In this study the systematic approach for soil nutrient status evaluation(ASI) was used to test soil and recommend fertilizer rates for rice,and then plot experiments were carried out to validate the effect of the optimal phosphorus and potassium application rates on rice yield component.The results showed that at the optimal fertilization rates of other nutrients,the number of effective tiller,heavy kernel,thousand grain weight and yield of rice were the best at the optimal fertilization rates of phosphorus and potassium(P2O5 90 kg/hm2,K2O 105 kg/hm2) recommended by ASI,and applying phosphorus fertilizer could significantly increase the number of effective tiller(p<0.01),and applying potassium fertilizer could significantly increase the number of heavy kernel and thousand grain weigh,and at last achieve the high yield object.So that using ASI soil testing and fertilizer recommend method for rice in the marine foreland is greatly feasible.
