Example Embodiment

[0024] Example 1

[0025] The artificial cultivation of Rhodiola rosea on the Qinghai-Tibet Plateau includes the following steps: according to the mass ratio of fine sand: seed = 1000:1, with 1g / m 2 The standard for low-bed sowing and seedling, the seedlings grown in the seedbed for 10 months are moved into the field in March of the following year, the planting spacing is 20cm, the row spacing is 20cm, after the slow seedling, 1000kg of humus is applied per mu, and then 1000kg / mu in April each year. The standard spreading humus soil and implementing water control treatment in August each year keep the soil moisture content at about 40%. The treatment cycle is 10 days and can be harvested after 5 years. The dry weight of medicinal materials per mu is 240kg.

Example Embodiment

[0026] Example 2

[0027] The artificial cultivation of Rhodiola angustifolia in Tibet includes the following steps: according to the mass ratio of fine sand: seeds = 1000:1, with 1g / m 2 The standard for low-bed sowing and seedlings, the seedlings grown in the seedbed for 11 months are moved into the field in April of the following year, the plant spacing is 25cm, the row spacing is 25cm, after the slow seedling, 1200kg of humus is applied per mu, and then 1200kg / mu in May each year The standard spreading humus soil, and implementing water control treatment in September every year to keep the soil moisture content at about 50%, the treatment cycle is 20d, repeated 4 years can be harvested, the dry weight of medicinal materials per mu is 260kg.

Example Embodiment

[0028] Example 3

[0029] The artificial cultivation of Rhodiola, a holy land in Tibet, includes the following steps: according to the mass ratio of fine sand: seeds = 1000:1, with 1g / m 2 The standard for low-bed sowing and seedling cultivation, the seedlings grown in the seedbed for 12 months will be moved into the field in May of the following year, with a plant spacing of 30cm and a row spacing of 30cm. After slowing the seedlings, apply 1500kg of humus soil per mu, and then 1500kg / mu in June each year. The standard spreading humus soil, and implementing water control treatment in September each year to keep the soil moisture content at about 60%, the treatment cycle is 30d, repeat 3 years to harvest, the dry weight of medicinal materials per mu is 250kg.

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...
