红河引种云油茶新品种的早期适应性研究

2009～2010年从广南油茶研究所引种云油茶3号、4号、9号、13号、14号5个优良品种到金平和绿春两地进行田间试验,以广南油茶研究所苗圃地5个油茶新品种的生长情况为对照,分析了引种地其幼林早期的成活率、保存率、生长量及对干旱和低温适应性。研究结果表明:云油茶新品种早期在金平和绿春生长正常,当地的环境条件能满足其生长,金平试验地造林1年时的苗高、地径和春梢生长量分别为广南油茶研究所苗圃地同龄大苗的88.7%、95.3%和94.9%,绿春试验地造林2年时3项指标分别为广南的91.1%、92.7%和91.8%;并且在两地都表现出很强的抗寒和抗旱能力,但金平试验地虫害的发生较严重。

Early Adaptability of ‘Yunyou’ Series of Camellia oleifera Introduced to Honghe Prefecture

From 2009 to 2010,five superior Camellia oleifera varieties namely ‘Yunyoucha 3’,‘Yunyoucha 4’,‘Yunyoucha 9’,‘Yunyoucha 13’ and ‘Yunyoucha 14’ were introduced to Jinping county and Lvchun county of Yunnan province.Taking the growth performance of the five new varieties in nursery of the Oil Tea Research Institute of Guangnan County as the control,the survival ratio,conservation ratio,growth increment and adaptability to drought and low temperature of the introduced plants.The experimental results indicated that these five new varieties could grow normally in Jinping and Lvchun,one year old trees planted in Jinping,the growth of height,basal diameter and spring shoot were 88.7 %,95.3 % and 94.9 % respectively of Guangnan;two years old trees planted in Lvchun,these three indexes were 91.1 %,92.7 % and 91.8 % respectively of Guangnan.Basically,these five varieties showed promising ability to drought and cold,however the pest in Jinping was a prominent problem.
