油茶大砧嫁接名贵茶花品种的效应

Research on Effects of Grafting Rare Camellia with Bigger Stocks of Oil Tea

利用油茶人工林为砧木,采用改良撕皮接技术,嫁接36个茶花品种。分析结果得出,不同茶花品种嫁接成活率有较大差异,其中25个品种嫁接砧成活率平均达到92.3%,亲和性强,7个品种的成活率平均达到88.1%,另有4个品种成活率平均为83.5%。6 a后的生长状况调查表明,早花系列的5个品种、中花系列的7个品种、晚花系列的7个品种树势恢复情况最好,符合园林生产快速培育大规格茶花的要求。

Thirty-six cultivars Camellia japonica L. had been grafted on rootstock of the Camellia plantation by mean of the technology of improved pull budding. Results showed that there was difference in the grafting survival rate of the different kind of camellia cuhivars. The stock survival rate of 25 euhivars reached an average of 92.3 percent, displaying strong affinity. Seven cultivars reached an average of 88.1% survival rate ,and survival rate of fourth cultivars was 83.5%. The investigation of six years later about growth status showed that seven cultivars of early flowering series, seven cultivars of middle series, seven cultivars of late-flowering series manifest the best recovery of tree vigor, adapted for fast-cultivating big tree of Camellia japonica L. .
