Sowing and planting method for improving medicinal value of Gentiana scabra

Abstract

The invention belongs to the technical field of planting of Chinese medicinal materials, in particular to a sowing and planting method for improving the medicinal value of Gentiana scabra. The specific method is as follows: (1) in mid-March, immersing seeds of Gentiana scabra a nutrient solution of magnesium chloride, taking out the seeds from a filtrate, conducting electric field treatment, drying the seeds to have a moisture content of 24% to 26% for sowing; (2) treating planting land before sowing, applying decomposed folium-mori cattle manure, conducting shallow ploughing to have a depth of 18-20 cm, conducting bedding and building a shed; and (3) starting to spray a nutrient solution to leaf surfaces 24 to 28 days after seedling emergence, then spraying a nutrient solution to leaf surfaces once every 85 to 90 days until harvest is started; and from mid-May to mid-September every year, conducting 80% shading treatment from 8:00 to 17:00 every day, and conducting harvesting at the end of October of a second year. Therefore, the emergence rate reaches 98% or more, breeding of harmful bacteria is effectively inhibited, and harvest can be carried out in the second year, and the gentiana scabra gentiin content, erythricine content and gentiobiose / gentianose content are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese medicinal materials, in particular to a sowing and planting method for improving the medicinal value of gentian. Background technique [0002] Gentian is the rhizome of Gentiana, bitter in taste, cold in nature, and returns to the liver and gallbladder meridian. Ascaris, blood pressure lowering, diuretic, invigorating the stomach, stimulating the small intestine, relaxing skeletal muscles, clearing heat and dampness, purging liver and gallbladder excess fire, etc. It is mainly used to treat high blood pressure, dizziness, tinnitus, cholecystitis, acute infectious hepatitis, genital damp itching, damp heat jaundice , sores, furuncles, carbuncles, bitter mouth and convulsions, etc., are good medicines for protecting the liver and promoting gallbladder; It takes at least three years from sowing to harvesting of rhizomes, and the planting time is particularly long, and the content of gentios...

Problems solved by technology

[0002] Gentian is the rhizome of Gentiana, bitter in taste, cold in nature, and returns to the liver and gallbladder meridian. Ascaris, blood pressure lowering, diuretic, invigorating the stomach, stimulating the small intestine, relaxing skeletal muscles, clearing heat and dampness, purging liver and gallbladder excess fire, etc. It is mainly used to treat high blood pressure, dizziness, tinnitus, cholecystitis, acute infectious hepatitis, genital damp itching, damp heat jaundice , sores, furuncles, carbuncles, bitter mouth and convulsions, etc., are good medicines for protecting the liver and promoting gallbladder; It takes at least three years from sowing to harvesting of rhizomes, and the planting time is particularly long, and the content of gentioside, gentianine and gentisose in the gentian obtained after harvesting is not very ideal, resulting in unsatisfactory medicinal value, so A method that can effectively solve the defects of the existing technology should be invented
