摘要：目的:研究施钾量对不同生长期当归根系中藁本内酯,洋川芎内酯A,洋川芎内酯H,洋川芎内酯I,阿魏酸松柏酯,丁烯基苯酞及欧当归内酯A等苯酞类成分含量动态的影响,为合理制定当归施用钾肥方案提供科学依据。方法:在大田试验条件下,研究施K_2O量为0 kg·hm^(-2)(K_0),150 kg·hm^(-2)(K_1),300 kg·hm^(-2)(K_2),450 kg·hm^(-2)(K_3),600 kg·hm^(-2)(K_4)和750 kg·hm^(-2)(K_5)对当归苯酞类成分动态含量的影响,采用HPLC测定不同生长期当归根中上述7种成分含量。结果:施钾并不改变当归根中苯酞类成分含量随生长期变化而变化的趋势;不同施钾量对当归苯酞类成分含量有显著影响(P<0.05)。在本试验条件下,K_2O以450 kg·hm^(-2)处理对增加当归根中苯酞类成分含量的效果最好。结论:施钾能提高当归根中苯酞类成分含量,但施钾不会改变整个生育期内当归根中苯酞类成分含量的总体变化趋势。
Objective： To investigate the effect of potassium nutrition levels on contents of ligustilide, senkyunolide A, senkyunolide H,senkyunolide I, coniferylferulate, n-butylidenephthalide and levistilide A from Angelicae Sinensis Radix in different growth periods, and provide a theoretical basis for reasonably formulating theapplication scheme of potassium fertilizer in the standardized production of Angelicae Sinensis Radix. Method： In field cultivation experiment conditions, the effects of K2O of 0 kg·hm^-2 （K0）, 150 kg·hm^-2 （K1）, 300 kg·hm^-2 （K2）, 450 kg·hm^-2 （K3）, 600 kg·hm^-2 （K4） and 750 kg·hm^-2 （K5） on phthalides in Angelicae Sinensis Radix were studied. The contents of the above 7 phthalides components during different growth periods in roots of Angelicae Sinensis Radix were determined by HPLC method. Result： Potassium application did not change the variation trend of phthalides constituents along with the growth period in roots of Angelicae Sinensis Radix, but different volumes of potassium fertilizer application had significant effects on the contents of phthalides components（P〈0.05）. Under the experimental conditions, K2O 450 kg·hm-2 had the best effect on the contents of phthalides components in Angelicae Sinensis Radix. Conclusion： The appropriate level of potassium fertilizer can increase the contents of phthalides constituents in roots of Angelicae Sinensis Radix, but did not change the overall dynamic changes trend of contents of phthalides components in the roots of Angelicae Sinensis Radix.
