Temperature requirements of Pinellia ternata

Pinellia ternata needs more than 10 ℃ ground temperature for germination and emergence, and the optimum growth temperature is about 20 ℃. When the temperature exceeds 35 ℃, the aboveground part of Pinellia ternata growing in the open without shade will wilt and die, resulting in a large area of lodging of Pinellia ternata seedlings; When the temperature is lower than 5 ℃, the growth of Pinellia ternata stagnates. When it is lower than 0 ℃, pay attention to prevent frostbite

Humidity requirements of Pinellia ternata

Pinellia ternata is not drought tolerant and likes humidity. The soil with high humidity is suitable for its growth. Irrigation with well water once in the summer evening can keep the soil moist on the one hand and reduce the soil temperature on the other hand. Of course, watering should also be moderate. Pinellia ternata likes water and is afraid of water. There should be no ponding, because ponding will cause poor plant growth, rotten roots, rotten stems and dead seedlings under anoxic conditions, which will eventually lead to the decline of tuber yield

Light requirements of Pinellia ternata

Pinellia ternata is a shade tolerant plant and is afraid of strong light. If the light is too strong, it will burn the leaves of Pinellia ternata, which is easy to cause plant wilting; If the light is too weak, it is easy to cause weak stems and inverted seedlings. Therefore, Pinellia ternata should grow in a semi shady environment, and can grow and flourish under moderate shading conditions

Soil requirements of Pinellia ternata

Pinellia ternata has shallow roots, and the moist, fertile and deep soil is suitable for its growth. Generally, the soil requirements are not strict. Except that the saline alkali soil and over sticky soil are not suitable for planting Pinellia ternata, other soils can basically grow, but the general soil moisture content is 25%, and the loose and fertile neutral sandy soil is the best

Fertilizer requirements of Pinellia ternata

Water and fertilizer management is the premise of increasing the yield of Pinellia ternata. Before planting, base fertilizers such as bean cake fertilizer and stable manure can be mixed in the soil to ensure sufficient nutrient supply in the early stage of growth. After the plant enters the prosperous period, pay attention to Topdressing and pour liquid fertilizer, which is conducive to keeping the soil moist on the one hand and promoting the growth of Pinellia ternata on the other hand, so as to increase the yield
