Growing environment

Low latitude and high altitude mountainous areas, is a subtropical humid monsoon climate. Less sunshine, abundant rainfall, humidity, is the most suitable area for konjac cultivation.

Konjac underground part of the bulb and longer root system, suitable for growth in deep soil, loose texture, good drainage and air permeability, organic matter-rich light sandy soil growth, the soil is loose, thick and fertile is to ensure that the konjac root growth and development and normal expansion of the tuber important conditions.

Soil pH has a greater impact on the yield of konjac, most of the konjac varieties suitable pH value of 6.5 ~ 7.0, neutral and slightly alkaline soil can be planted konjac, but the more acidic and alkaline soil is not suitable for the growth of konjac, especially acidic soil planting konjac disease is more likely to occur.
