Detailed Explanation of Key Points on Licorice Harvesting and Processing Technology
Harvesting and Processing Licorice is generally harvested after 1-4 years of cultivation. In Hebei and Beijing, it is harvested after 1-2 years of cultivation; in Inner Mongolia; Northeast China, and **, it is harvested after 3-4 years of cultivation. There are currently 2 cultivation methods: one is direct seeding, and the other is raising seedlings in the first year and transplanting in the second year. When transplanting, plant them flat and lay them horizontally in the field to facilitate harvesting. The first method is simpler and requires less labor; the second method is suitable for small-area household planting with intensive cultivation. For large-area planting, harvesting is a problem, and manual digging is very difficult. After many years of testing, a 55-type Iron Ox rubber-tired tractor can be used, with a plowing depth of about 45 cm, plowing one row at a time, and then manually using a four-tooth rake to pick out the licorice roots plowed out, then plowing the second row. One tractor paired with 10 workers can generally harvest about 10 mu per day, and the root damage rate is also somewhat lower than manual digging. The residual roots lost in the field are about below 10%, meeting the requirements, opening a new path for large-area licorice planting. After the harvested licorice roots are dried in the sun for a few days, use manual shears or a guillotine to cut off the rhizome heads and tails, and cut out licorice strips for cutting into oblique slices for export. The rhizome heads, fibrous roots, and tails are tied into bundles and used as hairy licorice for extracting licorice paste. For licorice grown for two years, the general dry weight of licorice strips is about 250-300 kg per mu, and hairy licorice is about 300 kg per mu. The output value per mu can reach about 4000 yuan.

Licorice should not be stored for too long; the storage time of medicinal materials must be reasonably controlled
Licorice is generally stored as compressed bales wrapped in burlap, each weighing 50 kg, kept in a dry, ventilated place, with a safe moisture content of 12%-14% for the commodity. There are more than ten kinds of warehouse pests of licorice, including the coffee bean weevil, the brown mulberry borer, and the four-spotted chestnut borer. Fumigation with nitrogen or carbon dioxide for 514 hours can kill all adults and larvae, with no obvious change in the inner quality of licorice. Licorice is prone to mildew. If the air humidity is too high, mold spots or white and green mycelium easily appear on the surface of licorice. The following measures can be taken for prevention and control

Licorice is not difficult to grow; master the method and you can grow it well.
At present, there is great demand for licorice products in domestic and international markets. Experts believe that to resolve the contradiction between the demand for licorice products and environmental protection, the most critical thing is to develop the artificial cultivation industry of licorice. From the current actual situation of artificial licorice cultivation, promoting the coordinated progress of planting and fenced breeding, and rationally developing the path of base construction, is practical and feasible. In fact, licorice is not a difficult plant to grow; as long as the soil and moisture are suitable, it can be planted on a large scale. Some people believe that the key to solving the problem of artificially cultivating licorice is now mainly not funding.

How to sow licorice? 5 steps to easily get planting done
Sowing licorice is a relatively simple method for this type of herb, but its key points should also be noted when cultivating it. The key points are as follows: 1. Sowing method. Site selection and land preparation. Licorice has wide adaptability and does not have strict requirements for the cultivation environment. It can be cultivated in semi-arid and arid areas with an average temperature of 4°C to 12°C and more than 2600 hours of sunshine, and it can also be planted on poor farmland returned from cultivation. However, it should also be noted that waterlogged low-lying areas, areas with a high groundwater table, and areas with heavy clay and acidic soil are not suitable for planting licorice.

Occurrence and Control Methods of Powdery Mildew in Licorice
The pathogen is a type of imperfect fungus among the fungi, with the scientific name Erisiphepolygoni. It damages the leaves, and diseased leaves develop white powdery growth on both the upper and lower surfaces. For control, spray 0.2-0.3 degrees Baume lime sulfur mixture.

Identification of Symptoms and Control Methods for Powdery Mildew on Licorice
It mainly damages leaves, and can also damage pods. The surface of affected leaves and pods is covered with a layer of white powder, and later many small black spots appear on the lesions, which can cause early defoliation or wilting of the whole plant. Control methods: spray 0.1-0.3 degrees Baume lime sulfur mixture, 50% thiophanate-methyl wettable powder 800 times dilution, 50% amobam 600 times dilution.

What plant is licorice?
A species in the genus Glycyrrhiza of the Fabaceae family, scientific name Glycyrrhiza uralensis Fisch., a perennial herbaceous plant. Also known as Guolao. Its rhizome and root are used as medicine, and it is a commonly used traditional Chinese medicine. It is mainly produced in China, the former Soviet Union, the Mediterranean coast and some countries in Central Asia. In China, it is mainly produced in the Northeast, Northwest and Inner Mongolia Autonomous Region. The product is exported in large quantities. It mainly relies on wild resources. Plants of the same genus include Glycyrrhiza glabra L. and Glycyrrhiza inflata Batal., which are also used as medicine, produced in Xin

What to do about bloody diarrhea in dogs? It can be treated with Pulsatilla decoction combined with Licorice and Donkey-Hide Gelatin
Bloody diarrhea in dogs is one of the most common canine diseases in clinical practice. The disease develops extremely rapidly, and treatment with antibiotics yields little or no effect, with a mostly poor prognosis. Pulsatilla decoction plus Licorice and Donkey-Hide Gelatin decoction is a representative formula in human clinical medicine for treating blood deficiency and prolonged diarrhea damaging yin, originating from the Jin Gui Yao Lue (Synopsis of the Golden Chamber). 1. Clinical symptoms: sudden onset, listlessness, fever, thirst with excessive drinking, little or no eating, dry nose, vomiting, diarrhea with pus and blood that is often bright red or purplish red, along with tenesmus, weakened or faint bowel sounds, a crimson tongue body, yellow coating, and a slippery or wiry rapid pulse

Detailed Explanation of Control Methods for Licorice Leaf Spot Disease
① The pathogen is a type of imperfect fungus (Cercospora astragali), belonging to the subdivision Deuteromycotina → Moniliales → Cercospora fungus. It damages leaves; affected leaves produce circular or irregular lesions, with the center of the lesion grayish-brown and the edges brown, and grayish-black mold-like growth on both the front and back of the lesions. Fruiting bodies grow on both sides of the leaf, but mainly on the upper surface; the stroma consists of only a few brown cells; conidiophores are born in bundles of 6 to 12, pale brown, with the apex lighter in color and narrower, unbranched, having 0 to 5 geniculate nodes, with the apex nearly truncate, spore scars prominent, and 1 to 7 septa; conidia are whip-shaped to obclavate, colorless and transparent, straight to curved, with the base truncate to nearly truncate, the apex slightly blunt, and 3 to 10 septa.
