Harvest of Angelica sinensis

Angelica autumn-direct seeding in the second year, transplanting in the same year, in mid-October after the plant withered harvest. Natural conditions vary from place to place, and harvest time varies to some extent. For example, Min County in Gansu Province harvests 3~5 days after frost, Sichuan production areas harvest before and after frost; Yan 'an in Shaanxi Province harvests in late October or early November. Harvesting should not be too early or too late, too early, Angelica sinensis is not fully mature, it will reduce the yield and quality, too late, the soil freezes, the roots become brittle, easy to break, and the loss is too large. Generally speaking, it is best to harvest before the soil freezes and when the plants are yellow. 10~15 days before harvest, cut off the stems and leaves of Angelica sinensis and leave about 3 cm of stems and stumps for identification at harvest time. This will expose the ground to the sun and accelerate ripening. At the same time, livestock should be prevented from trampling and causing head rot. When harvesting, dig with a hoe, first hollow out the bottom of the plant, and then dig it down from above, so that the roots can be dug completely without breaking the roots. After digging, combine with digging, and then pick up the roots missed or broken. After harvest, it is transported back to the processing site and bundled for processing. Generally, the yield per mu of dry angelica is 100~150 kg, and the yield per mu of high-yield field can reach 250~300 kg.
