摘要
采用模糊聚类分析的方法对5个品种饲用玉米(Zea mays)的农艺性状进行聚类分析。结果表明:取λ=0.6644时,5个品种饲用玉米的农艺性状可以分为Ⅰ(好)Ⅱ(中)Ⅲ(差)3个等级,BMS001和BMS002农艺性状归为Ⅰ级,科多八号和科多四号农艺性状归为Ⅱ级,中原单32号农艺性状归为Ⅲ级,结果表明在饲用玉米选择上优先选用BMS001和BMS002;模糊聚类分析方法应用于饲用玉米适宜性筛选评判上,其技术路线是可行的,技术方法是正确的。
The agronomic traits of the five maize varieties were analyzed by fuzzy clustering analysis. The results showedwhen = 0. 6644, the 5 varieties of forage maizes can be divided into three categories of I , lI , and Ill which indicated good, medium and worse. The agronomic traits of BMSO01 and BMS002 were in the class I , the agronomic＇ traits of Keduo 8 and Keduo 4 were in class II , and the agronomic traits of Zhonguandan 32 were in classⅢ. The varieties of BMSO01 and BMSO02 were the best choice. The application of filzzy cluster analysis method in the selection and evaluation of forage maize was feasible.
