Abstract: A questionnaire was designed to explore the cultivation status of Konjac and provide background support for the development of KGM, alkaloids and other related products in Yunnan. The results showed that the Konjac were cultivated scatteredly under the grove or grown with the corn except in Zhaotong and Fuyuan in Yunnan; that 42% cultivated variety are Amorphophallus konjac K.Koch, about 20% Amorphophallus albus P.Y. Liu & J.F. Chen; that 44.21% of the farmers plant with self-contained seed, and 36.44% farmer choose to buy Konjac seed in the market; that 50% farmers choose farmyard manure to grow Konjac; and that the soft rot infection rate of Konjac was as high as 26.72% with dry leaf disease next. At present, Konjac planting in Yunnan has begun with small scale and the investigation may provide ideas for the planning of Konjac industry and the development of Konjac products in Yunnan .
