Effects of totally basal dressing technique (F1 and F2,for early rice and late rice respectively) to whole plough layer on double harvest rice and traditional fertilization(CK1 and CK2,for early rice and late rice respectively) were compared by 15 N and 32 P tracing techniques under field conditions.There were no differences in total absorption of nitrogen and phosphate by rice plant,accumulation of biomass, 15 N utilization rate, 15 N recoverable rate and even in the yield between F1 and CK1,F2 and CK2 respectively.However,the tech...
