摘要
在瑞昌市引进栽培了11个不同地理种源的2 a生香椿实生苗,造林后1 a调查分析各种源幼林期生长差异,发现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。
The two-year-old Seedlings of Toona sinensis from 11 geographical provenances were introduced and cultivated in Ruichang city, Jiangxi and the annual growth of young seedlings were investigated and analyzed in this paper. The results showed that there were significant differences of tree height and basal diameter between provenances of T. sinensis. Based on the height and basal diameter growth and the survival rate as well as the disease and insect pest occurrence of various provenances, the two provenances, Fujian Xiapu provenance and Hunan Donko provenance, were primarily selected as superior provenances in Jiangxi.
