Detailed Explanation of Licorice Planting Methods and Technical Key Points
Licorice, also known as sweet grass root, sweet licorice, sweet root, powder grass, etc. It is a perennial herb of the genus Glycyrrhiza in the Fabaceae family, with its roots and rhizomes used as medicine. Sweet in taste, neutral in nature, it has the effects of clearing heat and detoxifying, moistening the lungs and transforming phlegm, tonifying the spleen and replenishing qi, relieving cough and resolving phlegm, and harmonizing various medicines. It is used for sores and ulcers, cough and sore throat, weak spleen and stomach, qi deficiency and lack of blood, common cold, stomach pain, limb pain, jaundice, periodontal disease and other conditions. I. Cultivation Techniques (I) Site Selection and Land Preparation Deep sandy soil or sand-covered land should be selected. Wind gaps should be avoided when selecting the site. After selecting the land, deep plow the soil 40

Six Methods to Improve Licorice Germination Rate
Licorice is a perennial herbaceous plant of the Fabaceae family, with its dried roots and rhizomes used as medicine. It has the effects of tonifying the spleen and replenishing qi, resolving phlegm and relieving cough, clearing heat and detoxifying, relieving urgency and stopping pain, harmonizing the properties of various medicines, and neutralizing the toxicity of a hundred medicines. Licorice is not only a major medicinal material, but also an excellent calorie-free sweetening additive in food, and an important auxiliary material for cigarettes and other industries, so the demand for licorice is growing ever larger. As natural licorice resources are increasingly depleted, artificial cultivation is necessary. Due to reasons such as the dense structure of the licorice seed coat and protein dehydration and denaturation, cultivating licorice suffers from problems such as slow germination, uneven germination, and low germination rate.

In the field of licorice research and development, our country has become the leader
It was recently learned at the founding conference of the Special Committee on Chinese Materia Medica Pharmaceutics of the World Federation of Chinese Medicine Societies and the International Symposium on Chinese Materia Medica Pharmaceutics that our country has successfully applied chiral catalysis technology to the purification of the active ingredients of licorice, increasing it from 3% to 97%, greatly saving medicinal materials. At the same time, following the recent introduction of the Class I new drug and chiral liver drug "Tianqing Ganmei", this shows that our country has already taken a world-leading position in the research, development and innovation of licorice preparations. Chiral technology works by scientifically adjusting the chemical structure arrangement

Occurrence and Control Methods of Root Rot in the Medicinal Plant Licorice
Symptoms The disease mainly affects the rhizome and roots. After infection, the stems and leaves of the aboveground part gradually turn yellow and wither, and the rhizome becomes yellow-brown to dark brown, sunken and rotten. The pathogen Fusarium sp. is a species of Fusarium, belonging to the Deuteromycotina fungi. For the morphological characteristics of the pathogen, transmission routes, disease conditions, and control methods, see Astragalus Root Rot.

Symptoms and Control Methods of Brown Spot Disease in the Medicinal Plant Licorice
Licorice, scientific name Glycyrrhiza uralensis Fisch., also known as meicao and micao, is a perennial herbaceous plant in the Fabaceae family. Its roots and rhizomes are used as medicine. It has the effects of harmonizing the middle and relieving urgency, moistening the lungs and detoxifying, and harmonizing various medicines. It is produced in Inner Mongolia, Gansu, Shanxi, Shaanxi, Liaoning, Jilin, Heilongjiang, Hebei and other provinces. The symptoms mainly damage the leaves. The lesions on the leaves are round or irregular, 1-3 mm in size, with a grayish-brown center and brown edges, and grayish-black mold-like substances, namely the pathogen's conidia, grow on both sides.

Adding rice husk to mushroom casing soil brings better planting benefits
In conventional mushroom cultivation management, casing soil is a technically demanding task. There are special requirements for the casing soil's texture, soil aggregate structure, aeration, and water retention and holding capacity. In particular, when making large, medium, and small casing soil particles, it is both labor- and time-consuming, and the labor intensity is high. To effectively solve these problems, the author has repeatedly reformed mushroom casing soil technology since 1990, and finally determined to use surface humus soil from within forest stands or paddy field plough layer soil (sandy loam or clay loam are both acceptable) mixed with 5% fresh rice husk

Rice cancer has met its nemesis: breeding of a disease-resistant new variety succeeds
Since the beginning of this century, rice stripe virus disease has continued to break out over large areas, in severe cases even causing rice farmers to lose their entire harvest. Rice stripe virus disease has been regarded as the "cancer" of rice. "Wuyujing 3", long recognized by the market as the main rice variety with the best taste and quality in Jiangsu Province and surrounding areas, has seen its planting area plummet in recent years because it is highly susceptible to rice stripe virus disease. Some stripe virus-resistant varieties either have shortcomings in yield and yield stability, or have not been fully recognized by the market for their rice quality. Rice farmers

How was the disease-resistant, fragrant and soft rice variety Jiuqi Xiang No. 1 bred?
I. Breeding process 1. Parent selection The internationally renowned rice variety Basmati, a superior rare fragrant-soft line obtained by mutation of Basmati original seed through solar radiation at this institute, and Xiangsimiao No. 2 were mixed and used as the male parent, with the conventional short-stalked, high-yielding, good-resistance and widely adaptable Qingzhen No. 8 as the female parent. 2. Progeny selection After a single plant was selected in the late season of 1991, various types of single panicles with medium-short stalks and plant-grain type similar to Xiangsimiao were selected respectively from the segregating materials of the F2 and F3 generations, then multi-generation selection and propagation and single-plant line comparative trials were carried out.
