工厂化条件下比较了中药渣自然堆肥与添加腐熟中药渣堆肥(质量分数10%)堆肥过程中碳氮磷硫和腐植酸类物质的动态变化特征。结果表明,添加腐熟堆肥比自然堆肥提前20 d进入高温期,且高温期平均温度高于自然堆肥5℃左右。较之自然堆肥,添加腐熟堆肥可以强化有机物降解,堆肥产品的总碳含量与C/N显著下降(P0.05),而全氮、全磷、全钾和全硫分别增加17.5%、17.8%、14.7%和9.4%;两个处理堆肥前后总腐植酸、游离腐植酸和水溶性腐植酸含量变化不大,但添加腐熟堆肥处理可提高腐植酸的活性,增加游离腐植酸(7.8%)及水溶性腐植酸含量(30.1%);堆肥过程胡敏酸组分不断增加,富里酸组分逐渐降低,添加腐熟堆肥处理可强化堆肥腐殖化进程,增加胡敏酸组分(15.2%),胡富比显著升高,堆肥产品的分子量、缩合度及芳构化程度提高。研究表明,腐熟堆肥回流能够显著促进中药渣堆肥腐熟效率,提高堆肥产品品质。
