On December 22, in the vegetable base of Qingtang Town, Dao County, farmers were setting up vegetable greenhouses. In recent years, the county has actively adjusted the structure of the agricultural industry, and through the guidance of the government and the model driven by agricultural enterprises and cooperatives, the large-scale development of the facility vegetable industry in greenhouses has promoted the increase of farmers' income and boosted rural revitalization.
