基于AHP的姜荷花盆栽种质资源综合评价

Comprehensive Evaluation of Potted Curcuma alismatifolia Germplasm Resources Based on AHP

建立盆栽姜荷花品种综合评价体系,为筛选适合规模化设施栽培的优良品种提供依据。通过盆栽试验对20份姜荷花种质的主要品质特性进行观察统计,应用层次分析法和模糊分析法,从观赏价值、资源价值、适应性3个方面建立盆栽姜荷花种质资源综合评价体系。结果表明:确定了盆栽姜荷花种质资源18个评价因子的指标值,其中种质的稀有性、观花期、苞片颜色、苞片与叶位置关系所占比重较大,权重分别为0.1820、0.1467、0.1178、0.0893;依据综合评价得分进行聚类分析,可将20份姜荷花试验种质划分为优、良、一般、差4个等级,最终选出小旋风、樱桃公主、晶莹、荷兰红、鸿运、绿色巧克力6个品种,可以作为产业化应用优先推荐的盆栽优良品种。综合评价结果与实际生产较为相符,表明构建的评价体系可以较好地对盆栽姜荷花的品种进行筛选和分级。

The establishment of the comprehensive evaluation system for the potted Curcuma alismatifolia varieties could provide a basis for screening excellent varieties which were suitable for the large-scale facility cultivation.The main quality characteristics of 20 germplasms of Curcuma alismatifolia were observed and counted through the pot experiment.The comprehensive evaluation system of potted Curcuma alismatifolia germplasm resources was established from the three aspects of ornamental value,resource value and adaptability by using the analytical hierarchy process and fuzzy analysis method.The results showed that the index values of 18 evaluation factors for the potted Curcuma alismatifolia germplasm resources were determined,among which,the rarity of germplasm,flowering viewing period,bract color and the relationship between bract and leaf position accounted for a large proportion,with the weights of 0.1820,0.1467,0.1178 and 0.0893,respectively.The cluster analysis was carried out according to the comprehensive evaluation score,and 20 germplasms of Curcuma alismatifolia could be divided into four grades:excellent,good,general and poor.Finally,six varieties,such as Xiaoxuanfeng,Yingtao gongzhu,Jingying,Helanhong,Hongyun and Lvse qiaokeli,were selected,which could be used as the recommended potted varieties with priority for the industrial application.The comprehensive evaluation results were consistent with the actual production,which indicated that the evaluation system could screen and grade the varieties of potted Curcuma alismatifolia well.
