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 discloses a method for promoting and controlling the cultivation of potted peonies for the Lunar New Year in Zhejiang Province, comprising the following steps: (1) Potting: Selecting peony division seedlings for potting from November 1st to November 5th; (2) Pretreatment: After potting, water thoroughly and place at room temperature for 7-15 days; (3) Low-temperature treatment: Place the pretreated plants, along with their pots, in a cold storage for low-temperature treatment for 35 days, during which no light, watering, or fertilization is required; (4) Greenhouse flower induction: After the low-temperature treatment, place the plants in a greenhouse and allow them to transition to room temperature for 2 days, then induce flowering for 47 days; (5) Hormone treatment: When the flower bud diameter reaches 10mm-15mm, apply gibberellin to the junction of the flower bud and the flower stalk; (6) Fertilizer and water management: In the greenhouse, perform routine daily management of the plants and continue greenhouse cultivation until flowering. This scheme achieves the regulation of pink Hawaiian peonies to bloom during the Spring Festival in Zhejiang Province.

This invention discloses the application of the MdNAC29 protein and its encoding gene in regulating plant flowering time, belonging to the field of biotechnology. This invention discovers a novel gene that regulates plant flowering time. MdNAC29 Genes, through overexpression within the plant MdNAC29 Genes can efficiently regulate the expression of genes in flowering-related pathways in plants, break the physiological blockage in the transition from vegetative growth to reproductive growth, significantly shorten the flowering induction time, effectively promote the early completion of the entire process of flower bud differentiation and flower organ formation, achieve early flowering, and significantly shorten the overall growth cycle.
