Detailed Explanation of Licorice Cultivation and Grassland Reseeding Techniques
Licorice (Glycyrrhiza) is a wild medicinal and forage plant. Based on its biological and ecological characteristics, adopting agricultural technical measures can break seed dormancy and increase the germination rate; meet the water and nutrient requirements of licorice growth and development, and increase its biomass yield. 1. Licorice cultivation techniques (1) Seed treatment. Use a rice mill to scratch the seed coat, taking care not to crush the seeds; milling twice gives the best results, and the germination rate can be increased from 30% to over 80%. (2) Site selection and pre-sowing land preparation. On sandy land, sand-covered land, and beach land types

Detailed Explanation of Key Licorice Cultivation and Management Techniques
Licorice, also known as sweet grass root, red licorice, and powder grass, is a leguminous plant, with its root and rhizome used as medicine. Licorice is a perennial herbaceous plant, 30-40 cm tall. The root is thick and sturdy, cylindrical, with a sweet taste, and the outer bark is brownish-red. The stem is upright, slightly woody at the lower part. The leaves are alternate, and the flowers are papilionaceous, light purplish-red. The seeds are flat and round. The flowering period is June-July, and the fruiting period is July-September. Licorice is sweet in flavor and neutral in nature, with effects of clearing heat and detoxifying, moistening the lungs and stopping cough, and harmonizing various medicines, and is regarded as the elder of all medicines. Except for waterlogged lowlands and land with a high groundwater table, which are not suitable for planting, other

What are the cultivation methods for licorice? Detailed explanation of the key planting techniques
There are mainly two. (1) Direct seeding, generally done in rows, with a row spacing of 30-50 cm, a furrow depth of 3-4 cm, and 2 cm of covering soil, with a seeding rate of 2-3 kg per mu. Because direct-seeded products develop many branched roots, with the roots thick at the top and thin at the bottom, most fail to meet the quality standard, and because digging them out is laborious and highly labor-intensive, in production generally only seed-production fields use this method. (2) Seedling raising and transplanting, which is mostly used in production because of its high yield, excellent quality, low labor intensity, and high economic benefit. Generally, raising one mu of seedlings requires seeds

How to Select and Prepare Land for Planting Licorice
Usually, sandy soil that is fertile, loose in texture, well-drained and low in salinity and alkalinity is chosen for planting licorice, and it requires a deep soil layer and a low groundwater table. In North China, Northeast China and Northwest China, licorice should be cultivated on sand dune areas or on high-lying alluvial soil on both banks of rivers; this kind of licorice is rich in powder, low in fiber and strong in sweet taste; saline-alkali land should not be chosen, otherwise the cultivated licorice will have short main roots and many branches, with rhizomes growing horizontally on the surface, thin and weak, and the product will be light in weight, low in powder and not strong in sweet taste. Choose sandy loam with a deep soil layer; as long as it is plowed about 30 cm

What to do about pigeon dysentery? It can be treated with the Chinese herb licorice
When a pigeon suffers from dysentery, its droppings are as thin as water, green with a yellow tinge. The sick pigeon huddles in the coop, drinking large amounts of water but not eating, and its condition worsens by the day. Buy licorice, mash it up and administer it to the sick pigeon by mouth, and also soak licorice in water for the sick pigeon to drink. The next day the droppings had already changed from thin to dry. Continue treating with licorice, and in less than a week the sick pigeon can recover. According to "Compendium of Materia Medica" by Li Shizhen, "Licorice, sweet and neutral in nature and flavor, mainly treats cold and heat pathogenic qi of the five zang and six fu organs, and resolves a hundred toxins," and "treats red and white dysentery, and taken it works immediately."

Detailed Explanation of Key Points for Artificial Cultivation Techniques of Chinese Licorice
Licorice, also known as sweet root and dense grass, has 23 varieties worldwide. China is the country with the most licorice distribution, with 12 varieties. Ural licorice (i.e., Chinese licorice) is the most widely distributed, highest-yielding and best-quality licorice species among the six licorice species listed in the pharmacopoeia of China, and has long enjoyed a high reputation in the international market. Licorice is a perennial herbaceous plant of the Fabaceae family, and its roots and rhizomes have the effects in traditional Chinese medicine of harmonizing various medicines and neutralizing a hundred toxins. China has the sayings "nine out of ten prescriptions contain licorice" and "no prescription is complete without licorice," so it is called the king of Chinese herbal medicines. Licorice

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.

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.

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

Intercropping Cultivation Techniques for Licorice in Land Returned from Farmland to Forest
Intercropping licorice in land returned from farmland to forest can both conserve soil and water and increase economic returns, achieving the goal of using the land to support the forest and the forest to support the land, and realizing a "win-win" for both the economy and ecology. Since 2002, Regiment 137 has conducted cultivation trials of intercropping licorice in land returned from farmland. After several years of experimentation and exploration, breakthrough progress has been made. 1. Land selection: Select sandy loam plots of land returned from farmland to forest with relatively low salinity and alkalinity, relatively few field weeds, and good drainage for intercropping licorice. The main tree species planted in the sowing area is wolfberry seedlings; the planting pattern is furrow planting
