以辽藁本为试材,采用烘干称重和高压液相色谱方法,研究了2年生和3年生辽藁本不同生育时期的生长发育及其有效成分积累动态含量,探讨了采收时期和生长年限对辽藁本产量和品质的影响。结果表明:3年生辽藁本在产量和活性成分方面均优于2年生辽藁本;比较营养生长期、孕穗期、盛花期、盛果期和枯萎期5个阶段的相关指标,在盛果期采收藁本,药材产量较高,质量好。 Taking Liao chinensis as test material, the growth and development and accumulation of active ingredients of two-year-old and three-year-old Liao chinensis at different growth stages were studied by means of drying weighing and high-pressure liquid chromatography. The effects of harvest time and Effect of Growth Years on Yield and Quality of Liao. The results showed that the yield and active ingredients of three-year-old Liao Habitat were better than those of the two-year Liao Habitat. The relative indexes of five stages of vegetative growth period, booting stage, full bloom stage, full fruit stage and wilting stage were compared. Transplant harvest period, high yield of medicinal herbs, good quality.
