| 摘 要： | 在干旱半干旱地区将有限的水资源充分利用在向日葵对水分最敏感的时期——现蕾期（灌水150．0m^3／hm^2），产量比不补灌水增加866．70kg／hm^2，增长60．74％，降水利用率提高16．4％，水分生产效率提高4．05kg／（mm·hm^2），水分生产效益提高17．25元／（mm·hm^2）。

| Abstract: | The limited water resources in arid and semi-arid regions were fully used in the most sensitive period （budding stage） of sunflower to water （irrigating 150.0 m3/hm^2）, so that the yield was increased by 866.70 kg/hm^2 than non-supplemental irrigation, with increase rate of 60.74%; precipitation utilization rate was increased by 16.4%; water production efficiency was increased by 4.05 kg/（mm·hm^2）, and water production effectiveness was increased by 17.25 yuan/（mm·hm^2）. |
