Planting method for improving platycodon grandiflorum yield and medicine effect ingredient content

Abstract

The invention discloses a planting method for improving the platycodon grandiflorum yield and the medicine effect ingredient content, and belongs to the technical field of traditional Chinese medicinal material planting. According to the used method, DA-6 is sprayed for treatment; the combined treatment of the DA-6 spray application and the bud picking topping treatment is preferably selected. A method of combining DA-6 spray application and bud picking topping treatment is used, so that the single plant fresh weight and dry weight of platycodon grandiflorum can be improved by 50 percent or above; the diameter of platycodon grandiflorum roots can be increased by 45 percent or above; meanwhile, the lateral root number can be obviously reduced; the total platycodin content in the platycodongrandiflorum can also be increased by 56 percent or above; the platycodin-D content in the platycodon grandiflorum can be increased by 150 percent or above; the yield of the platycodon grandiflorum, particularly Zhongjiang platycodon grandiflorum, and the effective ingredient content in the medicinal material are obviously improved; the obvious economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of planting Chinese medicinal materials, in particular to a planting method for increasing the yield of platycodon grandiflorum and the content of medicinal components. Background technique [0002] Campanulaceae (Platycodon grandiflorum (Jacq.) A.DC.), also known as Doraki and Burdock Flower, is a perennial herbaceous plant belonging to the Campanulaceae family. Its root has important medicinal value. It can relieve lung and relieve throat, expel phlegm and discharge pus, eliminate dampness, regulate qi, promote qi and blood circulation, relieve fear and palpitation, and calm the mind; its flowers and buds are quite ornamental, and young leaves and roots are also It is a good vegetable, which can be described as a combination of medicine, food and reward. Modern pharmacological studies have pointed out that the main pharmacological active ingredients of platycodon are platycodon saponins, including platyco...

AI Technical Summary

Problems solved by technology

Zhongjiang, Sichuan is also the authentic production area of ​​platycodon grandiflorum, but the traditional method of planting platycodon grandiflorum is still maintained, which is easy to lose nutrients to the above-ground part, which is not conducive to the full development of individual underground parts, and the yield of platycodon grandiflorum is low

However, Zhongjiang Platycodon grandiflorum, which is an authentic medicinal material, has obvious differences in its growth environment and plant characteristics, and the effect of topping treatment on it is unknown.
