In recent years, with the destruction of wild environment and the use of herbicides, wild Pinellia resources are becoming more and more scarce, so artificial cultivation has arisen. However, Pinellia ternata is strict with the planting environment. Let's take a look at the planting conditions of Pinellia ternata.

1. Soil requirements

Pinellia ternata is not strict with planting requirements. It can be planted in soil except saline-alkali land, gravel soil and heavy clay soil. However, it is appropriate to plant Pinellia ternata in sandy loam with deep soil layer, loose fertile soil and wet soil. Pinellia ternata is not tolerant to saline-alkali, so the pH value of soil is appropriate at 6-7. Pinellia ternata can be continuous cropping, but the continuous cropping time should not be too long. Generally, it should be rotated once every 3-4 years to avoid aggravation of pest damage. The previous crop is preferably beans, wheat and other crops.

2. Temperature requirements

Pinellia ternata can be heard from its name. It is picked in summer and autumn, so it is generally planted in February-April, when the temperature is humid and suitable for its growth. Its seeds begin to germinate at 8-10 degrees Celsius, the most suitable temperature is between 20-25 degrees Celsius, once the temperature exceeds 30 degrees, it will grow slowly, more than 35 degrees will cause, and the temperature below 13 degrees will affect growth. Its low tuber cold resistance is strong, can be in 0 degrees below the temperature of normal winter.

3, lighting requirements

Pinellia ternata is shade-tolerant but does not like shade. It can grow luxuriantly under proper shading conditions, but it grows weakly under too much shading. In addition, the intensity of light is also related to the growth and development of its bulbils and the quality of tubers. If the light is too strong, it will cause death and it is difficult to survive. The best light condition is half shade, so that the yield will be higher.

4. Water

Pinellia ternata likes wet and humid environment, does not tolerate drought, and has higher requirements for water, but because it is a shallow root system, its absorption capacity is limited, and the drought tolerance of the above-ground plants is poor. Therefore, it must be watered frequently when planting to keep the soil moist, but it should not be watered too much. It likes water and is afraid of water. If it is watered too much, it will grow poorly. In serious cases, it will lead to rotten roots and rotten roots. The seedlings are easy to die and affect the yield. Therefore, drainage and waterlogging prevention measures must be strengthened during planting, especially in rainy season.
