Detailed Guide to Seed Selection and Seed Treatment Methods for Licorice
Seed selection: Ural licorice (Glycyrrhiza uralensis), which has higher levels of glycyrrhizic acid and glycyrrhetinic acid, was chosen. Seed treatment: licorice seeds have a hard seed coat that is impermeable to water and air, making them difficult to germinate. Untreated seeds have a germination rate of only 30%-40%, while seeds treated by breaking the seed coat can reach a germination rate of over 90%, so the seeds must be pre-treated before sowing. The method used is: soak the seeds in water at 60°C, then remove them, cover them with a damp cloth for 4 hours to 6 hours to let them absorb water and swell, then air-dry and drain them before sowing.

What are the control methods for licorice rust disease?
① Pathogen The pathogen of licorice rust (Uromyces glycyrrhizae) belongs to Basidiomycota → Teliomycetes → Uredinales → Pucciniaceae → the genus Uromyces. ② Disease pattern a. Urediniospore stage In the seedling stage of licorice, infected plants show a light brown uredinium at the tip of leaves that have not yet unfolded. As the young leaves flatten and grow, the spore masses appear densely along the leaf tip and the underside of the leaf, and finally the entire underside of the leaf is covered by spore masses, appearing as a sheet of yellow rust color; generally all leaves of the whole plant become diseased, and diseased plants are noticeably dwarfed.

Symptom Identification and Control Methods of Licorice Rust
Latin scientific name: Uromyces glycyrrhizae Magn. Crops affected: Licorice. Symptoms: Mainly affects leaves. After seedlings emerge in spring, round, grayish-white small blister spots appear on the underside of leaves, and later the surface ruptures to reveal yellow-brown powdery masses, which are the pathogen's uredinia and urediniospores. In the late stage of the disease, the entire leaf is covered by uredinia, causing the aboveground part of the plant to die; the phloem tissue at the junction of the stem base with the root or stem proliferates, latent buds sprout, and the plant becomes clustered and dwarfed. After reinfection by urediniospores,

What does licorice look like? A detailed introduction to its morphological characteristics
Licorice is a perennial herb, reaching 30-80 cm in height, with rhizomes that mostly creep horizontally. The main root is very long and thick, with reddish-brown outer bark. The stems are upright, bearing short white hairs and bristle-like glands. The odd-pinnate compound leaves have 7-17 leaflets, ovate or broadly ovate, with acute or obtuse tips and rounded bases, bearing short hairs and glands on both surfaces. The papilionaceous corolla is pale purple. The pods are flat, sickle-shaped or curved into a ring, densely covered on the outside with bristle-like glands. The flowering period is June to July, and the fruiting period is July to September.

A Detailed Guide to Processing and Making Licorice Watermelon Seeds
Ingredients: 500 g watermelon seeds, 10 g peanut oil, 25 g refined salt, 3 g licorice, 50 g quicklime. Method: 1. Pour the quicklime into a large bowl, add 500 ml of clean water, stir well to make lime water, then add the watermelon seeds and soak for 4-5 hours, then remove them, rinse thoroughly with clean water, and remove the mucous membrane on the shells. 2. Put the refined salt and licorice into a pot, pour in 150 ml of clean water, place over high heat and boil for 10-15 minutes, filter out the licorice to make licorice salt brine

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.

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
