摘　　要：试验结果表明,蜜蜂采集强度与饱子率呈现正相关;采集蜂数量从209只上升到326只时,向日葵的饱子率也从42.17%提高到78.77%;向日葵的饱子率与距离蜂场的远近也有明显的相关性;花盘直径大小与蜜蜂授粉次数的大小有关;在距蜂场1 300 m时,其饱子率可达64.87%以上,距离加大时饱子率则下降。为了保证向日葵的产量和质量,在向日葵种植面积占耕地面积10%左右情况下,对向日葵进行蜜蜂授粉时,蜂场之间距离不宜超过2 600 m。It is proved in this test that honeybee collection intensity and full seed rate shows a positive correlatioship. As bee quantity for collecting increase from 209 to 326, Sunflower full seed rate increases from 42.17% to 78.77%. Sunflower full seed rate and field distance from the apiary presents obvious correlationship; floral disc diameter is related with the times of bee pollination. When it is 1 300 meter apart from apiary,sunflower full seed rate reaches 64.87% ; when the distance further increases, the rate decreases. In order to ensure the quantity and quality of sunflower, when sunflower acreage accounts for 10% of cultivated land area, the distance between apiaries is better no more than 2 600 meter.
