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

Harvesting and Processing Methods and Key Technical Points for Pinellia ternata
Those propagated from tubers are harvested in the same year or the following year, while those grown from seeds can only be harvested in the 3rd to 4th year. Harvesting is generally carried out in summer or autumn after the stems and leaves wither and the plants fall over. After digging them out, pack them in baskets, wash off the mud and sand while they are still fresh, put them into gunny sacks and shake off the outer skin, then pour them out and wash the outer skin clean with clean water. Scoop them out and dry them in the sun to obtain raw Pinellia ternata. Generally, the yield of fresh tubers is 500-750 kg per mu, with a drying ratio of about 30%.

Detailed Explanation of the One-Year Three-Harvest Cultivation and Processing Technology for Pinellia (Pinellia ternata)
I. Land Selection and Preparation For planting Pinellia, loose and fertile soil is best. When preparing the land, apply 3000-5000 kg of farmyard manure per mu, 25-30 kg of phosphate fertilizer, and 100 kg of plant ash; do not apply ammonium bicarbonate. Plow deeply and harrow finely, with beds 1.3 m wide and 0.17 m high, and ditches 0.3 m wide; tall crops such as wheat, corn, sorghum, or kenaf can be intercropped in the ditches. II. Sowing Method Usually tuber propagation is used, allowing three plantings and three harvests in one year, namely planting in April and harvesting in July; planting in July and harvesting in October; planting in October and harvesting in April of the following year. The amount of seed tubers used per mu varies with

Detailed Explanation of Harvesting and Processing Methods for Pinellia ternata
I. Harvesting is generally carried out in summer and autumn after the stems and leaves have withered and the plants have fallen over. In the southern provinces, it can be done in July-August. The method is: choose a sunny day, use a hoe to dig a furrow 12-20 cm deep along the rows, dig out the Pinellia ternata tubers one by one, shake off the soil, and remove the coarse skin and fibrous roots from the surface of the medicinal material. II. Processing: Wash the fresh Pinellia ternata clean of mud, grade them into large, medium, and small sizes, put them into burlap sacks separately, first tap them lightly on the ground a few times, then pour them into a vat of clean water and rub them repeatedly, or put the tubers into a bamboo basket and beat them with a wooden stick in running water or use a peeling machine to remove the skin. After washing

1. Flower-picking time: The picking time is from 9 to 12 o'clock in the previous year; it is not suitable to pick when there is dew or on rainy days, but it can also be picked if there is drying equipment. Flowers picked in the morning are blue-white, heavy, easy to dry, have a strong fragrance, a high rate of commercial product output, and good quality. Flowers picked after noon and on cloudy days are poorer in quality and have a low processing rate. From the flower's development process...
