摘　　要：按照二次回归正交设计方法,设置5个水平的栽培基质及攀援角度。拟合二次回归方程,并进行模似寻优。得出常绿直立生长的扶芳藤类型在攀援近90°角度的物体时生长速度最快,适宜于立体绿化;而冬季叶色变红的匍匐生长类型的扶芳藤在攀援近50°角度的边坡时生长速度最快,适宜于边坡绿化和沙地治理。栽培基质均适宜于沙与粘土的比例近似为2:1的沙性土壤类型。The research designed 5 levels of substrates and climbing angles according to quadratic regression factorial experiment,fitted quadratic regression equation,and selected good plants.The result is the evergreen and erective type of Euonymus fortunei grows fastest with 90o climbed object.This type is fit for stereo vires-cence.The creepy type with red leaves in winter grows fastest with 50o climbed object;All kinds is suit to planted in the substrate with 2:1 rate of soil and sand.This type is fit for slope virescence and sandland con-trol.
