Which regions are the latest production areas of Paris polyphylla?

Paris polyphylla is also known as Qiyeyizhihua, Hua Chonglou, Qiyelian, Tiedengtai, etc. It is the dried rhizome of Paris polyphylla var. yunnanensis or Paris polyphylla of the Liliaceae family, Paris genus, and is a precious Chinese medicinal herb with effects of clearing heat and detoxifying, reducing swelling and relieving pain, and cooling the liver to calm fright. Now let us take a look at the production area distribution of Paris polyphylla!

Production Area Distribution of Paris polyphylla

The production areas of Paris polyphylla var. yunnanensis are mainly distributed in Yunnan, Guizhou, Sichuan and other places, while the production areas of Paris polyphylla are mainly distributed in Guangdong, Guangxi, Jiangxi, Fujian, Shaanxi, Sichuan and other places.

Production Environment of Paris polyphylla

1. Soil: Paris polyphylla grows best in well-drained slightly acidic humus soil or fertile sandy soil. It cannot grow in alkaline soil or clay soil, and soil that is sticky, prone to water accumulation and hardened is not suitable for growth.

2. Moisture: Paris polyphylla prefers a cool, shady and moist environment with moderate moisture. It is afraid of both drought and water accumulation. If the soil moisture content is too low, it easily causes the stems and leaves to lose water and the root system to dry up and die, while if it is too high, pests and diseases are likely to occur and the rhizome will rot.

3. Temperature: Paris polyphylla plants are relatively cold-tolerant and suffer no frost damage at low temperatures. From late February to early March, when the temperature is 5°C, or even at a minimum temperature of 2°C, they can still sprout and grow. When the temperature is 1-2°C, no frost damage occurs to the buds. Generally, the suitable temperature for seed germination, root growth and development, and terminal bud germination is 18°C-20°C, for seedling emergence it is 20°C, for aboveground plant growth it is 16°C-20°C, and for underground rhizome growth it is 14°C-18°C.

4. Light: Paris polyphylla is a shade-loving plant that prefers oblique or diffused light and avoids direct strong light. Its growth requires a shaded environment, as stronger light will cause the leaves to wither. Generally, during the seed germination and seedling stages, better shading is required, while two years before maturity, shading should be appropriately reduced and light increased, which is beneficial to the accumulation of secondary metabolites and dry matter.
