| 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。 |

| Abstract: |
| 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(GI)were available to evaluate maturity of the co-composting of aniseed marc,filter mud of sugarcane and tung seed meal. The co-composting of aniseed marc,filter mud of sugarcane and tung seed meal at initial carbon-to-nitrogen ratio(C/N)of 31.45 reached mature after composting for 31 days,when the carbon-to-nitrogen ratio(C/N)was 18.55,the seed germination index(GI)was 93.7%. |
| Key words: aniseed marc compost maturity C/N seed germination index |
