Abstract: To explore the effect of additional Chenpi citrus juice treatments on silage quality of stylo and rice straw. Freshly-harvested stylo and rice straw were treated with 0% (control),1%,and 2% Chenpi citrus juice of fresh weight,respectively. After 30 days ensiling,chemical composition and silage indexes of the samples were evaluated,statistically. The results showed that,compared to the control,pH value and ammonia nitrogen content of the stylo ensiled with 2% Chenpi citrus juice were significantly reduced (P<0.05),and the number of lactic acid bacteria and true protein content were significantly increased (P<0.05). However,Chenpi citrus juice had no significant effects on pH value,protein content,and lactic acid content of rice straw. In the groups that added Chenpi citrus juice,the number of Coliform bacteria was decreased. In conclusion,Chenpi citrus juice could improve the silage quality of stylo,the quality of stylo silage with 2% Chenpi citrus juice was better.

摘要: 为了探究陈皮柑(Citrus reticulata cv.Chachiensis)汁对柱花草(Stylosanthes guianensis L.)和水稻(Oryza sativa L.)秸秆青贮品质的影响,本试验在新鲜柱花草和水稻秸秆青贮中分别添加0%陈皮柑汁(对照组),1%和2%陈皮柑汁(试验组),青贮30 d后测定样品的化学成分和青贮指标,并对青贮发酵结果进行统计学分析。结果表明:与对照组相比,添加2%陈皮柑汁柱花草青贮pH值和氨态氮(Ammonium nitrogen,NH3-N)含量显著降低(P<0.05),乳酸菌数量和真蛋白含量显著提高(P<0.05);而添加陈皮柑汁对水稻秸秆青贮的pH值,蛋白质含量,乳酸含量皆无显著影响;添加陈皮柑汁的试验组,大肠杆菌数量皆降低,但差异不显著。由此可知,陈皮柑汁能够提高柱花草的青贮品质,其中,添加2%陈皮柑汁的柱花草青贮品质较好。
