目的:研究不同类型含氮化合物对鸡骨草生长和结瘤的效应.方法:在盆栽鸡骨草幼苗接种根瘤菌后,分别用KNO3,NH4NO3,(NH4)2SO4作为氮源配制不同氮浓度的营养液补充水分和营养.培养70 d后,测定植株生长和结瘤情况.结果:含氮化合物对鸡骨草的营养生长有不同程度的促进作用,其中以(NH4)2SO4和NH4NO3的效果最好;它们对鸡骨草结瘤固氮的抑制效应也是明显的,其抑制效应的大小顺序为:NH4NO3＞(NH4)2SO4＞KNO3;KNO3处理以及低浓度的(NH4)2SO4和NH4NO3不影响鸡骨草植株正常结瘤,高浓度的(NH4)2SO4和NH4NO3处理严重抑制结瘤或不能结瘤.结论:铵态氮对鸡骨草结瘤固氮的抑制能力较强,减少铵态氮肥的使用有利于充...

Objective： The research aimed at the effects of different nitrogenous compounds on growth and nodulation of Abrus cantoniensis. Method： After the seedlings of the herb were inoculated with rhizobia in potted culture, they were supplied with nutrition solutions which contained the three nitrogenous compounds, KNO3, NH4NO3, （NH4）2SO4 of different nitrogen concentration. The growth and nodulation of seedlings was determined after 70 days. Result： Different nitrogenous compounds were able to enhance the vegetable growth of seedlings variously....
