A method for substantially increasing the content of Panax notoginseng total saponins

Abstract

The invention discloses a method for greatly increasing the total saponin content of Panax notoginseng. Annual Panax notoginseng with well-developed root system, no disease and no damage is selected as seedlings, and ethanol solution of methyl jasmonate, choline chloride aqueous solution or One or more infiltration treatments in naphthalene acetic acid solution, 10-15 days after transplanting, pour plant probiotics into the soil around the transplanted seedlings, and after transplanting for 1 year, spread them on the roots of the plants every 2 months Spray Genailing 20-30 times solution or anti-rhizobacillus agent 2-4 times solution around; after transplanting for 2 years, evenly spray salicylic acid solution and paclobutrazol aqueous solution to the leaves every other month, spray The amount is based on the moistness of the leaf surface and no dripping; 5 months before harvest, apply potassium fulvic acid. The method of the invention can promote the growth of the main root of the notoginseng, increase the weight of the main root, significantly increase the content of the total saponins of the notoginseng, reduce the incidence of root rot, improve the utilization rate of the fertilizer, and reduce the cost. The method of the invention is easy to grasp, has obvious benefits, and is suitable for popularization.

Description

technical field

[0001] The invention discloses a method for greatly increasing the content of total saponins of notoginseng, and belongs to the technical field of medicinal plant cultivation. Background technique
