摘　　要：目的:通过对安徽南陵栽培凤丹进行摘花蕾和砍老枝的技术处理,提高凤丹根皮的产量。方法:选择4年生凤丹实验田,划为3个实验区:摘花蕾实验区、砍老枝实验区和对照区,春季摘花蕾,于当年4～9月每月在摘花蕾区和对照区随机各挖取20株,记录根皮干重;秋季砍老枝,于翌年4～9月在砍老枝区和对照区每月随机各挖取20株,记录根皮干重;分别进行统计学处理和比较。结果:摘花蕾组与对照组产量增幅不大;但砍老枝组的凤丹产量明显高于对照组。结论:凤丹摘花蕾对凤丹皮的产量影响不明显,而适时砍去老枝能明显提高凤丹药材的产量。Objective：To increase the production of root bark of Fengdan by means of picking bud and cutting old branch cultivated in Nanling,Anhui province.Methods：An experimental plot where Fengdan has been culitivated for 4 years was selected,which was divided into 3 sections for the experiment of picking bud,cutting old branch and comparison.The buds were picked in spring of the first year.20 plants were dug randomly from both of picking bud and comparison section monthly during April and September,and the dry weight of their root bark was recorded,respectively.The old branches were cut in autumn.20 plants were dug randomly from both sections of cutting branch and comparison monthly during April and September of the second year,and their root bark dry weight was recorded.Results：The statistical and comparative results showed that compared to the comparison section,prcking bud section botains little increase of production of root bark,while cutting old branch section had got notable increase of production.Conclusion： Picking bud plays an unimportant role in the production of Fengdan bark,while cutting old branch has significant influence on it.
