摘要
在瑞昌市引进栽培了11个不同地理种源的2年生香椿实生苗,造林后1年调查分析各种源幼林期生长差异,发现香椿各种源幼林树高生长量存在着显著差异,香椿不同种源单株之间的树高与地径生长量变异幅度较大。综合其树高、地径生长量与成活率、病虫害状况,初步选出福建霞蒲和湖南洞口2个种源为适宜江西栽培的优良种源。
11 two-year-old Seedlings of Toona sinensis from different geographical provenance were introduced and cultivated in Ruichang city, the growth variation of young growth period of different provenances were investigated and analyzed after planting one year, there were significant differences of young plantation tree height increment among different provenances of Toona sinensis. Integrated the growth performance of beight, ground diameter increment, survival rate and pest status, the coefficient of variation of the height and ground diameter between the different provenance reach variation range greatly, the two provenances of Fujian Xiapu and Hunan Donko were primarily selected as superior provenance that suitable for cultivation in Jiangxi province.
