摘要
通过对比4种不同有机肥对尾叶桉(Eucalyptus urophylla)胸径、树高和地径的影响,分析不同N、P、K含量的有机肥对桉树生长的影响,筛选出最有利桉树生长的有机肥种类。结果表明:处理D即N:P:K为15:5:11时对桉树的胸径和地径增长促进效果最好;处理C即N:P:K为9:11:10时对桉树树高的增长效果最好。
To select the most favorable types of organic fertilizer,the diameter at breast height(DBH),tree height(TH)and ground diameter(GD)of Eucalyptus urophylla treated by four different organic fertilizers were compared and the effects of different organic fertilizers with different N,P and K content on the growth of E.urophylla were analyzed.The results showed that the effect of the treatment D with N:P:K=15:5:11was the best for the growth of DBH and ground diameter of E.urophylla.Treatment C with N:P:K=9:11:10was the best for tree height of E.urophylla.
