Abstract:

Effect of different fertilizer treatments on rice yield , quality ,amylogram properties and protein fraction content of rice grain are researched. under the field experiment for rice variety Jinyuan45. The result showed that rice yield applying 4 different fertilizer treatments was 20.42%-56.94% higher than that of control. The highest yield were obtained by applying the treatment Ⅱ；The treatment Ⅳ obtained the lowest yield.； The grain yield of the treatment Ⅲ and Ⅴ was lower than that of the treatment Ⅱ. The amylose content was significantly different and protein content was not significantly between different treatment. The highest breakdown, lowest setback and the best tasted value was obtained by applying the treatment Ⅳ,while the lowest breakdown, highest setback and the worst tasted value was obtained by applying the treatment Ⅱ. All four protein fractions had not significant correlation with the tasted value of rice grain, porlamin was negatively correlated with peak viscosity and final viscosity, glutenin was negatively correlated with peak viscosity, other protein fractions content had not significant correlation with all indexes of RVA profile. The treatment Ⅲ and Ⅴwere good methods of applying fertilizer because they both obtained higher yield and better eating quality.
