摘　　要：以食用向日葵品种S31为供试材料,研究不同土壤类型条件下向日葵的耗水规律。结果表明:三种土壤处理的向日葵均呈现相似的耗水动态,从苗期至现蕾期耗水量平缓上升,现蕾期至开花期耗水量迅速增加,并达到全生育期的最高值,灌浆后耗水量缓慢下降。其中沙土种植的向日葵全生育期耗水量达到4028.25m3/hm2,显著高于壤土和粘土处理;但沙土向日葵处理籽实产量较低,仅为3819.52kg/hm2,显著低于壤土处理。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.
