摘　　要： 测定八角下脚料与甘蔗滤泥、桐麸联合堆肥过程中温度、C/N比、种子发芽指数(GI)等腐熟度指标,研究各项指标在堆肥进程中的变化情况。结果表明:GI可作为八角下脚料与甘蔗滤泥、桐麸联合堆肥评价堆肥腐熟度的主要评价指标。在起始C/N比为31.45条件下进行八角提油下脚料、甘蔗滤泥、桐麸的联合高温好氧堆肥,堆制21 d和26 d时,三种腐熟度指标未全部显示堆肥腐熟;堆制31 d时,C/N比为18.55,T值为0.59(小于0.6),发芽指数GI为93.7%(大于80%)。从温度、发芽指数和C/N比三个指标均可认为堆肥已达到腐熟。 The mature indices of composting transformation during co-composting of aniseed marc, filter mud of sugarcane and tung seed meal were studied by analyzing the pattern of temperature, carbon-to-nitrogen ratio（C/N）and the seed germination index（GI）at different stages. The results were as follows：the seed germination index（G1）were available to evaluate maturity of the co-eomposting of aniseed marc, filter mud of sugarcane and tung seed meal. The co-eomposting of aniseed marc,filter mud of sugarcane and tung seed meal at initial carbon-to-nitrogen ratio（C/N）of al. 45 reached mature after eomposting for 31 days, when the carbon-to-nitrogen ratio（C/N）was 18.55, the seed germination index（GI） was 93.7 %.
