摘　　要：分别设置了施氮量为05、5、110、2204、40 kg/hm2(尿素)的5种处理;折合尿素0、22、448、81、76 g/株.比较了不同施氮量对黄檗幼苗氮代谢相关酶类的影响.结果表明:N20、N40、N80三个处理的铵态氮和硝态氮含量都显著高于对照,N10处理与对照差一不显著.可溶性蛋白含量可随施氮量增高,与对照处理的差异都达到显著或及显著,但当升高到一定程度时,可溶性蛋白含量不会继续升高.少量施氮的N10处理既能显著提高NR和GS活性,而随施氮量提高,N20、N40、N80处理NR和GS活性的变化不显著.Five different Nitrogen Fertilizer Rate were set to treatment Corktree Seedlings, it is 0,55,110,220,440 kg/ hm2（urea）, which equivalent 0,22,44,88,176 g/plant with urea. The results show that NO3--N and NH4 ＋ -N content with N20, N40, N80 treatment more higher compare with control, while no significant change with N10 treatment. The content of soluble protein in corktree seedlings increased with the rise of nitrogen fertilizer rate until increased to a certain content, presence significant different with control. NR and GS activity in corktree seedlings increased with N10 treatment, whereas there is no significant change with the treatment of N20, N40 ,N80.
