Key Techniques and Management Methods for Growing Angelica Sinensis

For Angelica sinensis cultivation, you must first choose a good planting site, then prepare the land and apply fertilizer. Then sow the prepared seeds to raise seedlings, and once the seedlings are ready, you can lift them and transplant. After transplanting, pay attention to checking for and filling in gaps in the seedlings. Finally, do a good job with field management, such as weeding and loosening the soil, topdressing, drainage and irrigation, and pest and disease control.

Field management of Angelica sinensis:

1. Checking for and filling in gaps in seedlings: About 20 days after transplanting, Angelica sinensis will begin to emerge successively. If there are missing seedlings, replant them promptly.

2. Weeding and loosening the soil: Carry out the first weeding when the seedlings are about 5 cm tall. From emergence to ridge closure, weed 3-4 times in stages, and loosen the soil along with hoeing to prevent the soil from becoming compacted.

3. Topdressing: Angelica sinensis requires a relatively large amount of fertilizer throughout its life. In addition to applying sufficient base fertilizer, it should also be topdressed in a timely manner. The suitable times for topdressing are the peak leaf growth period in late June and the root growth period in early August; these are the two peak periods of fertilizer demand. The soil in Angelica sinensis production areas and farmyard manure are generally deficient in phosphorus and potassium, so phosphorus and potassium fertilizers need to be supplemented. Usually potassium dihydrogen phosphate, diammonium phosphate, and nitrogen-phosphorus-potassium compound fertilizer are used for topdressing.

4. Irrigation and drainage: Angelica sinensis growth requires a relatively moist soil environment. Moderate irrigation during drought is beneficial for high yield. When there is excessive rain, pay attention to ditching and drainage. Especially in the later stage of growth, water must not accumulate in the field, otherwise it will cause root rot and lead to rotten roots.

5. Earthing up: When Angelica sinensis grows to the middle and late stages (after August), the root system begins to develop and grows rapidly. Earthing up at this time can promote the development of the root body and help improve yield and quality. Earthing up can be combined with loosening the soil.

6. Removing old leaves: After ridge closure, the lower old leaves of Angelica sinensis turn yellow due to insufficient light. These old leaves should be removed promptly. This can both avoid unnecessary nutrient consumption and improve ventilation and light conditions within the population.

7. Removing bolting plants promptly: In plants that bolt early, the roots gradually become lignified and turn into woody roots, losing their medicinal value. Such plants have strong vitality and consume a lot of water and fertilizer, so they should all be pulled out promptly to avoid consuming soil fertility and affecting the growth of plants that have not bolted.

Angelica sinensis has a long history of cultivation in China, and its cultivation techniques are also relatively mature. Friends who are interested may consider it.
