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。

Chromatic Determination of Fermentation Stages for Microbial Fermentation Bed in Pig Pan |

Abstract: | Using a TES-135A color meter,1 60 samples of bedding material from the microbial fermentation beds in pig pans were measured.The chromaticity data were fed to the Hunter's color difference formula,△E=[(△L)2 +(△a)2 +(△b)2 ]1/2,to obtain the △E value.Based on the average value (μ)and dispersion degree (σ)of △E, the stages of fermentation of the bedding material were classified.The 1 st stage ranged from 0 to μ-2σ,the 2 nd stage from μ-2σto μ,the 3 rd stage from μ to μ+2σ,and the 4 th stage beyond μ+2σ.Subsequently,the apparent color, humidity,odor, and degree of decomposition were determined for samples from each fermentation stage. A regression analysis showed a high correlation between the colorimetric measurements and the observations suggesting the color meter might be used as a means to rapidly determine the fermentation stages of a microbial fermentation bed in a pig pan. |
