摘　　要：结合十堰市茅苍术[Atractylodes lancea(Thunb.)DC.]种子种苗生产需求,以一年生茅苍术种子种苗为材料,开展不同叶面肥对种苗的生物量和干燥根茎苍术素含量的影响研究。结果表明,不同叶面肥均未能促进一年生茅苍术种苗植株增高,对须根长和须根数无显著影响,减少了地下根茎鲜重和干重,相对提高了干重占比,但显著提高了一年生茅苍术种苗根茎的苍术素含量。此外,尽管叶面肥采用尿素能够提高一年生茅苍术种苗的叶片生长,但叶面肥采用磷酸二氢钾和硝酸钾有利于提高一年生茅苍术种苗的苍术素积累,提高了品质,更有利于大田生产应用。Based on the production demand of Atractylodes lancea(Thunb.)DC.seeds and seedlings in Shiyan City,a study was conducted on the effects of different foliar fertilizers on the biomass and dry rhizome atractylodin content of one-year Atractylodes lancea(Thunb.)DC.seeds and seedlings.The results showed that different foliar fertilizers didn’t promote the growth of one-year Atractylodes lancea(Thunb.)DC.seedlings,and had no significant effect on the length and quantity of fibrous roots.They reduced the fresh and dry weight of underground rhizomes and relatively increased the proportion of dry weight,but significantly increased the content of atractylodin in the rhizomes of one-year Atractylodes lancea(Thunb.)DC.seedlings.In addition,although using urea as foliar fertilizer could improve the leaf growth of one-year Atractylodes lancea(Thunb.)DC.seedlings,using potassium dihydrogen phosphate and potassium nitrate as foliar fertilizer was beneficial for increasing the accumulation of atractylodin and improving the quality of one-year Atractylodes lancea(Thunb.)DC.seedlings,which was more conducive to field production and application.
