Abstract
The fertilization research on maize in high yield field indicates:the decrease of 40% fertilizer application amount and maximum increase to 44.30% for N use efficiency with optimizing use of fertilizer (P,K added as base fertilizer,N lowered as dressing),compared with the habitually application of fertilizer under the premise of keeping same yield,which result in reasonable exploitation of the nutrient resources,economizing cost,lower remaining soil nitrate quantity,environmental protection, and sustainable development.
