Method for manually culturing rhodiola rosea in high-altitude area

Abstract

The invention discloses a method for manually culturing rhodiola rosea in a high-altitude area, belonging to the technical field of manual culturing of the rhodiola rosea. A seedling which is subjected to seed dressing with fine sands and sprout culturing with a low bed is taken as a germchit, the rhodiola rosea sapling which grows for 10-12 months in a sprout bed is transplanted into a land in the next March to May, a plant space and a row space of culturing in the land is 20-30cm, and muck is spread over the land after the seedling recovery; and in later each April to June, 1000-1500kg of muck is spread in each mu of land, water control processing is implemented in each August to September, the processing time is 10-30 days, a continuous period is 3-5 years, and the medicinal material of rhodiola rosea is harvested after finishing the process. According to the method, the seedling is subjected to the seed dressing with fine sands, so that seeds are enabled to be uniformly sown, and the quality of the sapling is improved; by adopting the muck to replace fertilizer, the quality of the medicinal material is guaranteed; and by the adoption of water control in a later period, the yield of the medicinal material is increased.

Description

technical field [0001] The invention belongs to the technical field of artificial cultivation of Rhodiola rosea, in particular to a method for artificially cultivating Rhodiola rosea in high altitude areas. Background technique [0002] Rhodiola crenulate (Hook.f.et THoms) H.Ohba is a herbaceous plant of the genus Rhodiola, also known as Rhodiola crenulate, belonging to the perennial succulent herb. The main axis rhizome on the ground is short, nearly cylindrical and horizontal, with a diameter of 0.6-3cm, a few remaining flowering branches, black, 5-20cm high, with sterile branches, erect, 5-17cm high, scale-like leaves densely attached to the apex, 1- 3cm, many flower stems, 5-20cm high, 1-9mm in diameter, erect or fan-shaped. Reddish when fresh. Basal leaves are underdeveloped, becoming scale-like, asymmetrical. Stems and leaves alternate, with short pseudostalk, elliptic oblong or round, 1-3mm long, 9-22mm wide, apex obtuse or shortly pointed, entire or wavy or crenat...

AI Technical Summary

Problems solved by technology

[0004] According to the available data, the artificial cultivation techniques for Rhodiola are mainly concentrated in the Alpine Rhodiola produced in Northeast China. The growth altitude is low, about 500-1500m. The sowing method is unscientific. Due to differences in geographical location and climatic conditions, high-bed seedlings are mostly used. These methods are not suitable for high-altitude areas such as Tibet and the Qinghai-Tibet Plateau.
