对全国27个红椿种源2年生林分的生长进行测定,分析比较不同种源适应性和生长节律。结果表明:(1)云南普洱、广东云浮、云南保山、西双版纳、云南楚雄、广西西林、广西隆林、广东韶关种源保存率较低。(2)4~5月红椿树高生长较快,树高生长量占年树高生长量的41%,6月份为红椿树高持续快速生长期,其树高生长量占年树高生长量的36%,9至10月份树高生长总体趋于缓慢;6月份为地径快速生长期,其地径生长量占年地径生长量的35%,8月份地径生长缓慢,仅占16%;不同种源树高、地径生长有极显著差异,可开展种源的早期选择。
對全國27箇紅椿種源2年生林分的生長進行測定,分析比較不同種源適應性和生長節律。結果錶明:(1)雲南普洱、廣東雲浮、雲南保山、西雙版納、雲南楚雄、廣西西林、廣西隆林、廣東韶關種源保存率較低。(2)4~5月紅椿樹高生長較快,樹高生長量佔年樹高生長量的41%,6月份為紅椿樹高持續快速生長期,其樹高生長量佔年樹高生長量的36%,9至10月份樹高生長總體趨于緩慢;6月份為地徑快速生長期,其地徑生長量佔年地徑生長量的35%,8月份地徑生長緩慢,僅佔16%;不同種源樹高、地徑生長有極顯著差異,可開展種源的早期選擇。

The growth of 2-year-old Toona ciliate of 27 provenances were tested.In addition,the adaptability and growth rhythm of different Toona ciliate provenances were analysed.The results showed that:(1)The preservation rates were low in Yunnan Pu Er,Guangdong Yunfu,Yunnan Baoshan,Xishuangbanna,Yunnan Chuxiong,Guangxi Xilin,Guangxi Longlin,Guangdong Shaoguan.(2)The height growth was fast in April to May,when the height growth accounted for 41% of the total height growth.The fast growth period of plant height was in June,when the height growth accounted for 36% of the total height growth.The slow period of plant height appeared in September to October.The fast growth period of basal stem diameter was in June,when the basal stem diameter growth accounted for 35% of the total basal diameter growth.The basal stem diameter growth was slow in August.There were significant differences in tree height and basal stem diameter,which could carry out the early selection of different provenances.
