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.

Detailed Explanation of Licorice Planting, Cultivation Techniques and Management Key Points
Overview Licorice, also known as sweet grass root, red licorice, and powdered grass. It is the leguminous plant licorice Glycyrrhiza uralensis Fisch., with the root and rhizome used as medicine. It has the effects of clearing heat and detoxifying, moistening the lungs and stopping cough, and harmonizing various medicines; processed licorice has the effect of tonifying the spleen and boosting qi. Plant characteristics: perennial herb, root thick and robust, cylindrical, sweet-tasting, outer bark brownish-red. Stem erect, slightly lignified in the lower part. Leaves alternate; odd-pinnate compound leaves, leaflets 7-17, ovate-elliptic, both surfaces covered with glands and short hairs. Racemose flowers

Detailed Explanation of Key Techniques for Licorice Seed Treatment
Licorice seeds begin to germinate at 10-15°C, and germinate fastest at 15-20°C. The germination rate of old seeds decreases. One of the greatest characteristics of licorice is that it exhibits hard seediness, with the hard seed rate usually between 70-90%, making it very difficult for seedlings to emerge after sowing. Therefore, when propagating by seed in production, treatment before sowing is essential. The general treatment methods include the following: (1) soaking seeds in boiling water; (2) soaking seeds in concentrated sulfuric acid; (3) grinding with crushed glass; (4) milling with a rice mill. Among these, milling with a rice mill gives the best results. Generally, a few days before sowing, use a rice mill to mill the seeds 1-2 times.

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

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

How to Treat Licorice Seeds? A Detailed Guide to the Correct Method
The methods currently used in production are as follows: (1) Sand abrasion method: mix licorice seeds with clean river sand at a 1 to 1 ratio, put them into a container, and stir repeatedly so that they rub against each other; sow once the seed coat is no longer shiny. This method is labor-intensive and is only suitable for treating a small quantity of seeds. (2) Rice milling machine treatment: grind the licorice seeds with an electric rice milling machine for 2-3 passes, until the seed coat is scratched but the kernel is not broken. (3) Warming and repeated soaking method: soak the seeds in 60°C warm water for 6-8 hours, and use the "rice-washing method" to float off the seeds in the upper layer that have already absorbed water; then take the

Harm and Control Methods of the Licorice Seed Chalcid
Adults lay eggs on the seed coat of green fruits; after the larvae hatch, they immediately bore into and feed on the seeds, and pupate inside the seeds. After the adults emerge, they bite through the seed coat and escape. The infested seeds are eaten out into empty shells, and small round emergence holes are left on the seed coat and pods. This pest has a great impact on yield. Control methods: ① In winter, clear away residual leaves to reduce the source of the pest. ② Before sowing, the seeds must be treated, either by removing the insects or by dressing the seeds with carbaryl powder. ③ During the occurrence period, especially the green fruit stage, spray with pesticide.

Direct seeding cultivation techniques for licorice in the Hexi arid region
Licorice is the most commonly used bulk medicinal herb, hailed as the king of medicines. The currently cultivated species is Glycyrrhiza uralensis (Ural licorice), a plant of the genus Glycyrrhiza in the Fabaceae family. It is highly water-saving, drought-tolerant and cold-tolerant, and is an excellent windbreak and sand-fixing vegetation for arid and semi-arid desert areas. The medicinal part is the dried root, which not only has effects such as tonifying the spleen and boosting qi, relieving cough and expelling phlegm, clearing heat and detoxifying, and harmonizing the properties of medicines, but is also widely used in daily necessities, light industry, animal husbandry and the food industry.
