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.

How to process licorice kumquat? Detailed methods and steps
This product belongs to the preserved fruit category. The raw material used is salted kumquat base; fresh raw material is generally not used. The processing technique is as follows: 1. Desalting treatment: soak the salted base in water to remove salt, leaving about 2% salt in the base, that is, a slight salty taste is sufficient. 2. Semi-drying: sun-dry or bake. After draining off the water, it can be spread in a drying yard and sun-dried until semi-dry. If conditions permit, a drying room can be used for drying. It only needs to reach the semi-dry state, then set aside for use. 3. Preparing the liquid mixture: Preparation of licorice liquid: 50 kg of salted base requires 1.5-2.5 kg of licorice. If the licorice is of good quality, use 1.5 kg; if of poor quality, use 2.5 kg. Add 35-40 kg of clean water, heat and extract by boiling to draw out the licorice flavor, and continue heating and concentrating until about 12.5 kg remains, then filter to remove the residue. The licorice residue can be kept for continued use next time. Based on the raw material, weigh out 8% salt, 2-2.5% sodium cyclamate, and 1-1.5% food-grade citric acid, add them to the licorice liquid, dissolve them, and bring to a boil. Add the semi-dry raw material and stir so that it fully absorbs the liquid mixture. Generally, it should be left to stand for 8 hours.

Processing technology for licorice olives (also known as fruit-juice olives, chili olives)
(1) Process flow: material selection → skin rubbing → brine curing → soaking → drying in the sun or oven → absorbing flavorings → drying in the sun or oven → finished product. (2) Key operating points: Select moderately ripe green olives (not yet fibrous). First rub off the skin, then add salt to cure the blank. For those requiring longer-term preservation, add more salt. Both wet blanks and dry blanks can be preserved. Before making, first soak in water to remove salt: licorice olives should retain more saltiness, while fruit-juice olives should be soaked until lightly salted. After soaking, they must still be dried in the sun or oven until 80% dry, so as to absorb the flavorings. The production method for all kinds of olives is the same; the difference lies in the blending of flavorings. Licorice olives are based mainly on licorice,

Detailed Explanation of the Key Processing Techniques for Licorice Bitter Melon
Remove both ends and the seeds from the bitter melon, split it into two halves, cut it into strips about 4 cm long, blanch them in a pot of boiling water, then soak them in a vat of cold water and take them out the next day to drain. Put them in a vat and add salt, one layer of melon and one layer of salt. After 1 to 2 days, transfer the whole batch, together with the brine, to another vat once, and after another 1 to 2 days, take them out and sun-dry them until fully dry to make dried bitter melon blanks for later use. Pour boiling water equal in weight to the original fresh melon into a vat, then add auxiliary ingredients such as perilla powder and licorice powder and mix well, so that the dried bitter melon is evenly moistened, then take it out and sun-dry until 80 percent dry.

Licorice Pest Control Methods and Technical Key Points
(1) Leafhoppers: mainly the elm leafhopper, the small green leafhopper, etc. They occur throughout the entire growing period of licorice, with the most severe damage from late June to mid-August. Nymphs or adults suck the sap of licorice leaves, buds, young branches and young shoots, first showing silvery-white dot-like spots, then the leaves lose chlorophyll and turn pale yellow, and finally fall off. Control methods: Clear the elm trees and other overwintering hosts of leafhoppers around the licorice field. At the peak of infestation, spray with 2.5% deltamethrin at 1000-1500 times dilution. Use natural enemies such as cotton aphid parasites and ladybugs
