Key Technical Points for Harvesting and Processing Codonopsis pilosula
(1) Harvesting: Direct-sown Codonopsis pilosula needs 3 years before it can be harvested, while transplanted seedlings are best harvested in the second year after transplanting. In autumn, after the above-ground stems and leaves turn yellow and wither, choose a sunny day and dig carefully and deeply, turning out the whole root, avoiding cuts and breakage so that the sap does not flow out and form black scars, which would reduce quality. (2) Processing: Wash the harvested Codonopsis pilosula, grade it, and process each grade separately. First spread it on a drying mat in the sun for 2-3 days; when the roots become soft from drying, tie each grade of Codonopsis pilosula into small bundles, hold the root head with one hand, and with the other hand rub downward along the root several times. The next day, sun-dry again, and in the evening gather them into ox-horn bundles, each weighing 1

Detailed Explanation of Harvesting and Processing Methods for Codonopsis pilosula
For direct-sown fields, harvest in the third year; for transplanted fields, harvest after two years of growth following transplanting. For medicinal Codonopsis pilosula, the harvest period runs from when the aboveground parts wither until before the ground freezes, but the best quality is obtained when harvested within the half-month before and after the White Dew solar term. When harvesting, first remove the support stakes, cut off the stems and vines, then dig up the roots. Take care not to damage the roots while digging, to prevent the loss of sap. Remove the residual stems from the dug roots, wash off the soil, and sort them by size, length and thickness into old, large and medium grades for drying in the sun. After drying until half-dry, briefly blanch in boiling water, then sun-dry or oven-dry (oven-drying must use only a low fire, with the temperature around 60°C

Detailed Explanation of Harvesting Methods and Primary Processing Techniques for Codonopsis pilosula
1. Harvesting and Storage of Codonopsis pilosula Seeds Although one-year-old Codonopsis pilosula plants can produce a small amount of flowers and seeds, many of the seeds are shriveled and do not easily sprout after sowing, or the seedlings that emerge are weak in growth, so they are not suitable for seed use. Two- to three-year-old Codonopsis pilosula plants produce more flowers and seeds, with plump grains, high yield, and good quality, and the seedlings grown from them are robust, making them suitable for seed use. Codonopsis pilosula seeds are generally harvested from September to October, when the fruits of two- to three-year-old Codonopsis pilosula turn yellowish-white and the seeds turn brown. After harvesting, dry them in the shade, place them in cloth bags or burlap bags, and store them at low temperature; the suitable temperature is below 10°C. 2. Codonopsis pilosula
