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 substantially increasing content of total saponins of panax notoginseng. Annual panax notoginseng with developed root systems and without diseases and damage is selected as a seedling and infiltrated with one or more of an ethanol solution of methyl jasmonate, a choline chloride water solution or a naphthylacetic acid solution before transplantation, plant probiotics are poured into soil surrounding the transplanted seedling 10-15 days after transplantation, a 20-30-fold diluted solution of an agrobacterium tumefaciens treatment agent or a 2-4-fold dilutedsolution of an agrobacterium tumefaciens resistant microbial agent is sprayed to the surrounding of the root part of a plant every two months after the seedling is transplanted for 1 year; after the seedling is transplanted for 2 years, a salicylic acid solution and a paclobutrazol water solution are uniformly sprayed to leaf surfaces every month on the basis of the spray amount allowing the leafsurfaces to be wet without liquid drops dripping; potassium fulvic acid is applied 5 months before harvesting. By means of the method, growth of main roots of the panax notoginseng can be promoted, the weight of the main roots is increased, the content of the total saponins of the panax notoginseng can be notably increased, the morbidity of root rot is reduced, the utilization rate of fertilizer is increased, and the cost is reduced. The method is easy to master, has remarkable benefits and is applicable to 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...
