摘要
应用灰色系统中的关联分析法对11种引种的冷季型草坪草的绿色期、越冬率、越夏率、质地、盖度、密度、均一性、颜色、触感等9项主要性状进行了分析评估,并探讨了灰色分析在草坪草引种综合评估中的应用。结果表明,在参试的11个品种中,紫羊茅的"派尼"和高羊茅的"野马2"综合性状最佳,草地早熟禾的"爱沃德"最差。
Applying the relevant analysis approach of gray system, the authors analyze and assess the average of the 9 indexes, including the reviving period, green period, over wintering rate, over summering rate, quality, covering rate, density, uniformity, color and tactile impression and study the application of gray analysis in the comprehensive assessment. The results showed that Pernille of Cherving festuce is the best, Award of Kentucky bluegrass the worst and the others in the middle in introduced 11 species.
