How to carry out field management of licorice? Four key points to master
Cultivation: Licorice seedlings grow slowly, and weeds have a relatively large impact on them. Cultivation should be combined with timely removal of weeds, with weeding 2-3 times in the same year. After the plants grow larger, weeds become fewer. Pay attention to pulling out weeds, and avoid hoeing the soil, so as not to damage new shoots sprouting from the rhizome. Topdressing: Licorice belongs to the legume family, and its root nodules have nitrogen-fixing ability, so nitrogen fertilizer is generally not applied, and phosphate fertilizer is mainly used for topdressing. After the aboveground parts of licorice wither in late autumn, 2000 kg of decomposed farmyard manure can be applied per mu to cover the ground, so as to increase ground temperature and soil fertility. Thinning: For direct-seeded seedlings of the same year, when they have 2-3 true

Detailed Explanation of Licorice Planting Technology and Market Analysis
I. Market Analysis Licorice is a perennial herbaceous plant of the Fabaceae family, with its roots and rhizomes used as medicine. Licorice is the king of traditional Chinese medicine and has a very wide range of uses. The underground part of licorice has effects such as clearing heat and detoxifying, moistening the lungs and stopping cough, quenching thirst and removing phlegm. Most traditional Chinese medicine prescriptions cannot do without licorice, commonly known as "nine out of ten prescriptions contain licorice." The above-ground part of licorice has high crude protein and crude fat content, and relatively low crude fiber content. The stems and leaves contain various trace elements needed by animals, and the feeding effect is similar to that of alfalfa (Medicago sativa), so it can serve as an excellent leguminous forage. In recent years, the price of licorice has been climbing

What kind of growing environment suits licorice?
The native range of licorice belongs to continental arid and semi-arid desert zones, characterized by drought, low rainfall, strong light and large temperature differences. Growing under these climatic conditions for a long time has given licorice its traits of cold resistance, heat tolerance, drought tolerance, fear of waterlogging and love of light, and it especially favors calcareous soil; it can grow in the arid regions of Northeast China, Northwest China and North China. The seeds exhibit hard-seediness, with a hard seed rate between 70% and 90%; alternating temperatures of -5 to 20°C give good germination, generally above 50%, and the seeds live for 1 to 2 years. Seed

What are the characteristics of the ecological environment in which licorice grows?
Licorice is widely distributed in the warm temperate and cold temperate continental monsoon climate zones of the arid and semi-arid regions of northern China. The suitable average annual growing temperature is between 3 and 10°C, and the altitude range is 250 to 1400 m. Licorice is an indicator plant of calcareous soils in the dry regions of China. Its requirements for soil are not very strict: it can grow in sandy loam, light loam, heavy loam and clay, and it grows best in sandy-covered loam with a sandy upper layer. Licorice has extremely strong cold resistance and drought tolerance; at an absolute minimum temperature of -47°C it still

Harvesting Methods and Technical Key Points for Licorice
For licorice grown from seedlings and transplanted, it is best to harvest at 2-3 years, with autumn harvesting giving the best quality. Before harvesting, the stems and leaves can first be cut off for use as livestock feed. Then harvest with a subsoiler or a special licorice harvesting plow, trying as much as possible to prevent damage to the root bark and premature root breakage. Shake the soil off the dug roots; they must not be washed with water. While still fresh, remove the remaining stems and fibrous roots, cut off the root heads, and grade them according to root thickness; the root strips must not be shorter than 20 cm. After trimming and cutting into sections, dry the licorice in the sun by grade. When sun-drying licorice, pay attention to protecting it from rain, and the drying yard must be free of contamination. When the licorice is half-dried, tie it into

Key Technical Points for Seed Treatment in Cultivated Licorice
Licorice seeds have a hard seed coat and poor water absorption, with a germination rate of only 4-6%. They need to be treated by milling or sulfuric acid to break the hard-seeded state and improve the germination rate and seedling emergence rate. I. Sulfuric acid treatment method. For each kilogram of clean seeds, use 20-30 milliliters of 80% sulfuric acid and stir evenly. Once uniform sulfuric acid etching marks appear on the seed coat, rinse with clean water and dry in the sun for later use. The treatment time depends on temperature and the amount of acid added. With the same amount of acid, a high temperature means a short treatment time, and a low temperature means a long treatment time. The more acid added,

Detailed Explanation of Key Techniques for Artificial Cultivation of Licorice
Licorice, also known as sweet grass, is a perennial herbaceous plant of the Fabaceae family. Its rhizome is used as medicine and has a wide range of applications. In recent years, medical workers in Japan and other countries have discovered that licorice has an inhibition rate of up to 98% against the AIDS virus and has strong immune function. The techniques for artificial cultivation of licorice are introduced below: 1. Cultivation methods. 1. Site selection and land preparation: Licorice mostly grows in dry calcareous soil. It prefers dry conditions and is cold-tolerant, so it is advisable to choose loose sandy soil with a low groundwater table and good drainage for planting. In this kind of land, the main root tends to extend downward, and the roots are straight and rich in powder. After the land is selected,

What are the varieties and types of licorice?
1. Licorice (Glycyrrhiza): The root is cylindrical, 30-120 cm long, 0.6-3 cm in diameter. The outer bark varies in tightness, red-brown, dark brown or grayish-brown, with obvious wrinkles and furrows, commonly known as "drawn furrows and sunken ridges," with sparse fine rootlet scars. The lenticels are transversely elongated, and the cut surfaces at both ends are slightly sunken in the center. The center of the cut section shrinks to about the size of a pepper eye, called "pepper eye." The texture is solid and heavy, the fractured surface is fibrous, yellow-white, starchy, with obvious cambium ring markings and radial striations, and fissures. The rhizome surface has bud scars

Processing Methods and Technical Key Points for Licorice Olive
The raw material used for licorice olive is also olive base, with the same processing technique as chili olive, only the formula is different, and of course the flavor is different too. The processing technique is as follows: 1. Raw material treatment: Desalt the olive base. Since the aim is to highlight the licorice flavor, too much salt should not be left during desalting; generally a slight saltiness is sufficient. After desalting, drain the water or bake until semi-dry for later use. 2. Licorice liquid preparation: Use 5% licorice liquid, that is, for 50 kg of olive base use 2.5 kg of licorice, add 50 kg of clean water, boil down into 20-25 kg of licorice liquid, filter and set aside.
