ABSTRACT
At the beginning of 2008, the southern regions of China were affected by particularly cold weather. The frost caused considerable loss of the konjac grown in Hubei, Shanxi, and Chongqing, which reduced the konjac planting area to 1.02 million mu (15 mu = 1 ha) in that year. The planting area returned to its original size in three years. The size of subsequent planting areas has expanded rapidly since then (see Table 9.1). Planting Area of Konjac from 2008 to 2017 (unit: 10,000 mu)
