What are the key techniques for high-benefit cultivation and management of licorice?
(1) Site selection and land preparation. Licorice has strong adaptability, and most soils can be used for planting except saline-alkali land. In autumn, apply barnyard manure or compost as base fertilizer, plow more than 20 cm deep, rake level and make beds 1 m wide and 17 cm high, and open small furrows on the bed surface for sowing at planting time. (2) Propagation methods. Use seed propagation and rhizome propagation. 1. Seed propagation. This method can be used to expand the area. (1) Seed treatment. Under natural conditions, the hard seed rate of licorice seeds is as high as more than 80%-90%. Pre-sowing seed treatment is the key to a high yield.

How to grow licorice for high yield? A full breakdown of the technical key points
1. Soil selection. Choose deep soil layers, good drainage, high-lying terrain, and sandy soil and sandy loam soil with relatively high calcium content. Waste flats and waste slopes with slightly alkaline soil and a pH between 7 and 8.5 can all be cultivated. Plots with low-lying terrain and heavy clay soil must not be planted. 2. Variety selection. Choose the new "Wosheng licorice" variety suitable for artificial cultivation. This variety has the following characteristics: First, strong adaptability, drought resistance, cold resistance, salt-alkali resistance, heat tolerance, and tolerance to poor soil. Its temperature adaptation range is 43 to 45°C. In areas with severe water shortage or relatively dry conditions, no wilting or death has been found, and it can adapt to weakly alkaline calcareous soil. At the same time, it is suitable for intercropping with young forest and fruit trees; second, a short growth cycle. With seedling raising and transplanting, the seedlings grow for 3 to 4 months, and after planting they can be harvested after 8 to 10 months of growth; third, fast growth. Because of its prostrate growth habit, combined with artificial cultivation techniques, it grows horizontally at 30 cm on the soil surface, and its absorption rate of natural conditions such as light, water, and fertilizer is high, so its growth speed is fast. Thirty days after sowing, 3 to 4 true leaves appear. At 60 days, the plant height is 30 cm, the root length can reach 20 cm, and the diameter is 0.5 cm; fourth, harvesting and processing are simple. All operations can be mechanized, less labor is used, and it can be sold after being naturally dried to 80 percent; fifth, high yield and good quality. The yield of medium rough grass per mu is more than 500 kg, and high-yielding fields can reach 800 kg. The skin is red, there are few branches, and the strips are uniform. It meets the standards of the national pharmacopoeia and complies with the germplasm requirements for building a GAP production base.

How to treat licorice seeds? A detailed guide to the warm water soaking method
Soak the seeds in warm water at 60°C, stirring constantly. Once the water temperature drops, remove the seeds and soak them in clean water until they swell, then remove and drain them before sowing. Warm water soaking can increase the germination rate of the seeds by 15%-20%. Alternatively, soak the seeds in warm water at 60°C for 4-6 hours, remove them and place them in a warm spot, cover with a damp cloth, and rinse with clean water twice a day, then sow once the seeds crack open.

Detailed Explanation of Sand Storage Treatment for Licorice Seeds
If a large quantity of seeds is used, sand storage treatment is mostly adopted. The method is: carry out the treatment about 2 months before sowing. First, soak the licorice seeds in 60°C warm water for 4~6 hours, stirring several times during soaking. After removing them, drain them, and mix them evenly with clean fine river sand at 5 times the volume of the seeds. The humidity of the river sand should be such that when squeezed in the hand, water appears but does not drip. Then put the evenly mixed seeds into a wooden box, pack the surrounding area tightly with wet sand that has not been mixed with seeds, and cover the top with a 3~5 cm thick layer of moist fine river sand. Finally, place the seed box into a prepared pit,

Detailed Guide to Licorice Cultivation: Planting Methods and Management Essentials
Licorice, also known as sweet grass or sweet root, has the effects of harmonizing medicinal properties, reducing or alleviating drug toxicity, and moistening the lungs. It also has the characteristics of cold resistance, heat tolerance, drought tolerance, sensitivity to waterlogging, and light preference, making it an excellent plant for windbreaks and sand fixation. Its cultivation techniques are as follows: For site selection and land preparation, sandy soil with deep soil layers, a deep groundwater table, and good drainage should be chosen. The soil salt content should preferably not exceed 0.2%. Areas with excessive rain or where the soil is relatively clayey and drainage is poor are not suitable for planting, because the roots tend to rot or the main root is short, with many lateral and fibrous roots, resulting in low economic value. The seedling nursery should preferably be chosen on relatively flat

Cultivation Timing and Management Key Points for Licorice
I. Seed Germination Habits (I) Water Absorption and Germination of Licorice Seeds Licorice seeds have a low emergence rate, generally around 10%, so they must be treated before sowing. Untreated seeds absorb water very slowly, and most seeds do not imbibe; seeds treated with concentrated sulfuric acid absorb water very rapidly, reaching over 100% within 4 hours. Generally, once water absorption exceeds 100%, the seeds have a very uniform germination capacity. If water absorption differs, the germination rate differs accordingly. At 20°C, after absorbing water for more than 1.5 hours, the germination rate reaches over 80%, at which point the moisture content is about 95
