(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

(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 by size, tie them into small bundles, hang them head-down on a curing rack, and slowly smoke-cure them over a fire. During smoking, pay attention to indoor ventilation and turn them frequently. After drying, rub off the fibrous roots and trim away the overly thin tail roots, and it is ready as a commercial product. Generally, those with thick, long main roots, an oily sheen, a yellow-brown outer skin, and a yellow cross-section are considered superior. The average yield is 3000 kg of dried product per hectare, and can reach 6000 kg at high yields.
