Abstract: In order to investigate nitrogen utilization rate，application technology and fertilizer value of slow-release fertilizer，wheat was taken as experimental object，and effect of new slow release fertilizer on crops was discussed.Results showed that after application of new slow release fertilizer，utilization rate of nitrogen was further improved，quality of crops was improved，and loss of nitrogen leaching and environmental pollution were reduced.Quality of wheat was better after using new environmental protection slow release fertilizer.Compared with traditional way of fertilization，effect of new environment friendly slow release fertilizer on different growth stages of wheat was better，which could meet demand of yield and ensure social and economic benefits.
