Recently,in Xujing Poverty Alleviation Industrial Park of Feidong County,Liao Huajun,a potato expert from the Provincial Academy of Agricultural Sciences,constantly wandering around the planting bases,patiently explaining potato planting techniques to the farmers: "In the early stage of seedling,promoting roots and stolons should be the first thing.After coming out to 7 to 8 true leaves,the seedling growth is slow and temperature is low,it should be more tillage and less irrigation for the water demand is little." 
In 2020,the Provincial Academy of Agricultural Sciences and Feidong County Agricultural Technology Center set up the chief expert studio in the industrial park,based on the development of potato industry,to carry out technical assistance.Under the technical guidance of the expert studio,the production of potato increased vigorously.Due to the advanced technology and good varieties,the potato yield per mu came up to more than 2000 kilograms,and had good image and quality,the market demand exceeds supply,driving potato planting area of the industrial park increased year by year.
