Example Embodiment

[0038] Example 1

[0039] The test site of this example is located in the medicinal materials test base of Lameirong Village, Ludian Township, Yulong Naxi Autonomous County, Lijiang City, Yunnan Province, with an altitude of 2880 meters, an average temperature of 9.5°C, an absolute maximum temperature of 23°C, and an absolute minimum temperature of -14°C; annual rainfall 1043mm, the frost-free period is about 150 days, the relative humidity of the air is 87-89%; the soil is red-brown soil, the soil pH is 6.7, and the previous crop is kidney beans.

[0040] This embodiment consists of 4 steps including rational land selection, land preparation, seedling breeding and planting, and field management, and proceed as follows:

[0041] 1. Choose a place reasonably

[0042] Choose the above-mentioned cold mountainous area with an altitude of 2880m, the slope is 10-20 degrees, the soil is red brown loam with night tide habit, the relative air humidity is 87-89%, and the average content of ...

Example Embodiment

[0067] Example 2 and Example 3 are also examples of the high-yield cultivation method of P. chinensis according to the present invention. Except for the measures listed in Table 1, the other measures are the same as those in Example 1, and will not be repeated. The medicinal part of P. chinensis is the rhizome of P. chinensis The determination method and the determination unit of the sum (%) of the content of glycoside I and coprininoside II are the same as those in Example 1. See Table 2 for details.

[0068] Comparison 1 (patent applied) is the comparison of Example 3 with the highest output in the Chinese patent application number "200810058998.5" (the name of the invention is "a method for introduction and domestication of P. edulis") that the applicant has applied for. See Table 2 for the total output of P. chinensis and the content of P. chinensis in the rhizomes of the medicinal parts of P. chinensis.

[0069] Control 2 (Wild P. chinensis) is to collect wild P. chinensis as...

Abstract

The present invention pertaining to the field of traditional Chinese medicine cultivation technology relates to a high-yield cultivation method of picrorhiza. The method comprises processes of soil selection, soil preparation, seedling, breeding and management that are selecting a cold mountainous area with an altitude of 2700-3000m, brown soil having a night tide propensity, air with a relative humidity of 70-90%,soil with a organic content of 2-3%; fertilizing basic fertilizers with farmyard manure of 2000-3000kg and acid phosphate 20-50kg per mu yield; performing shading and earthing up processes to picrorhiza seedings adopting vegetative propagation; selecting axillary seedlings having fibrous roots and terminal buds to plant by a seedling space of 10-30cmX20-40cm, then coving the seedlings with black plastic films; maintaining a soil relative water content of 70-85% in the period of growth, and the like. According to the present invention, mu yield dry material of the medicinal positions can reach 260-300kg, thus, the output value is increased by 29-46% by comparation, comparing with the wild picrorhiza, the main active component content of the cultivated picrorhiza is increased by 1-3%, and the method has a strong integrity and is simple.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine cultivation, in particular to a high-yield cultivation method of Coptis chinensis. Background technique [0002] Picrorhiza scrophulariiflora Pennell (Picrorhiza scrophulariiflora Pennell) is a perennial herb of the family Scrophulariaceae. It is a traditional Chinese medicinal material officially included in the National Pharmacopoeia, and it is also a national second-class protected plant. Huhuanglian has the effects of clearing heat, dehumidification, improving eyesight, nourishing liver, benefiting gallbladder, and killing insects. Huhuanglian is also an important ethnic medicinal material and an important raw material of various Chinese patent medicines that have been used by the Nu, Tibetan, Lisu, Naxi and other ethnic minorities for hundreds of years. , infantile malnutrition, conjunctival congestion spontaneous sweating, night sweats, hemorrhoids, sores and swelling e...
