Detailed Explanation of Licorice Planting Methods and Technical Requirements
1. Selection of planting site. Under different climate and soil conditions, the yield and quality of licorice vary considerably. Licorice has strong adaptability to temperature conditions, while moisture conditions play a decisive role in licorice yield. According to the author's research, in regions of China's temperate zone with 300-500mm of precipitation, the rainfall in normal years can basically meet the growth needs of licorice, and it can be cultivated on land without irrigation conditions; however, to obtain high-quality transplant seedlings, the seedling nursery should have irrigation conditions. In areas with annual precipitation below 200mm, to obtain high quality and high yield, when there is no sufficient groundwater directly available for licorice use (groundwater level 2-3m), both the seedling nursery and the transplant site must have irrigation conditions.

Detailed explanation of key licorice cultivation techniques, master the essentials of growing it
1. Seed treatment Licorice seeds mature from July to August and should be harvested in time. The seeds are hard and their seed coats do not easily absorb water; when sown directly in soil, the germination rate is only about 30%. Before sowing, treat them with water at 60-100°C for 30 seconds; then soak them in warm water for 1 day and night, and the germination rate can reach 50%. If treated with concentrated sulfuric acid, remove them immediately and rinse them in clean water once the seed coat turns black, then soak them in warm water, and sow when the seeds swell; the germination rate can reach more than 90%. 2. Planting methods ① Direct sowing in the field The land preparation conditions are the same as for field crops, and sowing can be done in spring

Detailed Explanation of Key Points on Licorice Planting and Cultivation Techniques
1. Site selection and land preparation: For cultivating licorice, choose sandy loam soil with deep soil layers and a low groundwater table, and plowing to about 30 cm is sufficient. At present, flat cultivation is mostly practiced, and raised beds are rarely used; for good drainage and irrigation, the land can also be prepared into small beds and base fertilizer applied. Land preparation is best done by autumn plowing; spring plowing must preserve soil moisture, otherwise it will affect seedling emergence and seedling survival. 2. Propagation methods: In production, seed propagation is mainly used, and rhizome propagation can also be used. (1) Seed propagation: Before sowing, soak in 60°C warm water for several hours, mix crushed glass fragments with an equal amount of seeds and grind for half an hour, or soak the seeds in concentrated sulfuric acid (concentrated sulfuric acid:water = 1:1.5) for about 1 hour. Spring sowing is in March to April, and autumn sowing is in August to September. For drilling, open shallow furrows at a row spacing of 50 cm, with a furrow depth of 3 cm, evenly scatter the seeds into the furrows, and then cover with soil. For hole sowing, open holes at a hole spacing of 10-15 cm, sow 3-5 seeds per hole, and use 2-3 kg of seed per mu. After sowing, keep the soil moist; grass can be covered on the seedbed, and water should be given when the soil layer is dry. Seedlings emerge two to three weeks after sowing.

Pre-sowing treatment methods for licorice seeds
Treating Chinese medicinal herb seeds before sowing plays a major role in preventing and controlling pests and diseases, increasing the germination rate, and achieving uniform, complete, and vigorous seedlings. It is the primary prerequisite for stable and high yields, and can generally increase yields by 5%-20%. The treatment methods for licorice seeds are described below: licorice seeds have a thick and hard seed coat, making it difficult for the seeds to germinate. The seed coat can be broken by 3 methods: 1. Use a rice milling machine's high-speed rolling to make the seeds rub and collide with each other, damaging the seed coat (suitable for treating large quantities of seeds); 2. Mix the seeds with coarse sand and grind together for 5-10 minutes (suitable for treating small quantities of seeds

Control Methods for the Licorice Flea Beetle (Diorhabda tarsalis)
A leaf-eating pest of the Chrysomelidae family, it is one of the main obstacles to the development of licorice production. It is distributed to varying degrees in the ** Uyghur Autonomous Region, the Hexi region of Gansu Province, and the licorice-producing areas of Liaoning Province, mainly damaging sweet licorice (Glycyrrhiza glabra) and not harming other trees, shrubs, or other herbaceous plants. Throughout the entire growing season, adults are the main agents of damage and consume large amounts of foliage; adults and larvae often overlap in causing damage. In severely affected plots, entire stands of licorice are eaten down to only stems or leaf veins, and from a distance it looks as though the autumn withered and fallen-leaf period has arrived. Try
