The meeting was chaired by the Science and Technology Commission of Mianyang. Dioseorea zingiberensis Wright is a wild perennial twining herb. Dimethoads (diosgenin) is an important raw material for synergistic or contraceptives and stays in the rhizome. The increase in the amount of drugs required can supplement the deficiency of yam resources. The meeting heard a technical report on the agricultural cultivation of D. zingiberensis from the Chengdu Institute of Biology, Chinese Academy of Sciences. After two years of cultivation, the site was excavated and harvested.
