摘  要:
以凤仙花苗为试材,研究不同氮素形态处理对其光合色素含量及光合荧光参数的影响。结果表明:氮素处理均能有效促进叶绿素积累,且T5处理(全铵态氮,100%NH4+)时光合色素含量显著高于其它处理组。和CK相比,Fv/Fm、Yield、ETR、qP值有所提高,且T3处理(硝铵比50∶50)时最显著。因此,适量增加硝态氮比例,有利于促进凤仙花生长、且硝铵比为50∶50较好。

摘  要:
Using Impatiens balsamina seedlings as the materials,the impact of different nitrogen forms on chlorophyll content and photosynthetic fluorescence parameters of Impatiens balsamina were studied.The results showed that dealing with nitrogen forms could effectively promote the accumulation of Impatiens balsamina chlorophyll,besides,in T5(100% NH4+),the contents of photosynthetic pigment obviously rise much higher.In T3(NO3-∶NH4+=50∶50),level of Fv/Fm,Yield,ETR,qP was much higher comparing with CK.Thus,appropriately increasing proportion of tric nitrogen was good for Impatiens balsamina's growing,NO3-∶NH4+ ratio of 50∶50 was better.
