Codonopsis pilosula harvesting and processing
The main results are as follows: (1) the direct seeding of Codonopsis pilosula can be harvested in 3 years, and it should be harvested in the second year after transplanting. When the stems and leaves on the ground are yellow and withered in autumn, choose a sunny day, dig carefully and dig out the whole root to avoid digging injury and breaking, so as to avoid the outflow of slurry, form a black scar and reduce the quality.
(2) the harvested Codonopsis pilosula was washed and graded and processed separately. First put it on the mat and spread it for 2-3 days. When the ginseng becomes soft, tie up all levels of Codonopsis pilosula into small handfuls, hold the root in one hand and knead it downwards for several times. The sun will be out again the next day, and the horn will be harvested in the evening, each weighing 1-2 kg. Then, place the plank and press it repeatedly and continue to dry it to become a commodity. Dry over 60 ℃ fire on overcast and rainy days.

Prevention and treatment of diseases of Codonopsis pilosula
First, rust mainly harms the stems and leaves of Codonopsis pilosula. Control methods: clean the countryside and eliminate weeds and diseased plants in the field. At the initial stage of the disease, 25% of the powder was sprayed with 1000-1500 times, or 90% of the sodium was sprayed with 400 times of sodium for prevention and treatment. Spray once every 7 to 10 days, 2 times in a row. Second, root rot mainly harms the roots of Codonopsis pilosula. The method of control was to increase the application of phosphorus and potassium fertilizer from July to August. Before transplanting Codonopsis pilosula, soak the root with 1000 times solution of 50% methyl topiramate wettable powder for 5 minutes. At the time of onset

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 ℃).
