1. Soil: Konjac needs deep soil layer, loose and fertile soil, rich in organic matter and humus, and neutral and acidic sandy loam. The optimum pH value is 6.5~7.5, and it can grow at pH5.5~6.5 or pH7.5~8.

2. Humidity: Amorphophallus konjac needs good soil drainage, low groundwater level, loam water content of 50-65 mass, air relative humidity of 55-70 and rainfall of 1 0,000-1500 mm..

3. Temperature: The growth cycle of Amorphophallus konjac needs an appropriate temperature of 15~25℃, the growth above 35℃ is inhibited, the buds below 12℃ naturally emerge from the aboveground parts, and the underground tubers below -8℃ can resist freezing injury during dormancy.

4. Illumination: Amorphophallus konjac is a shade-tolerant crop and is most afraid of direct sunlight. It requires weak light intensity and short time. The optimum light intensity for aboveground part development is 1/3 sunlight, and the root system development needs dark light.
