| Abstract: | The study was conducted to seek a way for obtaining high yield of oilseed rape and to promote the use of nitrogen and phosphorus.In this article,1%(mass fraction) KCl solution was sprayed to the stems and leaves at the fully blooming stage of the crop with spraying 1.17%(mass fraction)K2SO4 solution and clear water for the control.Plant samples were taken at initial siliquing and harvesting stages,soil culture used in this experiment.Results showed that,the average of NRA was increased by 26.9% under the KC... |
