摘要： 文章研究了食用向日葵杂交种、常规种在不同生长时期施用不同硼肥对产量因素的影响。结果表明：不同硼肥处理对食用向日葵产量、千粒重、结实率增效明显；不同硼肥处理对食用向日葵常规种的产量、千粒重、结实率增效更显著；不同硼肥处理对食用向日葵产量的增加是通过增加其千粒重、结实率来实现的。

Abstract: In this paper,we fertilized different boric fertilizer to the edible sunflower hybrid and the conventional breed in the different growing periods in order to study the effect of boric fertilizer to the edible sunflower output factors.The results showed that different treatment of boric fertilizer increased the edible sunflower output,the thousand grain weight and the setting percentage significantly.The increasing effect of different treatment of boric fertilizer to the edible sunflower conventional breed output,the thousand grain weight and the setting percentage was more remarkable.And the different treatment of boric fertilizer to the edible sunflower increased the thousand grain weight and the setting percentage firstly,then it caused the output increasement.

Key words: Edible sunflower, Boric fertilizer, Hybrid breed, Conventional breed, Output, Thousand grain weight, Setting percentage significantly
