Problems solved by technology

However, due to the particularity of the growing environment of Panax notoginseng and the singleness of the species, the barriers to continuous cropping of Panax notoginseng are very serious. The plots that have been planted with Panax notoginseng usually need to be rotated for 8-10 years before they can be planted again, so that the land area that can be cultivated with Panax notoginseng dwindling

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 [0002] Panax notoginseng is a perennial herbaceous plant belonging to Araliaceae ginseng. Its dried roots are used as medicine. It has two-way regulating functions of hemostasis and blood circulation. Saponin is the main medicinal ingredient and quality evaluation index of Panax notoginseng, which is a triterpenoid secondary metabolite based on the carbon frame structure. The 2015 edition of the "Pharmacopoeia of the People's Republic of China" stipulates that the medicinal material of Panax notoginseng is "Panax notoginseng of Araliaceae Panax notoginseng (Burk.) F.H. Chen The dried roots and rhizomes of this product also stipulate that "the total amount of ginsenoside Rg1 (C42H72O14), ginsenoside Rb1 (C54H92O23) and notoginsenoside R1 (C47H80O18) contained in t...
