摘  要：
采用自然沉降法对一家企业接种箱进行杂菌含量测定,利用回归分析法对环境中杂菌含量和污染率进行线性回归、二次曲线回归、三次曲线回归,并对得到的回归模型进行检验,研究金针菇菌包污染率随接种环境中杂菌含量变化的规律。结果表明,3种模型的P值均小于0.01,说明3种模型均可以很好地反映环境中杂菌含量与污染率的关系,三次曲线模型的R■值最大(0.997),接近1,且各回归系数达显著水平,因此三次曲线模型最适合表征环境中杂菌含量与污染率的关系,回归方程为Y=0.203-0.489x+0.293x~2-0.014x~3。

摘  要：
In this paper, the law of variation of other microbes content in inoculated environment versus contamination rate of fungi bag has been studied.In order to achieve the objective of this study, natural sediment method was applied to measure other microbes content in inoculation box of one enterprise.Through regression analysis which contain linear,quadric cure and cubic cure on the date of other microbes content in inoculation box and contamination rate, the mathematical model was constructed, and then a statistical test was put to the model.The results showed that the P value of the three models were less than 0.01, all of the model well reflected the relationship between other microbes content and contamination rate, the R■ of cubic model was maximal(0.997) and regression coefficient were distinctness by T testing, therefore, the cubic model can accurately predict the change of the contamination rate according to other microbes content, regression equation was Y=0.203-0.489x+0.293x~2-0.014x~3.
