摘 要：
This paper analyzes the status of regional disposition of chemical fertilizer resources in China, establishes production indexes for chemical fertilizer use quantity and grain crop yields at different regions, compares and analyzes the difference in yield increasing efficiency at different regions. On the basis of analysis by fixed trait and quantity, this paper provides a plan for rational disposition of chemical fertilizer at different regions, calculates the increased yields after optimum disposition, and discusses resources disposition methods within the region and their relations with grain production.
