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.
At present, in addition to artificial weeding, chemical herbicides are often used to control weeds. Artificial licorice in our county is now popularizing the following three chemical herbicides: Acetochlor, Shitianbu and Doucaote. Practice has proved that the use of chemical herbicides is an effective measure to ensure the healthy growth of licorice, increase yield, improve quality and save labor. This paper introduces the application methods of the above three commonly used licorice herbicides.
Acetochlor and Shitianbu are both closed agents with similar herbicidal effects. Timely application can restrain the germination of many kinds of weed seeds, the application rate is 200ml per mu (1.5 mu per bottle is suitable), and infiltrate into the water before spraying or watering. The application time was controlled before the weed seeds germinated and unearthed, but had no effect on the unearthed weeds. The limited period is 2MQ for 3 months, and it is recommended to apply it twice a year.
2. Doucaote: the special validity period of legume crops is long, and it is sensitive to non-legume crops. It is not suitable to plant other crops within three years, 500ml per bottle, with an area of 2.5 mu, once a year. To the thrush grass (commonly known as: sesame oil) does not work, immediately after spraying with Quine and Lingshu eyebrow grass.

Cultivation techniques of ditching and direct seeding of licorice
Glycyrrhiza uralensis Fisch is a deep-rooted plant. The cultivation technology of ditching and direct seeding can solve the unfavorable factors such as seedling raising, transplanting, low yield and long growth cycle, and greatly improve its economic benefits. * * Yili Tex County belongs to the continental climate type of the north temperate zone, and the natural geographical environment is very favorable for the growth of licorice. In 2005, we used ditch planting deep root plant machinery to plant licorice for the first time in Xinjiang, which changed the conventional licorice planting pattern. Now the ditching direct seeding cultivation techniques are introduced as follows. 1 selection of land, application of base fertilizer and selection of fertilizer for soil preparation

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.
