摘要
我国依据茶树品种农艺性状进行选育的国家级和省级良种已达300多个,但以综合价值为目标的生态经济型品种筛选尚未见报道。以条形绿茶为例,利用德尔菲法和层次分析法(AHP)对24个茶树品种进行综合评价,筛选出适制优质条形绿茶的生态经济型茶树品种。综合专家打分和对其提出的建议进行小组讨论,形成含6个一级指标和19个二级指标的综合评价体系,其中确定指标的两轮德尔菲法专家积极程度分别为82.5%和100%,专家权威程度分别为0.93和0.90,变异系数(CV)分别为0.19和0.16,肯德尔系数(W)分别为0.296(P<0.05)和0.358(P<0.05)。一级指标权重分别为0.364、0.204、0.128、0.108、0.124、0.072;二级指标权重在0.101~0.805(均通过一致性检验),其中重要性赋值的德尔菲法专家(第三轮)积极程度为100%、专家权威程度为0.91、CV为0.36、W为0.11(P<0.05)。模型综合评价结果表明,龙井长叶、舒茶早、菊花春分别以3.714、3.624、3.581得分位居前三名,是适制优质条形绿茶的生态经济型品种。
More than 300 state-and provincial-level tea plant cultivars have been selected according to the agronomic traits in our country. However, few studies about the selection of eco-economical cultivars through comprehensive value method was reported. In this study, to screen optimal tea plant cultivars suitable for eco-economic strip-green tea, 24 tea cultivars were evaluated using Delphi and Analytic Hierarchy Process(AHP)methods. A comprehensive evaluation system containing 6 first-level indicators and 19 secondary indicators was formed based on the experts’ evaluated scoring and suggestions by a comprehensive discussion. Among them, the experts’ positivity degree of the first two rounds based on Delphi method were 82.5% and 100%, respectively. The degrees of experts’ authority were 0.93 and 0.90, respectively. The Coefficients of Variation were 0.19 and 0.16,respectively. While the Kendall’s W were 0.296 and 0.358, respectively(P<0.05). The weights of the first-level indicators were 0.364, 0.204, 0.128, 0.108, 0.124 and 0.072, respectively. The weights of secondary indicators were between 0.101-0.805(all parameters were passed the consistency test). Among them, the expert positivity, degree of expert authority, Coefficient of Variation and Kendall’s W of the final round were 100%, 0.91, 0.36 and 0.11(P<0.05), respectively. In summary, ‘Longjing Changye’, ‘Shuchazao’ and ‘Juhuachun’ ranked the top three, with scores of 3.714, 3.624 and 3.581, respectively.
