Breeding methods of Angelica sinensis

Propagate with seeds, raise seedlings and transplant.

1. The fresh seeds produced in the second year after transplanting are usually selected for seed collection. When the seed coat is blue or pink, it can be harvested, air-dried, threshed and stored.

2. The nursery land should be the leeward, shaded hillside or wasteland. Turn the ground in late May, use the burned weed ash as base fertilizer, turn it into the soil, and then rake flat to make a high border, 1.2m wide. Before sowing, apply base fertilizer, every 667m2 2500~3000kg, turn into the soil, fine and flat. Sow seeds from early to late June, open horizontal ditches according to 17~20cm, evenly sow seeds, cover a layer of fine soil, cover seeds tightly, and then cover a layer of weeds. 667 square meters of sowing 4~5kg. The suitable temperature for germination is about 20 ℃, and the seedlings emerge about half a month after sowing. At this time, the cover grass will be loosened to prevent the seedlings from being hurt when the grass is uncovered. Uncover the grass at the beginning of August. Weeds should be removed to keep weeds free in the field. Combined with weeding seedlings, it is appropriate to get rid of the weak and stay strong, and the plant distance should be about 1cm.

3. Dig the seedlings for storage in early October, dig up the seedlings by the roots, tie them into small handfuls, and store them in piles or cellar. To store, choose a cool house that does not make a fire, pile up a layer of loess in the house, and store it outdoors, choose a cool and dry place. The cellar is 1m deep and 1m wide, depending on the number of plants. It is piled up with one layer of loess and the top of the cellar is covered with soil around 30cm, which is higher than the ground.

4. It is suitable to transplant in the first and middle of April. On the finished border surface, the holes were planted in the triangle of 35cm × 25cm, and the hole was deep 16cm. It is better to choose the root diameter of the seedlings to be controlled at about 3.5mm. If the root is too large, it is easy to bolt ahead of time. If it is too small, the adaptability is poor and the survival rate is low. After planting, cover the soil while pressing, and then cover the soil without passing the root neck 2~3cm of the seedling.
