摘　　要：利用1994-2003年10a的土壤水分观测资料,分析向日葵全生育期间土壤水分含量变化规律,发现河套灌区向日葵全生育期间,有三个土壤湿度低值时段,分别处于向日葵出苗后30d、现蕾开花期、灌浆期。为此,根据上述结论和当地向日葵浇水习惯,设计了不同浇水时段进行了田间浇水试验。通过正交直观分析,结果表明,油用向日葵在出苗后30d、现蕾期、开花期浇水较为适宜;食用向日葵在出苗后30d、现蕾期、开花期、灌浆期浇水较为适宜。并根据不同生产实际情况提出了不同的生产建议,为向日葵发展提供参考。By analyzing the change rules of the soil moisture content of sunflower in whole growth period using ten years observation data of soil moisture,it showed that there were three low value stages of soil moisture at 30 days after seedling emergence,flower bug stage,and filling stage in the whole growth period in Hetao irrigation area.Therefore,according to the conclusion and the local watering habit,it designed field watering experiment at different time.Using the orthogonal analysis,the results showed that it is suitable for watering oil sunflower at 30 days after seedling emergence,flower bud,flowering stage and the edible sunflower at 30 days after seedling emergence,flower bud,flowering stage,filling stage.On the basis of different actual production condition,it provided different production suggestion for the development of the sunflower.
