| 摘 要： | 以1年生美人蕉为材料，采用5种不同施氮水平处理，对其进行生理生化指标测定。结果表明：1）不同硝态氮水平处理对提高美人蕉叶片中叶绿素a，叶绿素b含量均有影响；随着N水平的增加，在一定范围内美人蕉叶片中的叶绿素含量均呈上升趋势，其中处理B和处理C效果最明显；但是过量施用氮肥反而会抑制美人蕉的正常生长。2）不同硝态氮处理能有效增加美人蕉叶片中POD酶的活性；但浓度过高的硝态氮处理，反而会降低POD酶的活性；试验显示处理A和处理B效果最佳。

| Abstract: | 1 a Canna indica L. as material, by adopting five different ammonia standard, physiological indicators were test- ed. The results showed ： 1. different nitrate ammonias had different effects to the content improve of chlorophyll a and chlo- rophyll b in the leaf. With the increase of the content of the N, the content of chlorophyll increased, and the effect of treat- ment B and C were particularly good, but once over-fertilized, the ammonia fertilizer could restrained the normal growth. 2. all of the nitrate ammonia treatments could effectively increase the activation of POD enzymes, but once the content of ni- trate ammonia treatment was over, the activation of POD enzymes decreased. The test indicated that treatment A and B were the most effective. |
