1. Cultivated weeding: after the emergence of the seedlings, the cultivars should be cultivated and weeded in time to ensure that weeds are not found in the fields. The ridges and ridges can be used for three shovels and three rakes. This is the key to high quality and high output. Conditioning can be closed and weeding before sowing after sowing, with douhuanglong, (20% chlorpyrifosulfuron) WP 2 bags/acre with acetochlor 2-4 bottles/mu spraying field. After emergence, monocotyledonous herbicides can be sprayed to eliminate weeds. 2. Dianmiao Dingmiao: combined with cultivator weeding height 3-5 cm seedling spacing 6 ~ 7 cm, seedling height 5-10 cm Dingyou spacing 10-15 cm. A variety of seedlings can be denser, with a spacing of 3-5 cm. 3. Topdressing: Combining cultivating and weeding 2000 kg per acre applied to afforestation with 15 kg superphosphate mixed. Apply the ditch to the ridge. Foliar fertilizer can also be sprayed to increase yield. 4. Irrigation: Although licorice is a deep-rooted drought-resistant plant, its roots are shallow at the seedling stage and the drought resistance is not strong. Therefore, in case of drought during seedling stage, watering should be promptly conducted to maintain the water supply during the seedling period. In the adult stage, water is rarely applied. Should pay attention to the rainy season in July-August drainage, do not have water in the field to prevent rot. 5. Picking buds: 3-4 years old flowers. Plots that are not seeded fields should be harvested at the bud stage in a timely manner to prevent consumption of nutrients, increase root yield and improve quality.
