Embodiment 1

[0023] Test site: Licorice Base, Qiaotou Town, Wengniute Banner, Chifeng City, Inner Mongolia

[0024] Seed source: Seeds from Chifeng wild licorice base

[0025] Selected source of fertilizer: The manure is made of sheep manure as the main raw material, which has been exposed to the sun and decomposed, with a water content of 25%. Potassium sulfate is an excellent product of agricultural potassium sulfate produced by SDIC Xinjiang Lop Nur Potassium Salt Co., Ltd., K2O ≥52%, S≥17.5%; DAP fertilizer produced by Shifang Kanglong Chemical Co., Ltd., with total nutrients ≥74%, of which the ratio of N:P2O5:K2O is 21:53:0; North Huajin Chemical Industry Co., Ltd. Co., Ltd. produces urea with N≥46%.

[0026] High-efficiency compound foliar spraying agents: sodium chloride, sodium molybdate, boric acid, etc. are analytical reagents produced by Sinopharm Chemical Reagent Co., Ltd., chelated zinc, chelated manganese, and chelated calcium are produced by Langfang Matsumoto Technology Co...

Embodiment 2

[0034] The licorice fertilization method of this embodiment does not carry out inter-row cutting and vine treatment, only carries out furrow topdressing according to the conventional method, the depth of furrow application is 10cm, and no high-efficiency compound foliar spraying agent is carried out on the foliage. Others are the same as those in the embodiment. 1 same;

Embodiment 3

[0036] In the licorice fertilization method of this embodiment, inter-row vine cutting treatment is performed and soil topdressing is carried out at the same time, the depth of the furrow application is 15 cm, and the high-efficiency compound foliar spraying agent is not sprayed on the foliage. Others are the same as in Example 1.

Abstract

The invention relates to a fertilizing method for increasing glycyrrhizic acid content, which belongs to the technical field of traditional Chinese medicinal material cultivation, and comprises the following steps: (1) applying a base fertilizer in combination with deep ploughing and soil preparation before liquorice planting; (2) from May to the middle ten days of June of the second year and the third year of liquorice planting, when the seedling height ranges from 10 cm to 15 cm, a machine is used for cutting underground transverse stems of liquorice in the middle of two rows, the cutting depth ranges from 15 cm to 25 cm, and meanwhile topdressing is conducted through furrows; and from July to August, spraying an efficient composite leaf surface spraying agent containing a proper amount of NaCl, homobrassinolide and trace elements on leaf surfaces for three times. After three years of cultivation, the harvesting requirements of high-quality licorice medicinal materials with high glycyrrhizic acid content can be met. According to the fertilizing method, mechanical vine cutting, furrow application and topdressing and foliage application of the self-developed efficient compound foliage spraying agent are combined, physiological metabolism of licorice plants can be effectively regulated and controlled, the content of glycyrrhizic acid in the medicinal material reaches 2.5% or above, and the purposes of high quality and high yield are achieved.

Description

technical field [0001] The invention belongs to the technical field of cultivation of Chinese medicinal materials, and relates to a fertilization technology in the cultivation process of medicinal plants, in particular to a fertilization method for increasing the content of glycyrrhizic acid. Background technique [0002] Licorice (Glycyrrhiza uralensis Fisch.), a leguminous plant of the genus Glycyrrhizae (Glycyrrhiza uralensis Fisch.), is used as medicine with dried roots and rhizomes. Variety. Glycyrrhizic acid is the most important active ingredient in licorice. It has various pharmacological activities such as anti-inflammatory, anti-ulcer, anti-virus and immune regulation. It is clinically used in the prevention and treatment of chronic hepatitis, bronchitis, AIDS and various cancers. Glycyrrhizic acid is also a sweetener with high sweetness and low calorie value. When added to food, beverage, and candy, it can overcome the shortcomings of fermentation and rancidity c...
