Abstract: To explore the effects of long-term fertilization on soil property and grain yield and quality of late rice, and provide the theoretical basis for promoting the soil fertility under the goals of improving both grain yield and quality in reddish paddy field of Southern China, the long-term experiment initiated in 1982 was conducted to investigate the effects of different fertilization regimes (manure:M; chemical NPK+manure:NPKM; chemical NPK:NPK; chemical NK+manure:NKM; chemical NP+manure:NPM; chemical PK+manure:PKM; no fertilization:NF) on nutrient contents, enzyme activities, cation exchangeable capacities, grain yields and qualities in this study. The results showed that fertilization enhanced the contents of soil organic carbon and the enzyme activities of urease, acid phosphatase, sucrase and cellulase, and increased the cation exchangeable capacities, so improved the grain yields in different levels compared with NF treatment. Moreover, fertilization enhanced the percents of milled rice and head rice, increased the contents of amylose and protein, decreased the chalky grain rate and chalkiness, and lengthen the gel consistency in different degrees. Among them, balanced application of chemical N-P-K and manure had better advantages on enhancing the soil fertility and enzyme activities, which resulted in a higher grain yield and better qualities of process, appearance, flavor and nutrition. In brief, balanced use of chemical fertilizers and manure not only increased the soil properties and fertility, but also synergistically improved the grain yield and quality of rice.
