| 摘 要： | 为了解不同施肥处理对普陀樟(Cinnamomum japonicum var.Chenii)、全缘冬青(Ilex integra Thunb.)、红楠(Machilus thunbergii Sieb.et Zucc)3种海岛树种苗木生长及造林效果的影响,设置了7个不同的施肥处理,即(1)N(对照),(2)N+P,(3)N+2P、(4)N+K、(5)N+2K、(6)N+1P+1K、(7)N+2P+2K,于2011年5月至2012年1月观测苗高和地径,并测定植物各部分的生物量。结果表明:3种苗木不同施肥处理下,通过测算苗木质量指数QI可知,在N+1K施肥组合下,全缘冬青的苗木质量最好,而红楠在N+2P+2K的施肥组合下苗木质量最高,普陀樟在N+1P+1K的施肥组合下,苗木质量要好于其他处理。

| Abstract: | To reveal the growth,and planting effect of three island tree species∶Ilex integra,Machilus thunbergii,Cinnamomum japonicumvar.chenii,a field experiment was conducted using tree seedings on nursery land of Zhou Shan Forestry Institute in 2011to compare seven fertilizer treatments：N（CK）,N＋P,N＋2P,N＋K,N＋2K,N＋1P＋1K,andN＋2P＋2K.Seedling height,ground diameter and biomass were also measured.Through calculating the seedlings quality index of tree species,the results showed that the treatment of N＋1Kwould be the optimal level for Ilex integr,however,Machilus thunbergii Sieb had the optimal quality with N＋2P＋2K,and under the treatment with N＋1P＋1K,Cinnamomum japonicumvar.Chenii seedlings had the best quality. |
