摘　　要：为探索不同施肥量对杉木(Cunninghamia lanceolata)第3代种子园实生容器苗当年造林生长的影响,2019年在福建省沙县官庄国有林场杉木新造林地,采用150g/株、250g/株、350g/株和不施肥对照(CK)4个处理,进行了施肥比较试验。结果表明:与对照相比,各施肥处理均显著促进了杉木株高、地径的增长,其中以350g/株施肥处理杉木的株高最高、地径最大,分别为62.2cm、12.2mm,比CK增长60.3%、54.4%。In order to explore the effect of different fertilization rates on the growth of container seedlings in the third generation seed orchard of Cunninghamia lanceolata,In 2019,the author conducted a comparative test of Fertiliza⁃tion on the new Chinese Fir Plantation in Guanzhuang state-owned forest farm,Shaxian County,Fujian Province,The results showed that:compared with the control treatment,fertilization significantly promoted the growth of the to⁃tal height and ground diameter of Chinese fir.The maximum of the total height and ground diameter of Chinese fir was 62.2cm and 12.2mm respectively,and the relative CK increased by 60.3% and 54.4%。
