How do you save seeds when growing Angelica dahurica? Please explain the method
Angelica dahurica is propagated by seed. Establish a high-quality seed breeding field at the Angelica dahurica production base, carry out good-variety breeding and germplasm preservation well, and ensure seed quality. When harvesting Angelica dahurica, select roots that are uniform in thickness, moderate in size, vigorous, and free of pests and diseases, and transplant them into the seed field. Choose fertile soil with irrigation and drainage conditions for the seed field, plow deeply to 30 cm, dig holes about 30 cm deep at a spacing of 60 cm between plants and rows, apply 1.5--2 kg of farmyard manure per hole, mix it evenly with the soil, then plant the Angelica dahurica roots in the holes, fill the soil, firm it by trampling, and water. Hoe the ground before the Start of Winter (Lidong). Around Minor Snow (Xiaoxue), mound 15 cm of soil over each plant to protect against freezing. Around Qingming the following spring, remove the covering soil, level the soil around the plants, clear weeds, and water during dry periods. When the seedlings are 30 cm tall, apply a bolting fertilizer, using 10-15 kg of urea per mu. The plants flower and set seed from June to July. Keep the inflorescences that bloom first on the main stem and the tips of the primary branches, and prune off flower branches that bloom too late so the seeds mature uniformly. When the seeds turn from green to yellowish white, harvest them. Hang them in a ventilated place to dry, thresh out the seeds, put them in clean gunny bags, and store them in a ventilated place.
