Overwintering seedling growing method for using rhodiola rosea rhizome as germchit

Abstract

The invention discloses an overwintering seedling growing method for using rhodiola rosea rhizome as germchit. The method comprises the steps of building cultivation rectangular pieces of land in a field, preparing nutrient soil, digging planting furrows on the rectangular pieces of the land in the field, selecting good-quality rhodiola rosea rhizome, cutting the rhodiola rosea rhizome into seed tubers, disinfecting the seed tubers through Chinese medicine liquor, then soaking the tubers to promote rooting and sprouting of the rhodiola rosea rhizome, laying the nutrient soil in the planting furrows, planting the rhodiola rosea rhizome seed tubers at a fixed interval, then covering the rhodiola rosea rhizome seed tubers with the nutrient soil and a mixture, and then putting up an arched shed over the rectangular pieces of the land in the field. According to the overwintering seedling growing method for using the rhodiola rosea rhizome as the germchit, the seedling growing method is simple and is easy to operate and achieve, the seed tubers which are disinfected and soaked are not prone to rotting in the soil of the rectangular pieces of the land in the field, the water content meets the demand of the seed tubers for taking root, the seed tubers can take root within 5-7 days, the sprouting and emergency rate of the seed tubers reaches 96%, each rhodiola rosea rhizome seed tuber has 3-4 shoot apices, the seedlings come out evenly, and a solid foundation is laid for later transplanting of the seedlings to cultivate strong seedlings and strengthening stress resistance in the seedling stage.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method for raising seedlings overwintering by using rhodiola rosea rhizomes as seedlings. Background technique [0002] Rhodiola is aliased as Rhodiola rosea, Saulomabul (Tibetan name), etc.; it is a perennial herb with a height of 10-20 cm. The root is thick, conical, fleshy, brownish yellow, with many fibrous roots at the root neck, the rhizome is short, thick, cylindrical, covered by many scale-like leaves arranged in tiles. It grows in the alpine and pollution-free zone at an altitude of 1800-2500 meters, and its growth environment is harsh, so it has strong vitality and special adaptability. It can be used as medicine, can invigorate qi and clear the lungs, improve intelligence and nourish the heart, and is a traditional Chinese medicine with a wide range of effects. It also has a great cosmetic effect and can be used as a skin care product or edible. [0003] Due to o...

Problems solved by technology

If the problem of resource supply is not effectively resolved, the fragile native ecosystem of Rhodiola itself will be difficult to maintain and protect, which will inevitably lead to the reduction of biological resources of Rhodiola plants and the loss of genetic diversity resources, which in turn will lead to Destruction of native ecosystems on which nature depends
