To solve the general problems in difficult seed selection and blind fertilization in corn planting,based on soils data accumulated in the past years,our experience on corn's popularization and demonstration,and relied on the theory of balance method of soil nutrient and the technique of effective corrective factor of soil nutrient,we developed the technical advisory service system for corn planting to guide seed scientifical selection and accurate fertilization.The system has the advantage of good pertinency,strong practical,and prominent regional.It could recommend high productive and efficient seed on the basis of field's natural conditions and calculate precise fertilization rate using target output method.The result indicated that the system will reduce fertilizer input costs effectively and enhance economic returns.
