摘要
应用单因素方差分析和模糊综合评价,研究蛇床子素和多杀菌素两种生物农药单剂对小麦储藏品质的影响。建立小麦储藏品质变化的模糊综合评价模型,分析储藏4个月和8个月小麦品质多指标动态变化模型,先用极差变换及线性比例变换对指标矩阵进行无量纲化处理,再用夹角余弦法确定权重向量,最后得到模糊综合评价值,并用拉依达检验法检验。结果表明:储藏4个月和8个月的综合评分值H和F均小于2 s(2 s相当于显著水平a=0.05),确定了评价模型的可行性,也表明了各样品差异不显著,即分别拌以0.50、0.75、1.00 mg/kg的1.0%蛇床子素粉剂和0.50、1.00、1.50 mg/kg的0.5%多杀菌素粉剂的小麦样品与不拌药的小麦样品在储藏8个月内的品质没有显著影响,为小麦品质储藏寻求到较为安全的两种生物农药,同时也为粮食品质储藏研究工作提供了一个重要的分析方法。
The effects of two kinds of bio-pesticide, osthole and spinosyn on the storage quality of wheat were studied with one-way analysis of variance(ANOVA) and fuzzy comprehensive evaluation. The fuzzy comprehensive evaluation model was established to evaluate the changes in wheat storage quality. During wheat storage for four and eight months, an index matrix of fuzzy comprehensive evaluation model was constructed. First of all, the index matrix was nondimensionalized with range transformation and linear scaling transformation, and then the weight vector was determined based on angle cosine. Finally, the fuzzy comprehensive evaluation value was achieved by using the Paǔta test method. In this case, the model was of practical applicability. The results demonstrated that comprehensive evaluation values of H and F for 4- and 8-month storage respectively were less than 2 s(2 s is equivalent to a significant level). The quality of wheat in the presence of 0.50, 0.75 and 1.00 mg/kg of 1.0% osthole powder or 0.50, 1.00 and 1.50 mg/kg of 0.5% spinosyn powder was not significantly different from the control during storage for eight months. In a conclusion, osthole and spinosyn are safe for the storage quality of wheat and the fuzzy comprehensive evaluation model could be considered as an important approach to understand quality preservation of grains during storage.
