Problems solved by technology

[0006] To sum up, the product of Swertia mitreya has definite curative effect, no toxic and side effects, a small range of suitable growth, and a large amount of medicinal materials. However, its wild resources are extremely scarce. At present, the annual production area can produce less than 1 ton of dry products, and it is facing depletion. Seeds are hard to find, there is no successful artificial large-scale planting, the germination rate of artificial planting in cultivated land is extremely low, the survival rate is low, and there are problems such as low plant biological yield, low content of active ingredients, and high mortality rate of plant injuries.

Embodiment 1

[0041] In May 2013, at Mile Xinshao, Honghe, Yunnan, around Alt.1450 m, 102 o 33 ， 47.49 ，， E, 24 o 50 ， 41 ，， N planted 50 square meters, the specimens were identified by Yang Yonghong's research group of Yunnan Agricultural University, and the seeds were identified and collected by Yang Yonghong's research group of Yunnan Agricultural University.

[0042] Swertia mitreya has not been artificially planted on a large scale so far, and it has been cultivated on a small scale with arable land, and the germination rate is extremely low. The present invention is:

[0043] 1. Site selection: positive hillsides or sunny limestone slopes in the hot and dry valley sandy land of Xinshao, 1100-1800m above sea level, soil pH=7.6-8.6, slightly alkaline, rich in macroelements available sulfur (30 -50 mg / kg), available potassium (greater than 250 mg / kg), iron (10-20 mg / kg) content graded in the high index range, trace elements zinc (2.0-4.0 mg / kg), copper (more than 2.0 mg / kg), moly...

Embodiment 2

[0051] In May 2014, at Honghe, Yunnan, opened the Yuanmazheshao, around Alt.1350 m, 102 o 33 ， 47.49 ，， E, 23 o 40 ， 41 ，， Plant 1 mu, and the seeds are harvested from the last planted field.

[0052] 1. Site selection: positive hillsides or sunny limestone slopes in the dry and hot sandy land of Xinshao, 1100-1800m above sea level, with sparse small shrubs and willows Dodonae viscosa clump or yellow grass Heteropogon contortus Grass, soil pH=7.6-8.6, slightly alkaline, critical indicators of soil nutrient abundance and deficiency are rich in available sulfur (30-50 mg / kg), available potassium (more than 250 mg / kg), iron (10-20 mg / kg ) content graded in the high index range, trace elements zinc (2.0-4.0 mg / kg), copper (greater than 2.0 mg / kg), molybdenum (greater than 0.2-0.3 mg / kg) graded in the high index range, the environment is loose soil, Good drainage, keep the seeds with a certain amount of water and permeability during germination, which is conducive to seed ...

Abstract

The invention relates to a wild Swertia mileensis ecological planting and nurturing method, and belongs to the technical field of Chinese medicinal crop wild introduction and domestication planting. The method includes: selecting full seeds of wild mature Swertia mileensis having the vigor greater than 50% to perform ecological planting and nurturing. The acquired mature seeds of the wild Swertia mileensis are processed, a planting land is selected, and then the germination rate and the survival rate of the wild Swertia mileensis seeds can be improved, the stress resistance of the wild Swertia mileensis plants can be improved, and the yield is increased. The advantages of the method are that the method is simple to operate, is stable and reliable in technique, is easy to promote, is fast in seedling emergence, is short in seedling cultivation cycle, is even in seedling emergence, is low in production cost, is high in quality and yield, is good in economic benefits, can produce mass Swertia mileensis seeds, and can promote artificial cultivation of the Swertia mileensis.

Description

technical field [0001] The invention belongs to the technical field of introduction, domestication, planting and plant propagation of wild Chinese medicinal materials, and in particular relates to a method for ecologically planting and raising wild Swertia maitreya. Background technique [0002] Maitreya Swertia is a plant of the genus Swertia in the family Gentianaceae Swertia mileensis The annual herbaceous plant of T.N.Ho et W.L.Shi is a unique plant in Yunnan. (Swertia genus is divided into 5 species of Indian Swertia, Japanese Dangyao, Dida, Swertia and Aoba). Medicinal dried whole herb, Yunnan Honghe Hani and Yi people have a long history of using it to treat hepatitis and other diseases. It was excavated from Mile and Kaiyuan in Honghe Hani and Yi Autonomous Prefecture of Yunnan in the 1970s; as a new medicinal Resources, included in the 1974 edition of "Drug Standards of Yunnan Province" and the 1977-2015 edition of "The Pharmacopoeia of the People's Republic of C...
