Introduction and Cultivation Test on the Partial Alphine Plants in Hubei Province

摘要:

摘要：为了在第十届中国国际园林博览会上展示湖北省珍稀特色植物，从湖北宜昌和恩施等地引种珙桐、连香树、刺叶栎、山茱萸、血皮槭等23种高山植物及不同规格和种类的苗木共计176株，通过土壤改良、容器种植、化学试剂促成、搭建遮阳棚、微型喷灌调控温湿度等系列措施进行精细栽培和养护， 1年后共成活135株，其中珙桐成活率为928%，且有5株珙桐在第二年开花；连香树、刺叶栎、山茱萸、血皮槭等的成活率分别为100%，90%，100%和40.9%。本次部分高山植物引种栽培试验为武汉市城市绿化突出地域特色植物提供了指导意义。

Abstract:

Abstracts:To exhibit rare and regional characteristic plants in Hubei province on the 10th China (Wuhan) International Garden Flower Expo (CIGFE),23 kinds of alpine plants were introduced to Wuhan in 2013 from two sites (Yichang and Enshi).The species of these plants included Davidia involucrate, Cercidiphyllum japonicum,Quercus spinosa,Cornus officinalis,Acer griseum and so on.A total number of 176 seedlings with various specifications and types were cultivated andmaintained elaborately using several techniques including soil improvement,container cultivation, chemical enhancement,shedding with covers and adjustment of temperature and humidity with micro-sprinkling irrigation.After the one-year experiment,135 seedlings survived.The survival rate of Davidia involucrate was 92.8%, and five plants of the survived flowered in the next year.In addition,the survival rates of Cercidiphyllum japonicum,Quercus spinosa,Cornus officinalis and Acer griseum were 100%,90%,100% and 40.9%,respectively.These results will provide suggestions on how to give prominence to regional characteristic plants in constructing urbun forest in Wuhan.
