| Abstract: | A experiment of the effects of fertilizer application on water use efficiency(WUE) of sunflower were conducted in Heyang. Shaanxi Province. semihumid area liable to drought. The result showed that the WUE of sunflower increased with the amount of fertilizer applied within a certain range of fertilizer application. The WUE of sunflower increasement were 13. 6% ~ 45. 3%. It was a important way to improve the WUE and yield of sunflower that using the technique of rational fertilizer application in sermihumid area liable to drought. |
