摘要:
该文报道了广西特有珍稀濒危植物东兴金花茶在桂林引种驯化的研究结果,包括其播种、扦插繁殖与种苗移植技术及其生长发育特性等。结果表明:引种到桂林中亚热带季风气候区的自然环境条件下,植株能正常生长发育和开花结果,抗寒性较强。采用留1叶的一年生穗条,以100 mg?L1溶液浸泡处理14 h,插于黄泥土基质可获得较高的生根成活率。成龄植株每年抽梢两次,于4月中旬~5月中旬抽一次春梢,7月抽一次夏梢。7月上旬开始现蕾,翌年4月中旬为开花始期,4月下旬为开花盛期,5月上旬为开花末期,果实于12月成熟。研究结果为东兴金花茶的人工栽培提供参考。
Abstract:
Camellia tunghiensis is a rare and endangered plant endemic to Guangxi. This paper reports the introduction and acclimatization of C.tunghiensis in Guilin,including the technologies of sowing,cutting propagation,seedling transplant and its growth characteristic. The plant is adaptable to grow in Guilin and can bloom and seed normally with the stronger cold resistance. It can get higher rooting rate of cutting by using one year shoot with one leaves on the top,dipping the cuttings in solution(100 mg?L1 NAA)for 14 h,yellow soil as medium for cutting bed. Shoot of mature plants grew two times a year in spring and summer. The flowering period was from the early of July to the early of May next year. The fruit of the plant was in December. The result can provide the reference for the artificial cultivation of C.tunghiensis.
