What are the growing conditions for Pinellia ternata? A detailed explanation of its environmental requirements
Pinellia ternata, also known as Diwen and Shoutian, is a herbaceous plant of the genus Pinellia and a relatively common Chinese medicinal herb, with effects of relieving cough and resolving phlegm, and stopping vomiting and inducing vomiting. In recent years, with the destruction of wild environments and the extensive use of herbicides, wild Pinellia ternata resources have become increasingly scarce, so artificial cultivation has emerged. However, Pinellia ternata has strict requirements for the growing environment. Let us take a look below at the growing conditions for Pinellia ternata.
1. Soil requirements
Pinellia ternata is not strict about growing requirements, and can be planted in any soil except saline-alkali land, gravel soil and heavy clay, but for planting, deep soil layers, loose and fertile soil, and moist sandy loam are preferable. Pinellia ternata is not tolerant of saline-alkali conditions, so a soil pH of 6-7 is suitable. Pinellia ternata can be continuously cropped, but the continuous cropping period should not be too long; generally it should be rotated once every 3-4 years to avoid worsening pest and disease damage. The previous crop is best as beans, wheat and similar crops.
2. Temperature requirements
As can be heard from its name, Pinellia ternata is harvested in summer and autumn, so before planting it is generally in February to April, when the temperature is moist and suitable for its growth. Its seeds begin to sprout at 8-10 degrees, with the most suitable temperature between 20-25 degrees. Once the temperature exceeds 30 degrees, growth slows, and above 35 degrees it causes, while below 13 degrees growth is affected. Its underground tubers have strong cold resistance and can overwinter normally at temperatures below 0 degrees.
3. Light requirements
Pinellia ternata is shade-tolerant but does not like shade. Under appropriate shading conditions, it can grow luxuriantly, while with too much shading, growth is weaker. In addition, light intensity is also related to the growth and development of its bulbils and the quality of its tubers. If the light is too strong, it will cause death and make survival difficult. The best light condition is semi-shade, as only then will the yield be higher.
4. Water
Pinellia ternata likes moist and damp environments and is not tolerant of drought, having relatively high water requirements, but because it is a shallow-rooted crop, its absorption capacity is limited, and the aboveground plants have poor drought tolerance. Therefore, when planting, it must be watered frequently to keep the soil moist, but watering should not be excessive. It likes water and also fears water. If watered too much and water accumulates, it will instead grow poorly, and in severe cases cause root rot and root rot, and seedlings are very likely to die, affecting yield. Therefore, when planting, drainage and waterlogging prevention measures must be strengthened, especially in the rainy season.
