摘要： 为促进蚕桑副产物资源化利用，以等质量混合的桑枝和蚕沙为原料进行堆肥，探讨桑枝初始粒径对堆肥过程及腐熟效果的影响。结果表明，小粒径桑枝(<1 cm)可更好提高堆体积温并维持堆体温度，有效促进有机碳的降解；较大粒径桑枝(>1 cm)的堆体具有适宜的容重，在堆肥过程中能够显著促进半纤维素、纤维素的降解，C/N下降幅度大，从而使有机物质分解更彻底，腐熟效率高。堆肥结束后，其中C组（粒径>2 cm）堆体的腐殖质、速效氮磷钾含量及总磷钾含量均显著高于其他组别，表明其堆肥品质最佳。综合来看，桑枝蚕沙堆体（等质量混合）桑枝碎段控制在2~7 cm有助于（半）纤维素的降解和堆肥品质的提高。

Abstract:

To promote the resource utilization of sericulture byproducts, this study investigated the effects of initial particle size of mulberry branches on the composting process and compost maturity by mixing mulberry branches and silkworm faeces in equal mass. The results showed that although smaller particle sizes (<1 cm) could better increase the compost piles temperature and maintain it at a higher level, while also effectively promoting the degradation of organic carbon, piles with larger particle sizes (>1 cm) had appropriate bulk densities, which significantly promoted the degradation of hemicellulose and cellulose during the composting process. These larger-particle-size piles also exhibited a greater decrease in C/N ratio, indicating more thorough decomposition of organic matter and higher maturity efficiency. After composting, group C (particle size>2 cm) had the highest contents humus, available nitrogen, phosphorus, potassium, and total phosphorus and potassium, resulting in the best compost quality. Overall, controlling the mulberry branch particle sizes at 2-7 cm in compost piles made from a mixture of mulberry branches and silkworm faeces (at equal mass) facilitates the degradation of (hemi) cellulose and improves of compost quality.
