Embodiment 1

[0026] 1. Reasonable selection of land and treatment of planting materials

[0027] Collect wild Coptis chinensis in June, randomly select primary and secondary branches, cut into 5-10cm cuttings with terminal buds, and plant them at an altitude of 3500m. The vegetation around the planting site is dense, the slope is 10-20 degrees, and the soil For night tide soil.

[0028] 2. Field management

[0029] Combined with site preparation before planting, apply 3000kg of decomposed farmyard manure and 20kg of superphosphate per mu as base fertilizer, and then the width of the management box is 1.2m. When planting, the spacing between plants and rows is 10×40cm. Appropriate amount of mountain base soil, put a seedling every 10cm, cover with soil and suppress watering. The topdressing time is in late May every year, and 10kg of compound fertilizer (N:P:K=15:15:15) is applied to the roots; combined with fertilization and weeding and soil cultivation in May every year, 1-3cm of soil c...

Embodiment 2

[0030] In Example 2, Example 3, Example 4, and Example 5, except that the cultivation measures in Table 1 are different, all the others are the same as Example 1. See Table 2 for the survival rate, yield, and active ingredient content of Coptis chinensis.

[0031] Cultivation measures in table 1 embodiment 1-5

[0032]

[0033] Table 2 Comparison of survival rate and yield of Coptis chinensis after domestication and cultivation at different altitudes

[0034]

[0035] Note: 1. The yield after 3 years of planting refers to the yield of the rhizome of the medicinal part of Coptis chinensis after artificial domestication.

[0036] 2. The medicinal properties of Coptis chinensis. The contents of pidoside I and II are detected by high performance liquid chromatography. (conventional method) results and analysis:

[0037] Can draw from above-mentioned five embodiments:

[0038] 1. The method of the present invention can reduce the growth altitude to the mounta...

Abstract

The invention discloses a mountain rhizoma picrorrhiza introduction domestication method, which belongs to the technical field of traditional Chinese medicine cultivation. The technical points of the method comprise that the mountainous area with elevation of 2600 to 3500m is selected for planting, the row spacing of the plants is 10 to 30cm multiplied by 20 to 40cm, the shading rate in the first year is 50 to 70 percent, before planting, each Chinese acre field is applied with 2000 to 3000kg of well-rotted farmyard manure and 20 to 50kg of calcium superphosphate as base fertilizer; in late May every year, 10 to 40kg of compound fertilizer is applied in each Chinese acre field; in November, 1000 to 2000kg of well-rotted farmyard manure is applied in each Chinese acre field. The method reduces the growth elevation of the wild rhizoma picrorrhiza which is only suitable for growing in the area with harsh living environment and high elevation of 3900 to 4500m originally to the mountainous area with the elevation of 2600 to 3500m, the survival rate achieves above 80 percent, the protection and sustainable use of the endangered medicinal plant resources rhizoma picrorrhiza is realized, and medicinal material products can be provided for the market; and reference is provided for other mountain medicinal plant artificial domestication cultivation.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine cultivation, in particular to a method for the introduction and domestication of alpine berberine. Background technique [0002] Picrorhiza scrophulariiflora Pennell (Picrorhiza scrophulariiflora Pennell) is a perennial herb of the family Scrophulariaceae. It is a medicinal species officially included in the national pharmacopoeia, and it is also a national second-class protected plant. Huhuanglian is an important ethnic medicinal material that has been used by the Nu, Tibetan, Lisu, Naxi and other ethnic minorities for hundreds of years, and it is also an important raw material for various Chinese patent medicines. The distribution area of ​​wild Coptis chinensis is narrow, and its origin grows in the high altitude area of ​​3900-4500 meters. The living environment is harsh and its natural reproductive capacity is relatively weak. Due to long-term over-exploitation, wild res...
