立体绿化花卉优良品种栽培选择试验

<title>Selection of plant species suitable for urban vertical greening

对9个立体绿化花卉品种栽培选择试验结果表明:扶芳藤[Euonymusfortunei(Turcz.)Hand. Mazz.]、常春藤[Hederanepalensisvar.sinesis(Tobl.)Rehd]、络石[Trachelospermumjasminoides(Lindl.)Lem.]、假连翘(DurantarepensLinn.)、爬山虎[Parthenocissustricuspidata(Sieb.etZucc.Planch.]、迎春花(JasminumnudiflorumLindl.)等6个品种生长最佳。这6个品种在可控温培养箱中,在高温湿润时能耐45℃,在高温干旱时能耐40℃的高温,时间长达30d左右;低温在-9℃时茎尖有轻度冻害。在实栽地(上午10时左右),温度达60℃时未见有灼伤出现;低温达-10～-11℃时仍然能生存。同时,它们的耐土壤瘠薄能力强,适应pH值幅度大(0 5～0 8)。利用组织培养和全光照喷雾扦插等方法育苗,均可获得很高的成活率。

<Abstrcat>Of nine plat species available for urban vertical greening,six species viz.Euonymus fortunei(Turcz.)HandMazz.Hedera nepalensis var.sinesis(Tobl).Rehd,Trachelospermum jasminoides(Lindl.)Lem,Durana repens Linn,Parthenocissus tricuspidata(Sieb.et Zucc.)Planch and Jasminum nudiflorum Lindlgrew best.During the period of temperaturecontrolling experiments these six plant species concerned grew rather well at 45 degrees Celsius and could with stand drought for about thirty days at 40 degrees Celsius.At the open planting lot these plants were not visibly scorched up to about 60℃(measured at ten Oclock in the morning).There was a freeze injury at nine or ten degrees of frost in these species.By means of plant tissue culture technique and the nursing method of fullday light with moisturekeeping,very high survials could appear in all.
