The effects of applying selenium fertilizer and four different forms of phosphorus fertilizer on selenium absorption and phosphorus use efficiency of wheat were studied through field micro-region experiments.The selenium fertilizer was provided with two treatments of no selenium(SE0)and selenium(SE)，and five phosphate fertilizer treatments were set up under each selenium fertilizer treatment，namely，no phosphorus fertilizer(CK)，phosphate(AP)，ammonium polyphosphate(APP)，monoammonium phosphate(MAP)and diammonium phosphate(DAP).The results showed that: in the absence of selenium fertilizer，different forms of phosphate fertilizer promoted the absorption of selenium in wheat，but the selenium content of wheat grains did not meet the national standard of selenium-rich rice.Among them，APP treatment had the highest use efficiency of phosphate fertilizer，which increased by 2.49，4.86 and 7.07 percentage points compared with AP，MAP and DAP treatments，respectively.The selenium content of wheat grains increased significantly under the application of selenium fertilizer.Among them，the selenium content and yield of wheat treated with MAP increased by 68.11% and 56.70%，respectively，compared with CK treatment，and the use efficiency of phosphate fertilizer was increased by 16.09，15.03 and 14.86 percentage points compared with AP，APP and DAP treatment，respectively.Therefore，the combined application of selenium fertilizer and monoammonium phosphate can increase the selenium content of wheat grains，improve the use efficiency of phosphate fertilizer and yield.
