In order to definite the optimal phosphorus application for different available phosphorus content area and improve phosphate productivity, it conducts field plot contrast experiments using Yanfeng 47 as the material to study the effect of different phosphorus application on rice yield and phosphorus using efficiency during the Xinjian base which available phosphorus content is relatively lower and the Xi'an farm which available phosphorus content is relatively richer. The main results are as follows. Through the path analysis of yield components, it was concluded that the number of spikelet contributed the most to the yield. The reasonable phosphorus application should be pursued the high number of spikelets in the population and the enrichment of storage capacity. With the increase of phosphorus application, the phosphorus using efficiency and productivity of phosphate fertilizer decreased in the range of 105-210 kg/ha. With the advance of the growth process, the phosphorus uptake gradually increased, among which the phosphorus absorption ratio was the highest from the jointing stage to the full heading stage.
