Methods for Weed Control in Codonopsis pilosula and Key Technical Points
For fields where annual grass weeds such as barnyardgrass, crabgrass, foxtail, and giant foxtail are the main weeds, use herbicides such as napropamide (sethoxydim), quizalofop-p-ethyl, and fluazifop-p-butyl. ①2% sethoxydim emulsifiable concentrate at 75-100 g per 667 sq m. ②5% quizalofop-p-ethyl emulsifiable concentrate at 75-100 g. ③15% fluazifop-p-butyl emulsifiable concentrate at 75-100 g. Dilute the application rate in 15-20 kg of clean water and spray the stems and leaves of the weeds. Choose a sunny, windless day between 9-11 a.m. or after 4 p.m.

Codonopsis pilosula 8917-2 Variety Introduction
8917-2 is a new Codonopsis pilosula line in China developed through crossbreeding by the Dryland Agriculture Research Institute of Dingxi Prefecture, Gansu Province. It shows strong advantages such as high and stable yield, drought and cold resistance, and wide adaptability. It increases yield by 20%-30% compared with Shanxi Ludang Codonopsis and Gansu Baitiao Codonopsis, producing 150-200 kg of dried product per 667 sq m, with the highest reaching 250 kg. The key points of its seedling raising and cultivation techniques are briefly introduced as follows. 1. Seedling raising The seedling field should be finely cultivated and fully applied with base fertilizer. Apply 2,500 kg of decomposed farmyard manure per 667 sq m, additionally apply 100 kg of cake fertilizer

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

Methods for Controlling Underground Pests of Codonopsis pilosula and Key Technical Points
The main underground pests harming Codonopsis pilosula are white grubs, cutworms and mole crickets; the above-ground pest is spider mites. Control methods for underground pests: use poisoned soil and poisoned bait to lure and kill them. Poisoned soil preparation: use 0.5-1.5 kg of 35% endosulfan per mu, 15 kg of soil, mix and scatter among the seedling roots; poisoned bait preparation: use 1 kg of roasted cake meal per mu, add 35 g of trichlorfon, mix well with water, scatter on the bed surface and beside the beds, in the furrows or on the ridges. Control methods for above-ground pests: the above-ground pest of Codonopsis pilosula is spider mites, generally

Detailed Explanation of Key Techniques for High-Yield Cultivation of Codonopsis pilosula
Codonopsis pilosula (poor man's ginseng) gets its name from its place of origin, "Shangdang Commandery," and is a perennial herbaceous vine of the Campanulaceae family. Its root is used as medicine. It is distributed across various provinces in the Northeast, Northwest and other regions. At present, the largest area under artificial cultivation is Weiyuan County in our province, which enjoys the reputation of "China's Hometown of Codonopsis pilosula." Pharmacological experiments have shown that Codonopsis pilosula has a blood-sugar-raising effect, can increase red blood cells and hemoglobin levels, raise blood concentration and reduce white blood cells, and also has blood-pressure-lowering and coagulation-promoting effects. Its taste is sweet, and its nature is neutral. It has the functions of tonifying qi, enriching blood and promoting fluid production. It is used for spleen deficiency, poor appetite with loose stools, fatigue of the limbs, shortness of breath and

Codonopsis stems and leaves are a high-quality feed with high nutritional value.
Codonopsis is a valuable traditional Chinese medicinal herb, with its dried roots used as medicine; it has the effects of tonifying qi and nourishing blood, harmonizing the spleen and stomach, promoting fluid production, and clearing the lungs. Its stems and leaves were often discarded in the past. However, in recent years, research has found that Codonopsis stems and leaves contain volatile oils, various amino acids, macro- and trace elements, alkaloids, starch, and more. Farmers at the Sifangpa medicinal herb farm in our county dry and crush the stems and leaves, then add them to feed at a ratio of 20-30% to feed pigs, producing a clear weight-gain effect. When used to feed poultry, not only are the egg-laying rate, egg production, and average egg weight increased, but tests also show that the cholesterol content is somewhat reduced.

Broadcasting Methods and Key Sowing Techniques for Codonopsis pilosula
First rake off the surface dry soil, use a scraper to level the bed surface, evenly broadcast the seeds over the bed surface, lightly sweep the bed surface several times with a broom, mix the seeds into the topsoil, and then compact. After sowing, cover the bed surface with 1 layer of rice straw, millet straw, corn stalks, etc., and then water appropriately, keeping the soil moist regularly to facilitate seedling emergence. Sowing rate: 15 kg per hectare for drilling, 15-20 kg per hectare for broadcasting. Codonopsis pilosula seeds are small; to sow evenly, the seeds can be mixed with an appropriate amount of fine sand before sowing. Direct

What kind of ecological environment does Codonopsis pilosula need to grow?
One-year-old Codonopsis pilosula seedlings are trailing and rarely flower. Plants more than two years old are twining and generally flower. During the growing period, it has strong adaptability to the environment. Wild Codonopsis pilosula is distributed vertically at altitudes of 1400-2100 m, growing in zones with half shade and half sun or on shady slopes, with a slope of about 15°-20°. Codonopsis pilosula is a deep-rooted plant, suitable for growing in deep, loose, well-drained sandy loam rich in humus. The soil pH should preferably be neutral or slightly acidic, generally with a pH value between 5.5 and 7.5. Codon

What are the biological characteristics of Codonopsis pilosula? A comprehensive guide
Codonopsis pilosula has strong adaptability and prefers a mild, cool climate. Its requirements for water, temperature, and sunlight differ at different growth stages. The suitable temperature for seed germination is 18-20°C. Seedlings prefer shade, while mature plants prefer light. It can tolerate high temperatures of 33°C and can also overwinter safely at -30°C. Root rot is prone to occur under poor drainage and high temperature and humidity conditions. Codonopsis pilosula is a deep-rooted plant, and the ideal soil pH is 6.5-7.0. It is not suitable for continuous cropping, and generally should be replanted after an interval of 3-4 years. The previous crop is best as legumes or grasses. Codonopsis
