摘  要：
采用"盐梯度悬浮法"测定不同发酵时间发酵床垫料的悬浮率,根据垫料表观确定其发酵程度级别,可将30个样品分为4级:一级发酵程度浅;二级发酵程度中等;三级发酵程度深;四级发酵程度很深。结合多元线性回归分析法,确定垫料发酵指数方程为Y=3.9932-0.0046 X1+0.0531 X2-0.0484 X3-0.0083 X4-0.0179 X5-0.0404 X6,判别的相关系数高达94.20%。结果表明:使用该方程测定未知垫料的发酵指数,能快速、准确地判定未知垫料的发酵程度。

摘  要：
Using the method of "Salt gradient Suspension" to determine the suspensions ability of pig litter at different fermentation level in the microbial fermentation bed,as well as,based on the appearance of litter,the level degree of fermentation was established.Thirty samples taken from the piggery were classified into four groups.The first group was characterized with shallow degree of litter fermentation,the second group with medium degree,the third group with deep degree,the fourth group with profound.Combining the multiple linear regression,the mathematical equation of the fermentation index of pig litter was established,that was: Y=3.9932-0.0046X1+0.0531X2-0.0484X3-0.0083X4-0.0179 X5-0.0404X6(r=0.9420).The result indicated that the degree of fermentation of unknown litter were judged fast and accurately by utilizing the mathematical equation to determine the fermentation index of unknown pig litter.
