| 摘 要： | 比较了三种形态氮素营养（NH4^ -N;NO3^--N;NH4^ -N:NO3^--N=1:1)对彩椒不同生长发育时期有关生理特性的影响，结果表明，彩椒发棵期之前（含发棵期），施用NH4^ -N NO3^--N混合态氮素，效果最好，植株全氮含量、叶片叶绿素含量、净光合速率的测定值最高，硝酸还原酶活性仅次于NO3^--N处理组；同期若单施氮素，则彩椒更易吸收和利用NH4^--N；但发棵期后，单施NO3^--N，各指标的测定值明显高于其它处理。

| Abstract: | In three different nitrogen treatments, the total nitrogen content of colour sweet pepper plant, chlorophyll content, net photosynthetic rate of colour sweet pepper leaves were the highest in the mixture treatment of NH + 4 N+NO - 3 N at seedling and developing stage, though the nitrate reductase activity was lower than in NO - 3 N treatment. At the same time, compared to NO - 3 N, NH + 4 N was easier absorbed. But after developing stage, in NO - 3 N treatment, the values of those indexes above were the highest. |
