摘要
采用控根容器和无纺布袋容器进行复叶槭容器苗施肥试验,研究了不同氮、磷、钾施用水平对复叶槭生长的影响.结果表明,不同的氮、磷、钾施用水平对复叶槭容器苗的胸径生长量、根系生长量有显著影响,对复叶槭根系在径级0<l<1.0 mm数量增加显著,对高生长影响不显著,以施用复合肥[m(N)∶m(P)∶m(K)=1∶1∶1]处理的效果最好,但2种容器对育苗效果影响不大,生产上选用无纺布袋更为合适.
The effects of different fertilization levels of N, P and K on growth of Acer negundo seedlings were studied by two sorts of containers, i. e. , root-controlling container and non-woven fabric, in field culture conditions. The results indicated that there was remarkable influence between the different fertilization levels of N, P and K on DBH growth quantity of 0 - 1.0 mm root of Acer negundo growth. The optimal fertilization ratio of N, difference between root-controlling container and root growth. And there was a significant increase in seedlings. But there was no significant difference in height P and K was 1： 1： 1. However, there was no significant seedlings and non-woven fabric container seedlings. It was more appropriate to selects the non-woven fabric as container in fertilization levels.
