How to deal with licorice seeds?
At present, there are the following methods used in production: (1) sand grinding method: the licorice seeds and clean river sand are mixed at a ratio of 1 to 1, put into a container, stirred repeatedly to make them rub, and can be sown when the seed coat is not bright. This method is labor-consuming and is only suitable for the treatment of a small number of seeds. (2) Rice milling machine treatment: licorice seeds were milled with electric rice grinder for 3 times in order to cut the seed coat and keep the seed unbroken. (3) heating and re-soaking method: soak the seeds in 60 ℃ warm water for 6-8 hours, bleach out the seeds that have been soaked in the upper layer by the "rice washing method", and then rinse the seeds in the lower layer.

Skillful treatment of licorice seeds
The treatment of the seeds of traditional Chinese medicine before sowing can prevent and control diseases and insect pests, improve the germination rate, and play an important role in Miaoqi, Miaoquan, and Miaozhuang. it is the primary prerequisite for stable and high yield, and generally the yield can be increased by 5% and 20%. In this paper, the treatment methods of licorice seeds are introduced as follows: licorice seeds are thick and hard, and the seeds are not easy to germinate and can destroy the epidermis. There are three methods: ① uses the high-speed rolling of the rice mill to make the seeds rub and collide with each other and injure the epidermis (suitable for a large number of seeds); ② grinds seeds and coarse sand together for 5 minutes (suitable for a small number of seeds)

Treatment methods of licorice seeds
1. Sulfuric acid treatment. Stir the pure seeds with 20-30 milliliters of 80% sulfuric acid per kilogram. See that the seed coat has uniform marks of sulfuric acid etching, then rinse with clean water and dry for use. The time of seed treatment is related to the temperature and the amount of acid added. In the case of the same amount of acid, the treatment time is short when the air temperature is high, and the treatment time is long when the air temperature is low. If more acid is added, the treatment time will be short, otherwise the treatment time will be long. Second, the method of crushing the seed coat. Put the seed on the grinding plate, 3 cm thick, turn with the mill, and when the seed coat is crushed, it will be yellow and white.

Seed treatment of Glycyrrhiza uralensis
Licorice seeds begin to germinate at 10-15 degrees, and 15-20 degrees germinate most quickly, and the germination rate of aged seeds decreases. One of the biggest characteristics of licorice is the hard seed phenomenon, which is usually between 70 and 90 percent, and it is difficult to emerge after sowing, so when seeds are propagated in production, they must be treated before sowing. The general treatment methods are as follows: ⑴ soaking seeds in boiling water, ⑵ concentrated sulfuric acid soaking seeds, ⑶ broken glass grinding. ⑷ rice mill, among which the rice mill has the best grinding effect. Generally, the rice mill is used 1-2 times before sowing.

Key points of planting and cultivation techniques of licorice
An overview of licorice, alias sweet grass root, red licorice, powder grass. Licorice GlycyrrhizauralensisFisch., a leguminous plant, was used as medicine with root and rhizome. It has the effect of clearing heat and detoxification, moistening the lungs and relieving cough, reconciling various medicines, and grilled licorice has the effect of tonifying the spleen and tonifying qi. Plant characteristic perennial herbs with stout, cylindrical roots, sweet, brownish red rind. The stem is erect, the lower part is slightly lignified. Leaves alternate; parasite pinnately compound leaves, leaflets 7 Mel 17, ovate-elliptic, both surfaces covered with glands and short hairs. Racemose flower

Licorice planting and cultivation
1. Land selection and soil preparation: cultivated licorice should choose sandy loam with deep soil layer and low groundwater level, and ploughing about 30 cm. At present, flat farming is mostly carried out, and high beds are rarely made. For good drainage and irrigation, the land can also be turned into small beds and fertilized with base fertilizer. It is best to turn the soil in autumn, and the soil moisture must be preserved in spring, otherwise it will affect seedling emergence and seedling preservation. 2. The mode of reproduction: seed propagation is the main method in production, and rhizome propagation is also possible. (1) seed propagation: soak in 60 ℃ warm water for several hours before sowing and use broken glass.

Key points of planting techniques of licorice
1. Seed treatment Glycyrrhiza uralensis seeds mature from July to August and should be harvested in time. The seed is hard, the skin is not easy to absorb water, direct seeding in the soil, the germination rate is only about 30%, before sowing with 60: 100 ℃ of water for 30 seconds heat treatment; then soaked in warm water for 1 day and night, the germination rate can reach 50%. If treated with concentrated sulfuric acid, when the seed coat blackens, rinse it in clean water immediately, then soak it in warm water, and sow the seed when it expands, the germination rate can reach more than 90%. two。 Planting method ① field direct seeding land preparation conditions are the same as field crops, can be sown in spring

Planting methods and technical requirements of licorice
The main results are as follows: 1. There are great differences in the yield and quality of licorice under different climate and soil conditions. Licorice has strong adaptability to temperature conditions, and water conditions play a decisive role in the yield of licorice. According to the author's research, in the area of temperate precipitation 300~500mm in China, the precipitation can basically meet the growth of Glycyrrhiza uralensis in general years, and it can be cultivated on the land without irrigation conditions. In order to obtain high quality transplanting seedlings, the seedling land should have irrigation conditions. In areas with annual precipitation below 200mm, in order to obtain high quality and high yield, there is not enough underground.

How to select and prepare the land with licorice
The rhizome of Glycyrrhiza uralensis has a strong germinating ability and extends horizontally under the surface to the surrounding of the old plant. One licorice can send out dozens of new plants in several years. Artificial cultivation, sowing for 3 years, new plants can be seen at a distance of 3 to 4 meters away from the mother plant. Its vertical rhizome can also take root, and the depth of the root system varies according to the soil quality and the depth of the groundwater table, generally within the range of 1 to 2 meters, sometimes up to more than 10 meters, with deep roots absorbing groundwater to adapt to arid environmental conditions.

Cultivation of Liquoric Root and Technology of Grassland Reseeding
Licorrhiza uralensis is a wild medicinal and forage plant. According to its biological and ecological characteristics, agricultural technical measures can be adopted to break the dormancy period of seeds, improve germination rate, meet the needs of water and nutrition for the growth and development of licorice, and improve its biological yield. 1. Cultivation techniques of liquorice (1) seed treatment. The seed coat was broken by rice milling machine, and the germination rate could be increased from 30% to more than 80% if the seed was not broken twice. (2) Land selection and preparation before sowing. in sandy, sandy and beach land
