摘　　要：针对目前新疆北疆地区复播油葵存在的一些问题 ,对比了春播与复播油葵灌浆期的各项生理指标 :籽粒形成与灌浆速率 ;油分积累的变化规律 ;群体光合强度及同化物的运转 ,表明适当改善灌浆的环境条件 ,增强籽粒的灌浆活性及成油率 ,复播油葵有进一步丰产、高油的潜力。In view of the present problem that multiple cropping oil sunflower exist,we contras some physiology quota of spring sowing with that of multiple cropping oil sunflower at filling stage:taking shape and filling of seed;varying of oil accumulation;canopy appatent photosynthesis is community and conveying of assailable product,the result indicates:appropriate improve environment condition of filling stage strengthen filling active of seed and oil content,multiple cropping oil sunflower exists potentiality fitly of increaes production and oil content.
