基于灰色关联度分析的剑江沿阶草建坪质量评定

Evaluation of the Quality of Ophiopogon bodinieri Levl. Jianjiang Based on Grey Correlation Analysis

为筛选适宜的观赏剑江沿阶草建植方法及为新品种合理栽培、推广和应用提供技术支持,采用相同方法不同株行距建植剑江沿阶草草坪,应用灰色关联度分析法对建植草坪的成坪时间、盖度、密度、质地、观赏性5项指标进行分析评估,处理Ⅰ关联度(0.8929)与理想处理最为接近,综合性状优良,其次是处理Ⅱ(0.8232)综合性状表现居中,处理Ⅲ(0.6830)与理想处理相差最大。结果表明,处理Ⅰ(株行距14cm×14cm即49株丛/m^2)建坪效果最优。

To screen suitable methods for planting Ophiopogon bodinieri Levl. Jianjiang and provide technical support for the rational cultivation,popularization and application of new varieties. using Using using the same method,different row spacing was used to establish Ophiopogon japonicus lawn,and the five indexes of turf formation time,coverage,density,texture and ornamental value were analyzed and evaluated by using grey correlation analysis. The results showed that theⅠcorrelation degree（ 0. 8929） was close to the ideal treatment,the comprehensive character was excellent,and the treatment Ⅱ（ 0. 8232） comprehensive character was middle,and the treatment Ⅲ（ 0. 6830） and ideal treatment was the biggest difference. It is concluded that the results showed that the effect of the row spacing of 14 cm × 14 cm/m-2 was better than that of other treatments.
