Key cultivation techniques for Angelica sinensis seedling transplanting and direct seeding propagation
1. Seedling transplanting (1) Seed selection: Fresh seeds set in the second year after transplanting should be selected as seed. Around the Start of Autumn, when the seed coat turns sky blue or pink and the flowering stems droop, cut them off together with the flowering stems, place them in a ventilated and dry place to dry, then thresh and store for later use. Never expose to strong sun, roast, or rain. (2) Sowing and seedling raising: Generally sow around the Start of Autumn, sowing immediately after harvest; in lower-altitude areas with slightly higher temperatures, sowing from mid-August to early September is suitable. Timely sowing can avoid early bolting of Angelica sinensis. If too early, the seedling growth period is long,

Detailed Explanation of Licorice Cultivation and Grassland Reseeding Techniques
Licorice (Glycyrrhiza) is a wild medicinal and forage plant. Based on its biological and ecological characteristics, adopting agricultural technical measures can break seed dormancy and increase the germination rate; meet the water and nutrient requirements of licorice growth and development, and increase its biomass yield. 1. Licorice cultivation techniques (1) Seed treatment. Use a rice mill to scratch the seed coat, taking care not to crush the seeds; milling twice gives the best results, and the germination rate can be increased from 30% to over 80%. (2) Site selection and pre-sowing land preparation. On sandy land, sand-covered land, and beach land types

Direct seeding cultivation techniques for licorice in the Hexi arid region
Licorice is the most commonly used bulk medicinal herb, hailed as the king of medicines. The currently cultivated species is Glycyrrhiza uralensis (Ural licorice), a plant of the genus Glycyrrhiza in the Fabaceae family. It is highly water-saving, drought-tolerant and cold-tolerant, and is an excellent windbreak and sand-fixing vegetation for arid and semi-arid desert areas. The medicinal part is the dried root, which not only has effects such as tonifying the spleen and boosting qi, relieving cough and expelling phlegm, clearing heat and detoxifying, and harmonizing the properties of medicines, but is also widely used in daily necessities, light industry, animal husbandry and the food industry. Minqin County, located on the edge of the Badain Jaran Desert and the Tengger Desert, is a major production area for cultivated licorice in Gansu Province

Detailed Explanation of Direct Seeding Cultivation Techniques for Licorice
Cultivation Techniques Site Selection Licorice is a deep-rooted plant, so flat, fertile, loose sandy soil or loam should be selected for planting. The best preceding crops are wheat, corn, and melon or vegetable fields, and continuous cropping with sugar beet or sunflower should be avoided. Land Preparation and Fertilization Deep plow the selected land to more than 26 cm, apply 2000 kg to 3000 kg of fully decomposed organic fertilizer per mu, and 18 kg to 20 kg of diammonium phosphate, then harrow the soil finely, level it, and make beds. The bed ridges should be 20 cm to 30 cm wide and 20 cm high, the beds should be 2 m to 2.5 m wide, and the bed length depends on the terrain.

Detailed Explanation of Licorice Trench-Sowing Direct-Seeding Cultivation Technology
Licorice is a deep-rooted plant. Adopting trench-sowing direct-seeding cultivation technology can solve unfavorable factors such as licorice seedling raising, transplanting, low yield, and long growth cycle, greatly improving its economic benefits. **Tekes County in Ili belongs to the northern temperate continental climate type, and its natural geographical environment is very suitable for licorice growth. In 2005, we used the deep-rooted plant trench-planting machine for licorice cultivation for the first time in the whole of Xinjiang, changing the conventional licorice planting model. The trench-sowing direct-seeding cultivation technology is now introduced as follows. 1 Site selection, base fertilizer application, land preparation Select fertile

Detailed Explanation of Key Techniques for Direct Seeding and Seedling Cultivation of Schisandra chinensis in Open Fields
Select a sunny plot with loose soil, flat terrain, moist soil and no water accumulation, and make a low bed 1.2---1.4m wide, 10m long, with a level surface. Sowing uses the drill method. Before the autumn freeze, open shallow furrows 2-3cm deep on the prepared seedbed at a row spacing of 15cm, sow 100g of seeds per bed, cover with soil 3---4cm thick, water thoroughly, press down lightly, then cover with 10cm of leaves or a layer of rice straw to maintain moisture and protect against cold, and remove it when the seedlings emerge. To prevent damping-off and other soil-borne diseases,

Discovery of a Wild Self-Seeding Fertile Pinellia Plant and Analysis of Its Utilization Prospects
Since 1988, we have conducted surveys of wild Pinellia ternata variety resources in the Yimeng Mountain area and research on artificial cultivation techniques. During many years of investigation and study, we discovered a single Pinellia ternata plant that can self-pollinate and set seed under wild conditions. After artificial domestication and cultivation, one 1.5 g Pinellia tuber can produce 40 to 50 seeds in one year, thereby solving the problems of low natural seed-setting rate and the lack of five usable [varieties] in production, and opening a path for improving the propagation rate of Pinellia ternata. 1 Botanical characteristics: the plant is 10 cm tall
