熵权赋权法灰色系统理论在大花蕙兰(Cymbidium hybridium)品种综合评价中的应用初探

Primary Application of Entropy Weight-based Gray Systematic Theory to Integrated Evaluation in Cymbidium hybridium

通过运用熵权赋权法灰色系统理论对17个大花蕙兰品种观赏性及适应性进行了综合评价,以期选出适合四川地区栽培的大花蕙兰品种。结果显示,黄金薄荷、浪漫、红颜关联度值较高,均大于0.6,综合性状较好;红玫瑰、红霞、黄奥斯、爱我、苏珊娜、钢琴家、金小姐和艳后关联度值大于0.5,小于0.6,综合性状表现一般;绿洲、爱神、阳春4号、梦境、马州利卡、粉曼娜关联度值小于0.5,综合性状表现不好。其中黄金薄荷和浪漫关联度值基本达到0.7,表明这2个品种适合四川地区栽培。评价结果与生产实际相符,说明熵权赋权法的灰色系统理论可以用于大花蕙兰资源的综合评价。

In order to select suitable Cymbidium hybridium for Siehuan province, entropy weight-based gray systematic theory was used to e- valuate 17 Cymbidium hybridium according to their ornamental and adaptability. The results showed that C. SkyMint Patty, C. Sherry Ro- mance and C. Popini had the best performance with the higest interrelated degree （ri 〉0.6） ; C. PrettyRosa, C. Nobuko, C. Lo rely Bunn ＇ Othello＇, C. Love me, C. Chsanne, C. Pianist, C. MissKim and C. Hohoemi Queen had general performance with interrelated degree （0.5 〈 ri 〈 0.6） ; C. A One, C. Aguri, C. YangChun Four, C. Wonderland, C. Majolika and C. GreatFlower＇ Madonna＇ had low interrelated degree （ ri 〈 0.5 ） and bad performance. The interrelated degree of C. SkyMint Patty and C. Sherry Romance was 0.7, which showed that the two varieties were fit to Sichuan province. The result of gray systematic analysis was consistent with production practice, which indicated that entropy weight-based gray systematic theory could be used in integrated evaluation of Cymbidium hybridium.
