摘要(Abstract)：

【目的】摸清铁核桃(Juglans sigillata)氮素营养生理特性,为铁核桃幼苗氮肥合理应用提供科学依据。【方法】采用盆栽土培实生苗试验,研究铵态氮、硝态氮和酰胺态氮[CO(NH2)2]及其配比对铁核桃叶片净光合速率(Pn)、蒸腾速率(Tr)、气孔导度(Gs)、胞间CO2浓度(Ci)及叶片光合色素和可溶性糖、淀粉、营养元素等的影响。【结果】NO3--N与NH4+-N按照各50%混合施用时,叶片的Tr、Ci、Gs、Chl.a、Chl.b、Chl.a+b、可溶性糖、淀粉和氮、磷、钾、钙、镁、铁、锰、铜、锌、硼的含量及Pn在所试配比中都最高;单一施用CO(NH2)2、NH4+-N或NO3--N时,上述指标都较低,Pn下降;在各处理中,单一施用NO3--N的叶片气体交换参数指标、光合色素和养分含量和Pn最小。【结论】铁核桃实生苗不具喜NO3--N特性;氮素形态及其配比对铁核桃实生苗叶片光合特性及养分含量影响明显,在NO3--N与NH4+-N的混合比例超过50%或单一施用CO(NH2)2、NH4+-N、NO3--N时不利于铁核桃实生苗叶片光合同化积累及营养元素的吸收。
