摘要
对５种施肥措施影响尾叶桉林分生长过程，进行了历时９ａ的定期观测和系统分析，所得出的结论有：施肥既可提高林分产量，又能缩短成材时间；一次性施足基肥的肥效可延续到轮伐期（５～６ａ）；施用Ｎ、Ｐ、Ｋ复合肥比单一肥或两元素的复合肥效果好；只施Ｎ肥效果差，和不施肥结果相近；在不同肥料中，Ｐ肥效应突出。
Periodical investigation and systematic study on the fertilization to Eucalyptus urophylla stand were conducted for 9 years.5 fertilization methods (1.Nil,2.N 100 ,3.P 50 ,4.N 100 P 50 ,5.N 100 P 50 K 50 )were adopted.The main results show that the tree growth can be promoted and the rotation time can be shortened by the application of fertilizer;a plenty of basal dressing can be available in the whole rotation(5～6 years);NPK is the best one in the fertilizer regimes used in fertilizer trials;the effects of various fertilizers are different,of which nitrogenous fertilizer is not effective, but phosphatic fertilizer is outstanding.
