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.

The present application relates to the technical field of plant growth and development regulation, and relates to a cultivation method for normal flowering and fruiting of winter (semi-winter) plants without low-temperature vernalization. The present application provides a cultivation method for normal flowering and fruiting of winter (semi-winter) plants without low-temperature vernalization, comprising the following steps: (1) sterilization and germination: after sterilization treatment, the plant seeds are germinated and cultivated in darkness to obtain plant seedlings; (2) vernalization-free cultivation: the plant seedlings are irradiated with the following light conditions in the vernalization-free cultivation, the light conditions comprise two or more of 400-500 nm, 600-700 nm and 720-750 nm, the light period adopts 16-22 h light / 2-8 h darkness, the light period temperature ranges from 20-28 DEG C, and the dark period temperature ranges from 18-26 DEG C. The present application actively replaces the sustained low temperature in the flowering induction process of winter plants by using light, a non-temperature environmental factor, thereby realizing exemption from the low-temperature vernalization stage.

The invention discloses a light source combination device and method for inducing sugarcane flowering, and relates to the technical field of sugarcane flowering induction, the device comprises a growth monitoring module, a light source regulation and control module, an environment monitoring module, a central control module and a mounting bracket; the growth monitoring module identifies the growth stage of the sugarcane, and the central control module is combined to control the light source regulation and control module to dynamically adjust the illumination intensity, so that the problem that the fixed illumination intensity is not matched with the requirements of different growth stages of the sugarcane is avoided, and accurate adaptation of the illumination intensity along with the growth of the sugarcane is realized; normal physiological activities of sugarcanes in various growth stages are guaranteed, flower bud differentiation efficiency is improved, the light source units are installed in a non-uniform distribution mode, illumination requirements of different parts of sugarcane plants are met, the problem of insufficient illumination utilization caused by uniform light source distribution of an existing device is solved, it is guaranteed that all the parts of the plants can obtain proper illumination, and the quality of the plants is improved. The flowering induction effect is further promoted.

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.

The invention provides a method for regulating and controlling flowering quality of floribunda camellia, and relates to the field of camellia planting. The regulation and control method comprises the following steps in the vegetative growth period of the camellia fragile: spraying a young shoot inducer to container seedlings of the camellia fragile in the vegetative growth period, and synchronously applying a growth-promoting nutrition supply agent; in the reproductive growth period of the camellias fragiena, the following operations are carried out: synchronously spraying a flowering inducer and a flower bud growth agent on the whole camellias fragiena container seedling in the reproductive growth period, and synchronously applying a nutrient supply agent for promoting the flower type on the camellias fragiena container seedling. Spraying a new shoot inducer, a flowering inducer and a flower bud growth agent until plant stems are wet and water drops drop from leaf tips. By means of the method for regulating and controlling the flowering quality of the floribunda camellia, the flowering quality of the container seedlings of the floribunda camellia can be effectively and remarkably improved, and the regulating and controlling purposes of improving the quality such as a large number of flower buds and the like are achieved.
