施用不同中药渣对甘草生长及有效成分含量的影响

中药产业产生了大量的中药渣,目前中药废渣多数被当作生活垃圾处理,造成环境的污染和资源的浪费。针对上述情况,该文采用研究了不同中药渣对甘草生长及有效成分含量的影响,结果表明施用白术药渣能显著提高甘草地上部分生物量、叶片数、分枝数和地下部分的根粗、根重,增加幅度达到0.53~1.81倍。施用连翘药渣效果次之,其中甘草地上部分生物量、分枝数和地下部分根粗、根重较对照增加幅度为0.43~1.13倍。而且,施用白术药渣还能显著提高甘草根部甘草酸的含量,同对照相比,提高幅度为1.54倍。白术渣、苦参渣、连翘药渣、麦芽渣4种中药渣均能显著提高甘草地上部分生物量,提高幅度为0.43~1.81倍。综合而言,作者推荐在甘草种植生产施用适量白术药渣和连翘药渣,以有效提高药材品质和产量。

Effect of herb residue on growth and active ingredient content of licorice

Traditional Chinese medicine industry product a lot of herb residue. Herb residue was treated as household waste. This treatment leads to environmental pollution and resource waste. For this case, we study the effect of different herb residues on the growth and active ingredient content of Licorice by random control experiment. Our results showed that the effects of different herb residues were difference. Atractylodes macrocephala residue and Forsythia suspense residue had the stronger effect and the effect of A. macrocephala residue was inferior to the effect of F. suspense residue. A.macrocephala residue significantly improved the shoot biomass banch number, leaf number, root diameter and root biomass by 0.53-1.81 fold. A. macrocephala residue also increased the glycyrrhizic acid content of root by 1.54 fold. F. suspense residue significantly improved the shoot biomass,branch number, root diameter and root biomass by 0.43-1.13 fold. Four kind herb residues all improved the shoot biomass by 0.43-1.81fold. So, the authors recommand to considered that we can apply A. macrocephala residue and F. suspense residue in Licorice cultivation.
