Four nitrogen compounds including CO(NH_2)_2,NH_4HCO_3,NaNO_3 and NH_4NO_3 were chosen to study the influences on the agricultural characters, physiological metabolism, officinal component in potted and field experiments.

• 本研究选用有机态氮(CO(NH_2)_2)、铵态氮(NH_4HCO_3)、硝态氮(NANO_3)、混合态氮(NH_4NO_3)四种氮源，采用盆栽试验和大田试验，研究不同氮源对鸡骨草农艺性状、生理代谢以及药用成分等方面的影响。 主要结果如下：
