【摘要】：采用TES-135色差仪对微生物发酵床大栏养猪场的160份垫料样本进行色度分析,采用亨特(Hunter)色差公式:△E=[(△L)2+(△a)2+(△b)2]1/2对样本间的色差进行统计分析,结合STDEV算法,根据样本的色差相对于平均值(μ)的离散程度(σ),将垫料的发酵等级分为4级:0△E≤μ-2σ为发酵1级;μ-2σ△E≤μ为发酵2级;μ△E≤μ+2σ为发酵3级;△Eμ+2σ为发酵4级。通过表观颜色、干湿度、味道、腐烂程度等对不同发酵等级的垫料样本进行表观描述,结果显示垫料的色度分析能准确反应垫料的发酵等级。这为垫料发酵等级的快速鉴定奠定理论基础。
[Abstract]:The colorimetric analysis of 160 padding samples from the pig farm of microbial fermenting bed was carried out by using TES-135 chromatic aberration instrument. The color difference formula of Hunter's Hunter was used to analyze the color difference between samples by using the formula E = [(Ln _ 2 (a ~ (2) (bn ~ (2)] _ (1 / 2), combined with the STDEV algorithm, the color difference between the samples was statistically analyzed. According to the dispersion of the color difference relative to the average value (渭) of the sample, the fermentation grade of the cushion was divided into 4 grades: 0: 0 E 鈮，
