【摘要】 目的:探讨施肥对栽培红芪不同生长时期红芪中多糖和总黄酮含量及产量的影响。方法:采用分光光度法测定不同生长时期红芪地上和地下部分多糖和总黄酮的含量。结果:施肥能够提高红芪地上部分多糖和地下部分总黄酮的含量,增加红芪地下部分在生长中后期的多糖积累。施肥处理组较不施肥处理组产量提高1 430 kg/hm2。结论:施肥能够提高红芪药材在收获期的质量和产量。更多还原

【Abstract】 Objective: To study the effects of fertilizer on polysaccharide content,flavonoids content and output of Radix Hedysari in different growth stage.Methods: The content of polysaccharide and flavonoids in different part of Radix Hedysari was examined in different growth stage by using spectrophotometric method.Results: Fertilizer could improve polysaccharide content of Radix Hedysari aerial part and total flavonoids content of root,increase polysaccharide accumulation amount of Radix Hedysari root in middle and late growth stage.The output of Radix Hedysari in the fertilizer group was 1430 kg/hm2 higher than that of no treatment group.Conclusion: Fertilizer can improve output and quality at harvest time in Radix Hedysari cultivation.更多还原
