摘要
目的:研究外源钙施肥水平对甘草酸在甘草植物体内积累的影响。方法:对土壤盆栽2年生甘草、营养液培养2年生甘草和蛭石培养1年生甘草3种试验材料,采用3水平外源钙施肥处理,测定3种试验材料的甘草药材中甘草酸含量,进行方差分析。结果:在土壤盆栽2年生甘草中钙元素施入量为0.20kg/m2试验处理下,甘草酸相对含量显著高于对照和钙元素施入量为0.60kg/m2的试验处理,且单株甘草酸产量并未减少;在营养液培养2年生甘草和蛭石培养1年生甘草中浇入钙元素浓度为8mmol/L的试验处理下,甘草酸相对含量也显著高于对照和钙元素浓度为16mmol/L的试验处理。结论:适当浓度的外源钙肥的施入有利于甘草药材中甘草酸的积累,建议在人工种植甘草的生产实践中施入适量的钙肥以提高甘草药材质量。
Objective： Study on the influence of the exogenous ealcittm on the accumulation of glycyrrhizin in the cultivated Gtycyrrhiza uralensis Fiseh. Methods ： On the condition of the two annual Glyeyrrhiza uralensis cultured by common soil, two annual C.tycyrrhiza uralensis cultured by nutrition liquor,and one annual Glycyrrhiza uralensis cultured by vermieulaponics,by spraying different concentration exogenous calcium at three levels, the level of the glycyrrhizin in the three materials is mensurated to carry out variance analysis. Results： In the two annual Glycyrrhiza uralensis cultured by common soil, when the concentration of exogenous calcium is 0.20kg/m2, the relative amount of the glycyrrhizin is remarkably higher than the relative amount of the glycyrrhizin when the concentration of exogenous calcium is O. 60 kg/m2, and the control group. Besides, the simplex content of Glycyrrhizin doesnt grow downwards;In the two annual Glycyrrhiza uralensis cultured by nutrition liquor,and one annual Glycyrrhiza uralensis cultured by vermiculaponics, when the concentration of exogenous calcium is 8 mmol/L,the relative amount of the glycyrrhizin is significantly higher than the relative amount of the glycyrrhizin when the concentration of exogenous calcium is 16 mmol/L, and the control group. Conclusion： Appropriate concentration exogenous calcium helps the accumulation of glycyrrhizin ,it can increase the quality of the cultivated Glycyrrhiza uralensis Fisch.
