Natural rubber had excellent comprehensive properties and wide applications. However，differences in rubber properties were caused by differences in rubber tree varieties，climate and management systems. Fertilization was one of the important factors affecting the properties of rubber. It was of great significance to study the effects of different fertilization measures on the properties of raw natural rubber for guiding production. In this study，mature rubber trees were selected，no fertilization control and four different fertilization measures were set up，including nitrogen phosphorus potassium fertilizer，organic fertilizer，nitrogen phosphorus potassium fertilizer+organic fertilizer，nitrogen phosphorus potassium fertilizer+organic fertilizer+magnesium zinc boron fertilizer，and the effects of different fertilization measures on the properties of raw rubber of natural rubber were discussed to provide reference for actual production. The results showed that the nitrogen content (12%)，plastic retention rate (7%) and plasticity of the raw rubber could be increased by the four fertilization measures；nitrogen phosphorus potassium fertilizer reduced the Mooney viscosity (17%) and improved the plasticity of raw rubber at the early stage of fertilization；The Mooney viscosity of organic fertilizer at the early stage of fertilization was 26% higher than that of the control，which increased the molecular weight of raw rubber；nitrogen phosphorus potassium fertilizer+organic fertilizer was beneficial to maintain the stability of nitrogen content and impurity content；nitrogen phosphorus potassium fertilizer+organic fertilizer+magnesium zinc boron fertilizer treatment was conducive to maintaining the consistency of nitrogen content，volatile content，ash content and plastic initial value of raw rubber. To sum up，among the four fertilization measures，the organic fertilizer treatment and the nitrogen phosphorus potassium fertilizer+organic fertilizer are better，followed by nitrogen phosphorus potassium fertilizer，and nitrogen phosphorus potassium fertilizer+organic fertilizer+magnesium zinc boron fertilizer are worse.
