摘  要:
本文以西伯利亚百合为研究对象,从硝酸还原酶的活性,可溶性糖的含量,还原性糖的含量,可溶性蛋白质的含量,淀粉酶的活性等多个方面探究了不同氮水平的硝态氮和铵态氮对西伯利亚百合生长发育的影响。从结果看出,在观赏百合栽培过程中硝态氮和铵态氮合理的配比施用,既可使氮素被植物成分吸收利用,也避免了氮素积累所引起的负面效应。

摘  要:
Siberia Lily as experimental material,the effect of NO-3-N and NH+4-N at different concentration on Siberia Lily growth and development were studied from multi-aspects,such as nitrate reductase activtity,soluble sugar content,reducing sugar content,soluble protein content,amylase activtity and so on.Results showed that a reasonable ratio of application of nitric nitrogen and ammonium nitrogen shuold enable nitrogen absorption and utilization by plants,also avoid the negative effects of nitrogen accumulation.
