Second application of licorice herbicide
Weeds can seriously affect the yield and quality of licorice. It competes with licorice for sunlight, water and nutrients. Some weeds are intermediate hosts of licorice crop diseases and insect pests, helping to spread and spread diseases and insect pests. Especially artificial cultivation of licorice at seedling stage, if weeds are not eliminated in time, a large number of dead seedlings will be caused, even seed destruction. Now chemical herbicides are often used in addition to artificial weeding. Artificial licorice in our county is now promoting the following three chemical herbicides: Acetochlor, Shitianbu and Doucaote. Practice has proved that the use of chemical herbicides is the guarantee.

Cultivation techniques of licorice
Liquoric root belongs to leguminous perennial vegetation plant, medicinal part namely root and rhizome. It contains 5 - 11% of triterpenes, glycyrrhizin, followed by flavonoids such as liquiritin, liquiritin, isoliquiritin, isoliquiritin, etc. It is an indispensable medicine in many traditional Chinese medicine prescriptions. (1) Land selection. Licorrhiza likes dry climate, suitable for sandy loam with deep soil layer and low groundwater level, which can achieve silty soil with more fiber, sweet taste and high quality.

What are the technical points of seedling raising and transplanting of licorice?
The main results are as follows: (1) Land selection and preparation: licorice has strong adaptability and can be planted in general soil, but the sandy loam with deep soil layer, loose soil and good drainage is the best. Combined with deep ploughing in autumn, 2000 kg of rotten farm manure and 20 kg of diammonium phosphate or calcium superphosphate were applied per mu, and then raked flat to make fine beds. (2) Seedling raising and seedling protection: seedlings can be raised and sowed at the beginning of May, the seedling land will be watered before sowing, and when the surface is slightly dry, the narrow row planter will be used for sowing, the seed consumption per mu is 8 million kg, and the seedling protection plant is 100000-120000 plants. After Miao Qi, the soil moisture is preserved by watering, and the field is maintained during the growing period.

Seedling raising and transplanting techniques of Glycyrrhiza uralensis
Licorice is an important medicinal material, with the strengthening of national ecological environment protection, the utilization of wild resources has been very limited, licorice seedling transplanting technology has become very important. Licorice is a perennial herb of Leguminosae, which is listed as a key specially controlled medicinal material by the state. Glycyrrhizic acid as a sweetener is 300 times sweeter than sucrose and is one of the best natural sweeteners found so far. The state explicitly orders licorice as a national second-class protected plant, which is not allowed to be picked casually, and the contradiction between the supply and descent of licorice is intensified. Therefore, the artificial cultivation and high yield and high quality cultivation of licorice were studied.

What are the growth habits of licorice?
Licorice, alias "Sweet Grass Miao", is a perennial herbal medicine. Licorice likes the ecological environment with sufficient light, less rainfall, hot summer, cold winter and large temperature difference between day and night, which has the characteristics of light, drought, heat, salt and cold tolerance. It is suitable to grow in sandy soil with deep soil layer, loose soil and good drainage. Licorice seed coat is thick and solid, poor water permeability, not easy to germinate, need seed treatment before sowing, the treatment method is to use coarse sand and rice grinder to grind the seed coat to make the seed coat rough and increase penetration.

licorice carambola
This product belongs to the cold fruit category, the raw material used can be dried carambola or salt embryo, the processing technology is as follows: 1, raw material treatment: dried carambola should be soaked for about 1 hour, the purpose is to make the dried product rehydrated to reach a semi-dry state to quickly absorb the liquid. If it is a semi-finished salt embryo, it should be soaked and desalinated. The desalination degree can retain 1-2% of salt. It should be dried to a semi-dry state for later use. 2. Preparation of feed solution: 10 kg of dried tangerine peel, soak in plenty of water to remove bitterness, or boil for 10 minutes and then soak in water.

Processing of licorice red bayberry
Licorice red bayberry belongs to cool fruit products, and the raw material red bayberry is the use of its finished salt embryo. The processing technology is as follows: 1. Raw material treatment: the process of processing fresh bayberry into semi-finished products is as follows. Marinate with 20% salt, one layer of fruit and one layer of salt. Add a layer of salt to the top. after pickling for more than 10 days, the raw materials are picked up from the salt water and exposed to the sun until the semi-finished salt embryo is produced after the salt frost is produced, which is further processed from the salt embryo. First of all, desalination, immersion to remove the degree of desalination of salty taste. Generally leave about 2% of the salt, there is no need to remove the salt completely.

Licorice aphid
Harm young leaves, twigs, flowers and fruits. The sucking juice of adults and nymphs can make the leaves yellowing and fall off in severe cases, affecting fruiting and commercial yield. Control method: ① is not allowed to be planted next to legumes. During the onset of ②, 40% dimethoate EC was sprayed with 1000 times.

Seed selection and seed treatment of licorice
Ural Glycyrrhiza uralensis with high content of glycyrrhizic acid and glycyrrhetinic acid was selected. Seed treatment licorice seed coat is hard, impervious, impervious, not easy to germinate, untreated seed germination rate is only 30%-40%, while after skin-breaking treatment, the germination rate can reach more than 90%, so the seeds must be pretreated before sowing. The method adopted is as follows: soak the seeds in 60 ℃ water, cover them with wet cloth for 4 ~ 6 hours to absorb water and expand, dry and then sow.
