Abstract: The results indicated that foliar spraying of Increase Production Reagent with Selenium-Abundant (IPRSA) on green rice could markedly increase their grain numbers, grain weight, contents of Selenium in grain and yield of grain, and evidently increase agricultural efficiency，which demonstrated that this strategy was worth popularizing and application. The best yield-enhancing results would be achieved by foliar spraying with 150 gram of IPRSA per 667 m2 at the stage of heading spike.
