摘要
采用大田试验,研究10个不同氮磷配施对党参4个生理指标(根粗、根长、根鲜干质量)和3种活性成分(党参炔苷、紫丁香苷和苍术内酯Ⅲ)的影响。结果显示,氮磷肥料施入量不同,对党参根部生长及3种活性成分质量分数会造成不同的影响。党参根长最优处理为尿素120kg/hm2、磷酸二铵375kg/hm2(N1P3);尿素150kg/hm2、磷酸二铵300kg/hm2(N2P2)最利于党参根部的增粗及根鲜干质量的增长;最适宜党参炔苷及紫丁香苷积累的施肥处理为N1P3;苍术内酯Ⅲ质量分数在尿素120kg/hm2、磷酸二铵225kg/hm2(N1P1)水平下达到最大值。结果表明,施用氮磷肥有利于党参根系生长及党参炔苷、紫丁香苷、苍术内酯Ⅲ的积累,处理N1P3及N2P2效果最为突出。
This study aimed to explore the effect of ten different nitrogen and phosphorus fertilizer treatments on four physiological indexes(root width,root length,root fresh mass and root dry mass)and mass fraction of three active components(lobetyolin,syringin,and atractylenolideⅢ)of Codonopsis pilosula through field experiment.The result showed that different nitrogen and phosphorus ratios had different effects on the growth of root and mass fraction of three active components in Codonopsis pilosula.In this experiment,the root length of Codonopsis pilosula reached the maximum under the fertilizer treatment of using urea 120 kg/hm^2 and diammonium phosphate 375 kg/hm^2(N1P3);fertilizer treatment of using urea 150 kg/hm^2,and diammonium phosphate 300 kg/hm^2(N2P2)was most beneficial to the increase of root diameter and root dry and fresh mass of Codonopsis pilosula;the most suitable fertilizer treatment for the accumulation of lobetyolin and syringin was N1P3;mass fraction of atractylenolideⅢreached the highest by using urea 120 kg/hm^2 and diammonium phosphate 225 kg/hm 2(N1P1).This study showed that,N and P fertilizers were beneficial to the root growth and the accumulation of lobetyolin,syringin,and atractylenolideⅢof Codonopsis pilosula,and the best treatment of fertilizer were N1P3 and N2P2.
