Effects of different foliar fertilizers on the growth and atractylodin content of Atractylodes lancea(Thunb.)DC.seedlings
Based on the production demand of Atractylodes lancea(Thunb.)DC.seeds and seedlings in Shiyan City,a study was con-ducted 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 Atracty-lodes 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 po-tassium 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.
