观赏红果冬青在许昌地区的引种及栽培研究初探

Introduction and Cultivation of llex purpuea in Xuchang Area, Henan Province

本研究从湖北随州采集红果冬青的种子,播种于许昌鄢陵地区培养成苗,研究其生长情况,以其优良单株的一年生枝条作为插条,以枸骨为砧木嫁接成苗,统计成活率。综合分析研究结果如下:实验研究了2009年和2010年度的红果冬青的苗木生长情况,其中成活率均达到了85%以上,地径增长分别在1.3cm和2.9cm。株高和冠幅的最大增幅出现在6-8月份,其中株高的最大净增长量分别是2009年8月的18.9cm和2010年7月的18.8cm;冠幅的最大净增长量分别是2009年6月的9.9cm和2010年7月的9.9cm。且红果冬青能够在温度较低的环境下正常生长。同时,对红果冬青的嫁接繁殖方式进行了相关研究:春季以枸骨为砧木的芽接方式,其嫁接苗木成活率90%以上,嫁接苗能够正常生长。初步断定红果冬青能够在许昌地区成功引种。

The study is researching of growing situation on the seed of//ex purpuea which collected in Suizhou,Hubei province and seeded in Yanling, Henan province, t hen growing to seedling. At mean time,we get the survival rate of statistics on grafting of Ilex purpuea on condition that Ilex purpuea Hassk＇s single plant as cutting and I lex cornuta Lindl. et Paxt. as stock. The study analysised of the Ilex purpuea introduction comprehensively. The results of the study are as follows： the experiment researched the growing situation of seedling in 2009 and 2010. The rate of survival reach up to 85%, and increasing height of ground diameter are 1.3cm and 2.9cm.The largest increase of plant height and crown breadth is at June to August. Among them, the largest net growth of plant height is 18.9cm at August in 2009 and 18.8cm at July in 2010. The largest increase of ground diameter is 9.9cm at June in 2009 and 9.9cm at July in 2010. The flex purpuea can survive in cold climates. According to the research of Ilex purpuea grafting modes of reproduction which are using Ilex cornuta Lindl. et Paxt. as stock in Spring, we can find that the survival rate of statistics on grafting reach up to 90%.We can defined preliminary that the introduction of I/expurpuea is succeed.
