Management of Angelica sinensis in winter
Direct seeding Angelica combined with topdressing before winter, cover the seedlings with manure or cover the seedlings with about 1 cm of fine soil to protect them from frost damage; Angelica sinensis should do a good job of storing seedlings in winter when raising and transplanting Angelica sinensis; in order to improve the yield and quality of seeds, seedlings with strong and uniform growth in high or semi-mountainous areas should be selected before harvest. In the future, the aboveground part of the remaining plant will be cut off, remove weeds, let it survive the winter naturally, and often take care of it to prevent livestock from trampling, resulting in lack of seedlings. When weeds grow in the next spring, they can be pulled out by hand; at this time, the root system is covered with soil surface, and weeding and fertilization should not be used to avoid cutting off the root system and hindering the growth of the plant.

Cultivation and Management of Angelica sinensis
The transplanted seedlings loosen the soil and weed for 3 times in one year, and the first time when the seedling height is 3~5cm. After weeding, topdressing was applied for the first time, 1500kg to 2500kg of sparse human and animal manure per 667m2, and 2500~3000kg for rotten stable manure, compost or fire soil ash per 667m2 for the second and third times. Bolting seedlings should be removed in time and watered during drought, but watering is prohibited in the later stage so as not to cause rotten roots. Early bolting: the key problem of Angelica sinensis in production is early bolting (in the year of transplantation). General early smoking

Seedling transplanting and direct seeding propagation of Angelica sinensis
1. Seedling transplanting (1) fresh seeds bearing fruit in the second year after transplanting should be selected for seed selection. Before and after the Beginning of Autumn, when the seed epidermis is blue or pink and the scape is drooping, cut off the scape together and put it in a ventilated and dry place to dry, threshing and storage. Avoid exposure, baking and rain. (2) sowing seedlings is usually sown with picking around the beginning of autumn, and it is suitable to sow seeds from mid-August to early September in low-altitude areas with slightly higher temperature. Timely sowing can avoid early bolting of Angelica sinensis. Too early, the seedling growth period is long.
