What kind of environmental conditions does Codonopsis pilosula cultivation require?
Codonopsis pilosula is also known as three-leaf vegetable, single leaf, and stinking codonopsis. It is a perennial climbing herbaceous plant of the Campanulaceae family. Codonopsis pilosula is a commonly used traditional Chinese medicine, originally from Shangdang, Shanxi; its root resembles ginseng, hence the name codonopsis. The root is used medicinally and has the functions of tonifying qi and nourishing blood, harmonizing the spleen and stomach, promoting fluid production and clearing the lungs. There are many varieties of codonopsis medicinal material, such as Western codonopsis, mainly produced in Gansu, Shanxi, Sichuan and other provinces; Eastern codonopsis, mainly produced in the northeastern provinces; Lu codonopsis, mainly produced in Shanxi, Henan and other provinces. The Tai codonopsis among the Western codonopsis is especially the best in quality. Codonopsis is a deep-rooted plant that prefers a cool and moist climate.

Symptom Identification and Control Methods of Root Rot in Codonopsis pilosula
The pathogen is a type of imperfect fungus among the fungi, and it is divided into two types: chronic onset and acute onset. In the chronic type, the disease begins in mid to late May. In the early stage of the disease, dark purple lesions appear on the lower fibrous roots or lateral roots, which then turn black and rot. After the disease spreads to the main root, it gradually rots from bottom to top. The remaining unrotted part is mostly a "half-section ginseng," and the area near the rotted part is dark brown. The stems and leaves above ground gradually turn yellow and eventually die. In the acute type, the disease mostly begins in mid to late June. Once the ginseng root is infected, almost the entire ginseng root becomes diseased at the same time

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

Control Methods and Key Technical Points for Codonopsis Diseases
I. Rust mainly damages the stems and leaves of Codonopsis. Control methods: clean the field, eliminate field weeds and diseased plants. In the early stage of the disease, spray 25% triadimefon wettable powder at 1000-1500 times dilution, or 90% dithianon sodium at 400 times dilution for control. Spray once every 7-10 days, for 2-3 consecutive sprays. II. Root rot mainly damages the roots of Codonopsis. Control methods: from July to August, apply additional phosphorus and potassium fertilizer. Before transplanting Codonopsis, soak the roots in 50% thiophanate-methyl wettable powder at 1000 times dilution for 5 minutes. When the disease occurs
