In view of the prominent problem that ratoon rice pattern based upon early rice is unfavorable for planting winter crops in Jianghan Plain，the study on fertilization and efficiency improvement of ratoon rice pattern based upon medium rice can provide scientific basis for improving land use efficiency.The rice variety Liangyou 1208 was used as the experimental material.Fertilization treatments were carried out for the first season rice.The application of phosphorus and potassium fertilizer without nitrogen fertilizer was taken as the control(CK)，and three application combinations of base fertilizer and top dressing were set up.The total available nutrients of each treatment were the same(N-P2O5-K2O=120-63-135 kg/hm²).Potassium fertilizer was applied as base fertilizer and panicle fertilizer with the equal amounts，and nitrogen fertilizer was applied as base fertilizer，tillering fertilizer and panicle fertilizer which had different proportions when they were applied into paddy field.The application ratio of N fertilizer as base fertilizer，tillering fertilizer and panicle fertilizer was 8∶0∶2 for CRF(controlled release fertilizer was used as base fertilizer)and 5∶3∶2 for CF(compound fertilizer was used as base fertilizer)and OCF(organic-inorganic compound fertilizer was used as basic fertilizer).The results showed that the whole growth period of Liangyou 1208 was 156～157 days.By observing leaf area index，SPAD and dry matter accumulation of rice under different fertilization treatments，it was found that compound fertilizer could promote the growth of first-season rice from its early stage to middle stage，controlled release fertilization could promote the growth of first-season rice in its late stage and the growth of ratoon rice，and organic-inorganic compound fertilizer could promote the growth of rice in regenerating season.
