Title: Effects of Different Fertilization Models on Rice Yield and Soil Organic Carbon Content in a Long Period in Red Soil Paddy Field
Abstract: The yield potential of double cropping rice was investigated after 31-year fertilization treatments at the same application rates of nitrogen(N),phosphorus(P),and potassium(K)in the from of in organic manure and chemical fertilizer(NPK)in the Red Soil Field Experimental Station,Chinese Acadamy of Agricultural Sciences,in 2012.Fertilizer application promoted rice yield and total rice aboveground biomass,increased soil organic carbon content,with combined application of organic fertilizer and chemical fertilizer being better.Combined application of organic fertilizer and chemical fertilizer showed a better yield-and aboveground biomass-promoting effect,and application of organic fertilizer has the stepwise larger effect on rice yield and above-ground biomass and has the obvious larger effect on soil organic carbon content than application of chemical fertilizer.
