Detailed Explanation of Angelica Harvest Time and Methods
For autumn direct-seeded angelica, harvest occurs in the second year; for transplanted angelica, harvest occurs in the same year, after the plants turn yellow and withered in mid-October. Natural conditions vary from place to place, so harvest times differ to some extent. For example, in Minxian, Gansu, harvest is 3 to 5 days after Frost's Descent; in production areas of Sichuan, harvest is around Frost's Descent; in Yan'an, Shaanxi, it is in late October or early November. Harvesting should not be too early or too late. If too early, the angelica is not yet fully mature, which reduces yield and quality; if too late, the soil freezes, the roots become brittle and break easily, causing excessive loss. Generally, it is best to harvest before the soil freezes and when the plants are yellow and wilted. About 10 to 15 days before harvest, first cut off the angelica stems and leaves, leaving stubble about 3 cm tall so the plants can be identified during harvest. This allows the ground to be exposed to the sun and speeds up maturation. At the same time, livestock trampling should be prevented to avoid rotting of the heads. When harvesting, dig with a hoe: first hollow out the soil beneath the plants, then dig them over from above and take them out. This allows the entire root to be dug out and prevents breaking or injuring the roots. After digging, in conjunction with turning the soil, pick up once more any roots that were missed or broken during digging. After harvesting, transport them back to the processing site and tie them into bundles for processing. Generally, the yield is 100 to 150 kg of dried angelica per mu, and high-yielding fields can reach 250 to 300 kg per mu.

Detailed Explanation of Angelica sinensis Harvesting and Processing Techniques (Part 3)
For autumn direct-seeded plants, harvest in the second year; for transplanted plants, harvest in late October of the same year, when the plants turn yellow and withered. Dig up the whole plant, shake off the mud and sand, and air-dry for 2-3 days until the roots become soft. Then remove the stems, leaves and fibrous roots, sort them by root size, tie them into small bundles, hang them head-down on the curing rack, and smoke and roast them slowly with smoke and fire. During smoking, pay attention to indoor ventilation and turn them frequently. After drying, rub off the fine hairs and fibrous roots, and they are ready as a commercial product. Generally, 667 sq m can produce about 150 kg of dried product. High-yield fields can reach 400 kg.

Key Harvesting and Processing Techniques for Angelica sinensis (Danggui) (Part One)
(1) Harvesting For direct-sown plants, dig in mid-to-late October of the second year; for seedlings raised in a nursery and then transplanted, dig in mid-to-late October of the same year, when the plants have withered and turned yellow. Digging too early results in roots that are not plump and solid, with low yield and poor quality; digging too late means the soil has already frozen, making digging difficult and prone to breaking the roots. Before harvesting, first cut off the above-ground stems and leaves and sun-dry them for 3-5 days, so that the roots become fuller and more solid; then carefully dig out the entire root. (2) Processing After harvesting, angelica sinensis must not be piled up. First clean off the soil, choose a high, dry, well-ventilated spot, spread the roots out to dry until the roots become soft, or sort them

Origin Processing Methods and Technical Key Points for Angelica sinensis
The processing of Angelica sinensis directly affects the quality and medicinal efficacy. Because fresh Angelica sinensis contains more than 60% water and the medicinal component volatile oil, if processing is not timely or not done well, it will become moldy and deteriorate. Processing methods and procedures for Angelica sinensis: 1. Sorting and bundling. The recovered Angelica sinensis should be sorted promptly, and roots that are rotten, especially water-rotted, should be picked out to prevent the spread and infection of water rot. The selected Angelica sinensis is spread under the eaves in a dry, ventilated place to air-dry for about 7 days so that the moisture evaporates and the roots become soft, then they are bundled with willow twigs or tree bark. Each bundle of fresh

How to Propagate Angelica Sinensis? A Detailed Guide to Common Propagation Methods
Propagate by seed, then raise seedlings and transplant. 1. Seed collection: usually use fresh seeds set in the second year after transplanting. When the seed coat turns azure blue or pink, the seeds can be harvested, air-dried, threshed, and stored for later use. 2. Seedbed site: choose a sheltered, sunny, shaded hillside or wasteland. In late May, turn the soil, use the ash of burned weeds as base fertilizer, dig it into the soil, then rake it level and make raised beds 1.2 m wide. Before sowing, apply base fertilizer again, 2500-3000 kg per 667 sq m, dig it into the soil, and break up and level the soil finely. Sow from early to late June

Key Points of Angelica sinensis Propagation Techniques and Detailed Explanation of Seedling Methods
Angelica sinensis is propagated by seed, generally using the method of raising seedlings and transplanting, though direct sowing can also be used. 1. Seedling raising and transplanting (1) Seed selection: After seed selection, Angelica sinensis yields about 14.6 kg more per mu than unselected seeds. The main selection method is ear selection. At harvest time, when the seed coat turns sky blue or pink and the flowering stem droops, select fruit ears that have the characteristics of this variety, grow well and vigorously, are free of pests and diseases, and are highly mature; cut them off together with the flowering stem, dry them in a ventilated and dry place, thresh, and store for later use. Because Angelica sinensis seeds do not mature uniformly, har

After harvesting, shake off the soil, pick out the rotten roots, remove the remaining leaf stalks, and after the moisture has slightly evaporated, tie them into flat bundles weighing 0.5~1 kg and place them in a smoking shed. Inside the smoking shed, build a 130 cm high rack, lay bamboo strips on top, and place the angelica bundles on it alternately flat and upright, with a thickness of 30~50 cm. Use soybean stalks, wet poplar, willow wood, etc. as fuel; after lighting, spray water so that it only produces smoke and no open flame, smoke them to color, until the surface of the angelica turns reddish red, then switch to coal fire or firewood (grass) fire and smoke for about 10 days, then turn over

Key Techniques and Detailed Methods for Seed Saving of Angelica sinensis
For raising seedlings and transplanting, seeds of medium maturity produced from flowering in the third year should be used. A single plant, besides the main bud, has many lateral buds. Both the main bud and the lateral buds can bolt, flower and set seed. Flowering branches that bear seeds can also grow from the axils of the main stem. Because the growth periods of the various flowering branches differ, flowering times and seed maturation occur in succession. Therefore, when collecting seeds, one must frequently observe in the field. Looking down from the top of the flowering stem, when the first umbel appears pink, the second umbel appears light red, and the third umbel appears pale yellow, it is time to harvest (generally in early to mid-August). Seeds that are over-mature, after seedling raising
