Yinan County is located in the central Yimeng Mountain, perennial perennial planting area of 210000 acres. In the past, because cultivation techniques were not matched, peanut mu production never exceeded 200 kilograms. 1987 Provincial Science and Technology Commission decided in winter Science and Technology Poverty Alleviation project, in Yinan County peanut good law supporting cultivation technology development test, by the provincial peanut and Yinan County Bureau of Agriculture to share.

Through technological development, the development zone will be transformed from low-yielding to medium-yielding and further high-yielding so that peasants can get out of their poverty as soon as possible. Development plan requirements, 1988-1990 King County Township development test base, the township in the first three years average yield of 204 kilograms, based on the 1.35 hectares of peanut mu annual increase of 20 kilograms, three years cumulative increase of 60 kilograms.
