This invention discloses a cultivation method to improve the propagation efficiency of Rhodiola rosea, relating to the fields of plant cultivation and seed propagation technology. The cultivation method includes: (1) Seedling stage: after being treated with hormones, the seeds are sown in a light substrate and cultivated for 6-12 months to obtain strong seedlings; (2) Hydroponic transplanting and flowering induction stage: the strong seedlings are transplanted to a hydroponic system, and photoperiodic induction is performed using an artificial light source with a red-blue spectrum ratio of 1:1, combined with the phased adjustment of nutrient solution and the spraying of exogenous hormones to synergistically induce reproductive growth; (3) Pollination and seed collection stage: the seeds are collected after assisted pollination. This invention shortens the seed-to-seed cycle of Rhodiola rosea from the traditional 6 years or more to 2-3 years through multi-factor synergistic regulation, significantly improving the flowering rate and seed yield per plant, increasing the propagation efficiency by more than 99%, and is applicable to different ecotype seed sources, with the advantages of strong operability and good universality.

This invention provides a method and culture medium for directly inducing adventitious root production from Rhodiola rosea leaves, aiming to overcome the problems of low efficiency, long cycle, and limited resources in traditional Rhodiola rosea propagation methods. The method includes leaf selection and treatment, leaf-induced adventitious root production, and in vitro culture and acclimatization of the adventitious roots to improve their survival rate and growth quality. This invention establishes for the first time an adventitious root culture system for Rhodiola rosea plants. By optimizing the culture medium and environmental conditions, it achieves efficient induction and large-scale propagation of adventitious roots, which can be directly used for industrial production, increasing the accumulation of rhodiolosides, flavonoids, and various vitamins, ensuring component uniformity and efficacy stability. The culture method of this invention has the advantages of short cycle, high propagation rate, and strong controllability, effectively reducing dependence on wild resources and providing technical support for the sustainable development and biomedical application of Rhodiola rosea.

The application discloses a rhodiola crenulata pelleting seed and a preparation method and application thereof, relates to the technical field of rhodiola crenulata seed processing, and comprises the steps of seed pretreatment, preparation of a matrix, preparation of double-layer coated pellets, drying and low-temperature domestication. 3 The obtained rhodiola crenulata pelleting seed is nearly spherical, has a bulk density of 1.2-1.4 g / cm 3 , a compressive strength of 0.4-0.6 MPa, and can completely disintegrate in high-altitude soil with an altitude of greater than or equal to 2500 m within 7 days, and can be applied to high-altitude artificial large-scale planting, and solves the technical problems of small particle size, low germination rate, weak cold and drought resistance and great sowing difficulty of the rhodiola crenulata seed in the prior art.

This invention provides a method and culture medium for producing rhodioloside from adventitious roots of Rhodiola rosea via suspension culture. The method employs a segmented liquid suspension culture technique, comprising: establishing a sterile seedling system for Rhodiola rosea, obtaining sterile seedlings through specific sterilization and culture conditions; liquid culture and acclimatization of adventitious roots, shortening the growth cycle to 35-40 days and improving growth vigor by utilizing optimized culture media and acclimatization strategies; and optimizing the culture for efficient accumulation of rhodioloside, transferring adventitious roots to a specific induction medium and culturing them on a shaker for 8-10 days, ultimately achieving a rhodioloside content ≥0.6%. This invention eliminates the need for natural root collection, avoiding damage to wild Rhodiola rosea resources. It features a short production cycle, high efficiency, stable quality, and no heavy metal or pesticide residues, enabling large-scale industrial production to meet the demands of the pharmaceutical and health product markets. Simultaneously, it reduces reliance on wild resources, contributing to the sustainable development and utilization of endangered traditional Chinese medicine.
