摘要：

为将水葫芦渣资源饲料化利用，本试验将水葫芦渣与麦麸混合青贮，通过感官品质评分确定青贮的效果。试验设6个处理组：处理组1~3添加青贮发酵菌，且麦麸混合比例为0%、20%、30%；处理组4~6不使用发酵菌，麦麸混合比例0%、20%、30%。连续测定0~22天混合物料pH值，结果显示：青贮6~16天，处理组1~3物料pH值显著小于(P<0.05)处理组4~6；青贮18~22天，处理组2和3物料pH值显著小于处理组1；第18天，除处理组4外，其他处理组pH值均降至5.0以下。因此，对第18天青贮物料进行感官评分，结果显示：处理组2、3、6青贮等级为“优等”。以上结果表明：20%麦麸与水葫芦渣混合青贮18天，并添加青贮发酵菌，混合青贮物料感官品质优异。

Abstract:

The objective of this experiment was to study the effects of Eichhomia crassipes residuals ensilage mixed with wheat bran by organoleptic scorings for livestock feedstuff utilization. Six treatment groups were including as follows: Group 1 to 3 adding of zymophyte and 0%, 20%, 30% ratios of wheat bran, and Group 4 to 6 adding of 0%, 20% and 30% ratios of wheat bran only. During the ensiling periods of 6 to 16 days, the pH values of Group 1, 2 and 3 were lower (P<0.05) than those of Group 4, 5 and 6. The pH values of Group 2 and 3 were lower than those of Group 1 from 18 to 22 days of ensiling. The pH values of all treatment groups were decreased to below 5.0 after 18 days of ensiling expect of Group 4. Therefore, the organoleptic properties by scoring were determined at 18 days of ensiling. The results showed that Group 2, 3 and 6 graded level of “Superiority”. These findings proved that Eichhomia crassipes residuals mixed with 20% wheat bran could improved the organoleptic properties of the mixing ensilages with the addition of zymophyte within 18 days.
