Abstract: Study on water consumption of sunflower in different type＇s soil in Loop,used edible sunflower varieties S31 as materials.The results showed that： three soil treatments showed a similar water dynamics,water consumption increased slowly from seedling to budding stage,increased rapidly from budding stage to flowering and reached the highest value of the whole growth period,and slow decline after the grouting.Water consumption reaches 4028.25m3/hm2 in the whole growth period when sunflower planted sand,significantly higher than that of loam and clay treatments,but lower seed production,only 3819.52kg/hm2,significantly lower than the loam soil treatment.
