不同肥料配比对云木香产量的影响

Effect of Different Fertilizer Ratios on Yield of Aucklandia lappa Decne

氮、磷、钾肥及其配比对云木香产量的影响研究结果表明:以氮、磷、钾肥配施或磷、钾肥配施效果为佳,云木香鲜重产量分别可达40 532.41、39 629.63 kg/hm2,单独施用氮、磷、钾肥或氮磷、氮钾肥配施的效果相对都较差,云木香鲜重产量为28 865.74～35 763.89 kg/hm2。3种大量元素对云木香鲜重效应的大小依次是磷、氮、钾,说明磷、氮是云木香根产量形成的最主要元素。

To study the effect of different nitrogen, phosphorus and potassium fertilizer and their ratios on the yields of A ucklandia lappa Decne.. The results showed that with N,P,K combined application and P,K combined application, the effects on yields of A ucklandia lappa Decne.were good. The yields were 40 532.41,39 629.63 kg/hm^2,respectively. With N,P,K uncombined application or N,P combined application,N,K combined application, the effects were bad and the yields were 28 865.74-35 763.89 kg/hm^2.The effects of three macroelements on fresh weight of A ucklandia lappa Decne. were as followed ： P〉N〉K,it indicated that N and P were the most important elements during the yield formation of Aucklandia lappa Decne..
