摘要
以引自河南的14个绿化树种的苗木为试验材料,在银川地区进行引种试验观察.通过对苗木栽植后的成活、越冬保存、物候、生长等情况进行分析,前期的试验结果初步表明:紫叶矮樱、红叶臭椿、金枝国槐3个树种的生长表现好,其苗木的保存率高,枝条抽干率低;美国红枫、金脉连翘、金叶接骨木、美国红栌、黄瑞木、红花七叶树、北海道黄杨的枝条抽干率较高,表现一般;金边黄杨、金叶小檗、金叶连翘的保存率低,表现较差.
The introduction experiment of 14 tree species for afforesting was introduced into Yinchuan with their seedlings introduced from Henan province. According to the survival rate, over-winter preserving rate, phenology and growth situation of the introduced seedlings, the seedlings＇ growth performance of Prunus × Cistena ‘Pissardii＇, Ailanthus altissima. ‘Hong Ye＇ and Sophora Japonic. ‘Golden Stem＇ were great in the experimental site, because their over-winter preserving rates were higher but branch withering rates were liver. But the seedlings growth performance of Euonymus japonicus L. f. aureo-marginatus Rehd. , Berberis thunbergii. ‘Aurea’ and Forsythia koreana. ‘Sun Gold＇ were not good because of lowest preserving rates, and the seedlings’ growth performance of other tree species （Aesculus × carnea ‘Briotii＇, Forsythia teoreana. ‘ Aureo-reiticulata’, Sambucus canadensis. ‘ Aurea ＇ , Euonymus japonicus. ‘ Cu zhi ＇, Acer × freemanii-Jef fersred , Cotinus coggyria. ＇Royal PurpleS, Adinandra millwttii, Ginkgo biloba L. ） were not too bad that they need special protection for over-winter. Further research for this introduction experiment is still on going.
