| 中文摘要: |
| 发酵床垫料的选择是发酵床养殖推广的重要环节,垫料原料的选择、管理等直接关系到垫料的有效利用,为此连续采集南京六合发酵床养殖基地4个月的垫料样品,对其中有机质、纤维素、半纤维素、木质素及C/N等进行了测定.结果发现,C/N受垫料组成成分的影响,以稻壳和木屑为原料的垫料中分别添加酒糟(垫料Ⅱ)、菌糠(垫料Ⅲ),其C/N下降要快于以稻壳和木屑为原料的垫料(垫料Ⅰ).经117 d的使用,垫料Ⅰ的纤维素、半纤维素、木质素的降幅分别为36.12%、25.12%、18.35%,均小于垫料Ⅱ的48.37%、48.16%、31.66%和垫料Ⅲ的49.42%、56.6%、32.69%;垫料Ⅰ、垫料Ⅱ、垫料Ⅲ的纤维素占对应有机质的百分比分别下降1.77%、3.11%、2.19%;垫料Ⅰ的半纤维素占有机质的百分比上升0.66%,而垫料Ⅱ和垫料Ⅲ的半纤维素分别下降2.57%和3.38%;木质素占有机质的百分比分别上升5.36%、5.26%和3.88%. |
| 英文摘要: |
| Selection and management of bedding materials are important not only for the popularization of bio-bed pig raising, but also for effective utilization of bedding materials. Organic components of bedding materials, including cellulose, hemicellulose, lignin and C/N, were measured by continuously sampling at different depths of fermentation beds for 4 months in a pig-raising base, Liuhe Nanjing. The results showed that C/N was affected by material composition. The decline rates of C/N in the materials containing rice husk and wood sawdust were faster with adding distillers(Litter Ⅱ) and fungus chaff(Litter Ⅲ) than those without distillers or fungus chaff(Litter Ⅰ). During the experiment of 117 days, cellulose, hemicellulose and lignin in Litter I were decreased by 36.12%, 25.12% and 18.35%, respectively, which were respectively less than those in Litter Ⅱ(48.37%, 48.16%, 31.66%) and Litter Ⅲ(49.42%, 56.6%, 32.69%).The percentage of cellulose of total organic components reduced by 1.77%, 3.11%, 2.19%, in Litter I, Litter Ⅱ and Litter Ⅲ, respectively. The percentage of hemicellulose in Litter Ⅰ increased by 0.66%, while that in Litter Ⅱ and Litter Ⅲ decreased by 2.57% and 3.38%. However, the percentages of lignin increased by 5.36%, 5.26%, and 3.88% for the LitterⅠ,Ⅱ, and Ⅲ. |
