Embodiment 1

[0012] Embodiment 1: A kind of introduction and cultivation technology of Swertia japonica plants, comprising the following process steps: 1. The wild or cultivated Swertia japonica plant seeds are placed in a temperature of -10-10°C for 10-150 days in a refrigerator, which can be used The seed germination rate reaches more than 80%; 2. in spring (3-6 months in the plateau area) or autumn (8-9 months in the plateau area), the treated Swertia plant seeds are directly sown in the For large irrigated fields or suitable dry land at an altitude of 1500-4500 meters, the sowing rate is 2.25-60 kg / ha, and the sowing depth is 0.1-2.0 cm. Using broken rice, wheat straw or other shading means can increase the emergence rate of the field.

Embodiment 2

[0013] Embodiment 2: A kind of introduction and cultivation technology of Swertia plant, comprising the following process steps: 1. The wild or cultivated Swertia plant seeds dried in the shade are stored in a plateau at room temperature of -5-20°C, and the concentration of 10 The gibberellin soaking treatment of -800mg / L for 1-48 hours can make the germination rate of seeds reach more than 80%; The treated Swertia plant seeds are directly sown in a water-irrigated field or suitable dry land at an altitude of 1500-4500 meters by sowing or drilling, with a sowing rate of 2.25-60 kg / ha and a sowing depth of 0.1-2.0 cm. Using broken rice, wheat straw or other shading means can increase the emergence rate of the field.

Embodiment 3

[0014] Embodiment 3: a kind of introduction and cultivation technique of Swertia japonica plants, comprising the following process steps: 1. The wild or cultivated Swertia japonica plant seeds which are dried in the shade are overwintered and placed for 15-150 days at the natural temperature (-20-10° C.) in the north , can make the germination rate of seeds reach more than 75%; 2. in spring (3-6 months in the plateau area) or autumn (8-9 months in the plateau area), the treated Swertia plant seeds will be sown or drilled Sow directly in the irrigated field or suitable dry land at an altitude of 1500-4500 meters, the sowing rate is 2.25-60 kg / ha, and the sowing depth is 0.1-2.0 cm. Using broken rice, wheat straw or other shading means can increase the emergence rate of the field.

Abstract

A technique for planting swertia features that the seeds of swertia are physically and chemically treated for high germination rate up to more than 75%, and the ground is covered by plastic film for 7-28 days before said seeds are sowed for suppressing the growth of weeds. As a result, the swertia can be cultivated in the highland with 1500-4500 m above sea level.

Description

technical field [0001] The invention relates to a technique for introducing and cultivating plateau plants, in particular to a technique for introducing and cultivating swertia plants. Background technique [0002] The Qinghai-Tibet Plateau is a unique natural geographical unit in my country. Its unique natural environmental conditions breed rich and unique Chinese and Tibetan medicinal resources, which have pure natural characteristics. Plateau plants have long adapted to the special natural environmental conditions of the plateau area, forming many plateaus. It has unique physiological-ecological characteristics, and has unique medicinal properties and efficacy. Tibetan medicine is an important part of the treasure house of Chinese medicine. It has a unique theoretical system and distinctive national characteristics. It is a summary of the valuable experience of the Tibetan people in fighting diseases during their long-term survival and development. In recent years, the de...
