摘要
基于北方城市地被植物资源较为缺乏的现状,从平凉崆峒山引种维西堇菜,栽培于兰州达家台苗圃基地,待翌年返青后观察并统计其物候期、观赏性状及繁殖特性。结果表明:引种的维西堇菜能够正常生长和开花结实,开花早,花期长,绿期长达200d,且具有良好的观赏价值;其种子在20℃时有较高发芽率、发芽势、萌发值和活力指数,且分株繁殖成活率高达91%。因此可作为良好的早春地被植物在北方城市园林绿化中进行推广。
Considering the lack of ground cover plant in the northern cities,Viola monbeigii introduced from Kongtong Mountain and cultivated in Dajiatai Nursery base of Lanzhou last year,and was investigated after turning green,with the statistics of phenological period,ornamental characters and breeding characters.The results showed that the introduced V.monbeigii grew and developed normally,with earlier flowering,longer blossoming period,green-up periods more than 200 days and the ornamental value at a high level.The seeds showed the highest germination percentage,germination energy,germination value and vigor index at 20℃;in addition,the division reproduction survived at the rate of 91%.Therefore,it was worthy to be utilized at landscape as ground cover plant in early spring in the northern cities.
