Harvest and processing of Codonopsis pilosula
The direct seeding field was harvested in three years, and the transplanting field was harvested in two years. Codonopsis pilosula was harvested during the period from aboveground withering to freezing, but the harvest quality was the best within half a month before and after Bailu Festival. When harvesting, pull out the bracket, cut off the stem, and then dig the ginseng root, be careful not to hurt the root, in order to prevent the loss of juice. The dug ginseng root is removed from the residual stem, washed the soil, divided into old, large, medium and graded according to size, length and thickness, and dried in semi-dry, then slightly scalded in boiling water and then dried or dried (drying only over a low heat, at a temperature of about 60 ℃).

Harvesting and preliminary processing of Codonopsis pilosula
1. Harvest and storage of seeds of Codonopsis pilosula although annual plants of Codonopsis pilosula can blossom and bear fruit, there are many shrunken seeds, and the seedlings that are not easy to emerge or grow are weak after sowing, so they are not suitable for planting. The 2-year-old Codonopsis pilosula plants have more flowering and fruiting, full grains, high yield and good quality, and the seedlings grow healthily and are suitable for seed use. The seeds of Codonopsis pilosula are generally harvested when the fruits of 2 ~ 3 years old are yellow and white and the seeds turn brown from September to October. Dry after harvest, should be packed in cloth bag or linen bag, suitable for low temperature storage, suitable temperature below 10 ℃. two。 Codonopsis pilosula
