| 摘 要： | 本文对杉木地理种源第一次试验21个试验点上19个种源的六年生幼林和第二次试验45个试验点上43个种源的三年生幼林的生长发育及适应性状进行分析,评定各种源的优劣以及与环境的互作。研究表明:种源间差异极显著,如六年生幼林材积的选择效果平均达20％,优劣种源间平均相差3.3倍。根据生长量、稳定性、开花结实和耐寒性等指标,综合评定选出南岭山地为我国杉木的优良种源区。同时,依据各造林区试验结果,初步确定能获得明显增产效益的优良种源,并提出了杉木种子的调拨意见,定出可作为我国杉木良种基地的最优种源区域。

| Abstract: | A nationwide provenance trial was organized with 19 and 43 seedlots on 21 and 45 sites respectively for two experiments with Chinese fir Cunninghamia lanceolata (Lamb.)Hook and assessment was made on development and adaptability at the age of 6 years and 3 years in order to find out the relationship between better provenances and genotypesites. It was found out that there were significant differences between different provenances in standing volume.The selective efficiency of average volume reached 20%. The standing volume of the best provenance is 3.3 times more than that of the worst. According to their growth rate, stablity, characteristics of flowering and seeding and ability to resist frost, the geographic population, naturally occuring in South Ranges, was considered to be the best provenance and a number of better provenances were also identified to suit different types of site for main planting areas of the species. It was also suggested that the research results can be followed to use the seeds properly for establishing plantations under different ecological conditions in China. |
