Embodiment 1

[0034] Adopt the following methods to carry out Rhodiola angustifolia seedling cultivation:

[0035] 1. Selection and arrangement of seedbeds: Choose plots with air-permeable and loose soil, rich in humus, flat terrain, and convenient drainage and irrigation, and remove weeds before the autumn frost of the year before sowing and after the soil thaws in the year of sowing.

[0036] 2. Seedbed soil preparation: plow the land deeply before the autumn frost one year before sowing, rake the land after thawing in the year of sowing, make ridges and ditches, the depth of the ditch is 0.3±0.05m, the distance between ridges is 0.4±0.05m, and the width of ridges is 1.9± 0.1m, then rake the furrows flat and wait for sowing.

[0037] 3. Seed selection and seed treatment: Use normal mature seeds, no mildew, no pests and diseases, and well-preserved seeds.

[0038] 4. Sowing: In the alpine region (the suitable growth area of ​​Rhodiola angustifolia), the sowing period is selected from late...

Abstract

The invention relates to a field seedling culture method for rhodiola kirilowii and belongs to the technical field of medicinal plant seedling culture and cultivation. The method is designed in order to solve the problems that due to the fact that alpine regions are large in ultraviolet radiation, evaporation capacity and temperature difference, seedling culture of rhodiola kirilowii seeds is difficult, so that artificial domestication cultivation of the rhodiola kirilowii is promoted, and sustainable use of medicinal materials is guaranteed. According to the field seedling culture method for the rhodiola kirilowii, after sowing is completed, a shading net with the shading rate ranging from 60% to 70% is adopted for coverage, and the coverage time ranges from 23 months to 26 months. The method is simple and high in operability, the rhodiola kirilowii seeds can adapt to extreme natural environment within a short time and effectively and rapidly grow, the problems that during traditional seedling culture, the seed seedling emergency rate is low, and grow is slow are avoided, the field seedling culture survival rate of rhodiola kirilowii is greatly increased, the seedling culture period is shortened, accumulation of rhodiola kirilowii underground biomass is effectively promoted, and seedlings can be transplanted in a short period on a large area.

Description

technical field [0001] The invention relates to a method for growing seedlings of Rhodiola angustifolia in the field, and belongs to the technical field of seedling raising and cultivation of medicinal plants. Background technique [0002] Rhodiola narrow leaves (scientific name: Rhodiola kirilowii (Regel) Maxim.), also known as Lion Seven, Dazhu Rhodiola, Lion Grass, Nine Lion Seven, Astringent Knot; Tibetan name transliteration: Gaduer, Suromabu, etc. , is a perennial succulent herb of the sedum family Sedum. Distributed in my country's Tibet, Yunnan, Sichuan, Xinjiang, Qinghai, Gansu, Shaanxi, Shanxi, Hebei and other places. It grows in the alpine region at an altitude of 2000-5600 meters (that is, the suitable growth area of ​​Rhodiola angustifolia). Rhodiola angustifolia has the functions of clearing away heat, reducing fever, detoxifying, and preventing blasts, and is suitable for pneumonia, fever, diarrhea, and swelling of limbs. Modern pharmacological studies have...
