The seed treatment method of Glycyrrhiza uralensis-- Sand Storage treatment
If the amount of seed used is large, sand storage treatment is often used. The method is to treat it about 2 months before sowing. First soak the licorice seeds in 60 ℃ warm water for 4 hours, stir them many times, fish them out and drain them, mix them with 5 times as much fine sand as the seeds, and the humidity of the river sand is that it can be seen by hand without dripping. Then put the well-mixed seeds into a wooden box, surrounded by wet sand of unmixed seeds, and then covered with 3-5cm thick wet fine river sand. Finally, put the seed box into the prepared cellar.

Cultivation techniques of licorice
Liquoric root, also known as sweet grass, sweet root, has the effect of harmonizing medicinal properties, reducing or alleviating drug toxicity, moistening lungs, and also has the characteristics of cold resistance, heat resistance, drought tolerance, fear of waterlogging and liking light. It is an excellent plant for windbreak and sand fixation. Its cultivation techniques are as follows: land selection and preparation should select sandy soil with deep soil layer, deep groundwater level and good drainage, soil salt content should not exceed 0.2%, rainy or sticky soil and poor drainage should not be planted, because the root is easy to rot or the main root is short, there are many branch roots and hairy roots, and the economic value is not high. It is best to choose a flat nursery ground

Timely cultivation of licorice
1. Seed germination habits (1) the water absorption of licorice seeds and the emergence rate of germinated licorice seeds are low, generally about 10%, so they should be treated before sowing, the untreated seeds absorb water very slowly, and most of the seeds do not absorb water; the seeds treated with concentrated sulfuric acid absorb water very quickly, reaching more than 100% in 4 hours. Generally speaking, when the water absorption is more than 100%, it has a very neat germination ability. If the water absorption is different, the germination rate is different. when absorbing water for more than 1.5 hours at 2O ℃, the germination rate is more than 80%, and the water content is about 95%.

Cultivation techniques of licorice
Licorice belongs to perennial plants of Leguminosae, and the medicinal parts are roots and rhizomes. It contains 11% triterpenoids, glycyrrhizin, followed by flavonoids such as glycyrrhizin, glycyrrhizin, isoglycyrrhizin, isoglycyrrhizin and so on. Xingping taste sweet, harmony and emergency, moistening the lungs, detoxification, reconciling various medicines, is an indispensable medicine in many traditional Chinese medicine prescriptions. (1) selecting and preparing land. Licorice likes dry climate and is suitable for sandy loam with deep soil layer and low groundwater level, which can achieve more silty, less fiber and sweet taste.

Seedling raising and transplanting techniques of Glycyrrhiza uralensis
The seedling base of Glycyrrhiza uralensis requires good irrigation conditions, flat land, fertile land, unlimited land size, but also courtyard development. The sowing time is from April to August every year, and 10 kg of treated seeds can be sown per mu. Strip sowing was used, the row spacing was 15 cm, and the number of seedlings per mu was 120000 ~ 150000. The seedlings of licorice sown in spring were transferred in spring, and in the third year in summer and autumn, the row spacing was 35 cm, the furrow depth was 8 cm, and the plant spacing was 8 cm. Using the flat planting method, per mu

Seedling raising techniques of Glycyrrhiza uralensis
Select sand and loam with low groundwater level and deep soil layer, but it must be water land. When the surface temperature reaches 15 ℃, 3000 kg of farm manure and 40 kg of American diamine or phosphorus nitrate are applied per mu, and then 40-50cm is ploughed deeply (otherwise there are many short branches of seedling roots, up to less than the prescribed quality standard), and the flat bed is watered once, and the amount of water is to make the soil reach the state of black soil moisture. (that is, after picking it up by hand and throwing it into a cake without scattered shape), after three or five days of shallow ploughing, you can open a ditch and sow seeds, according to the method of sowing seedlings, row spacing 2.

Transplanting techniques of Glycyrrhiza uralensis
Generally, it takes place in late autumn and early spring, before the land is frozen in late autumn, before and after Ching Ming Festival in early spring, and no later than mid-April. On the basis of last year's autumn ploughing, the transplanting land should make a bed (the width of the border is determined by row spacing 50cm, depending on several rows of the border), and then fertilize, dig up the seedlings raised last year after thawing, and remove the aboveground and lower growing points for reserve. In the whole field, trench according to the row spacing 50cm, deep 12cm, and then put the seedlings flat on the bottom of the ditch, the head inclined to the inside slope, the slope is 10 degrees. It takes 2 lines to put the seedlings.

Rust control of licorice
The pathogen is a kind of basidiomycetes in fungi, which mainly harms leaves. The yellow-brown blister unilateral disease spot appeared on the back of the susceptible leaf, and the brown powder was released after the epidermis ruptured, that is, the summer spore pile and summer spore of the pathogen, and the dark-brown winter spore pile was formed from August to September. Prevention and control methods: 1. The leaves of the diseased plants were burned. two。 At the initial stage of the disease, spray Baume 0.3-0.4 stone sulfur mixture or 97% diazepam sodium 400-fold solution.
