Control methods for the Ningxia ground pearl (Porphyrophora ningxiana) pest on licorice
It is distributed in all licorice-producing areas nationwide, generally causing damage from the seedling stage to the mature plant stage. The Ningxia ground pearl has 8 host plant species, all of which are perennial leguminous herbaceous perennials, with licorice suffering the most severe damage, while other hosts are only slightly affected. (1) Damage period and damage symptoms: Overwintering nymphs can move intermittently when the surface soil temperature reaches 6°C, and become frequently active when the daily average temperature exceeds 12°C, in order to search for hosts. Early March is the initial activity stage, mid-to-late April is the peak period for searching hosts, and by mid-May they have basically all settled. From late May to late July

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

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

What are the methods for treating licorice seeds?
1. Sulfuric acid treatment method. For every 1 kg of clean seeds, use 20-30 ml of 80% sulfuric acid and stir evenly. Once uniform sulfuric acid etching marks are visible 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, the treatment time is shorter when the temperature is high and longer when the temperature is low. With more acid added, the treatment time is shorter; conversely, the treatment time is longer. 2. Seed coat crushing method. Place the seeds on a grinding pan at a thickness of 3 cm, turning them as you grind. When the seed coat is ground to a yellowish-white color

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
