摘　　要：为对比不同种源杉木第3代种子园实生裸根苗当年造林生长状况,采用6个国家级林木良种基地1年生杉木第3代种子园实生裸根苗木造林。于2021年2月对各种源测定树高和地径,测算树高和地径相对苗期的增长,结果表明:6个种源在造林生长1年时,从树高、地径、高径比和同比增长综合对比分析,华侨种源表现最好,其次为官庄种源、将乐种源和卫闽种源。In order to compare the afforestation growth of bare root seedlings in the third generation seed orchard of Chinese fir from different provenances.The third generation seed orchard of Cunninghamia lanceolata in one year was used for afforestation.In February 2021,tree height and ground diameter were measured.The growth of tree height and ground diameter relative to seedling stage was calculated,The results show that:When the six provenances were planted for one year,the growth rate of the six provenances increased.Based on the comprehensive comparative analysis of tree height,ground diameter,height diameter ratio and year-on-year growth.The overseas Chinese provenance was the best,followed by Guanzhuang provenance,Jiangle provenance and Weimin provenance.
