Huangsongdian has accelerated the industrialization process of edible black fungus cultivation in recent years. One national-level standardized cultivation demonstration park as well as two provincial-level demonstration parks and 29 industrial parks have been built. As the scale of cultivation grows, local authorities cooperate with universities and science institutes to carry out lectures about cultivation technology and sales knowledge. The edible black fungus cultivation industry has accounted for more than 90 percent of the whole farmers' income in Huangsongdian. (Xinhua/Zhang Nan)
