摘要
按生育期的不同将新疆北疆沿天山一带复种油葵品种分为3种生态型,分析其生育特性,结果表明:晚熟型品种在叶片生长特点、群体冠层结构及同化物运转等方面均优于早熟型及中熟型品种,但由于在灌浆中后期气温过低,造成灌浆不充分,制约其高产潜力的发挥,从而表现为低产。故鉴于当地气候条件,复播油葵应选用早熟型品种,但需采取相应的栽培措施,以利于建立合理的群体结构及提高籽粒充实程度。
The growth and development laws of different ecotypes oil sunflower according to different growing period was analyzed in North Xinjiang. The results showed that the characteristics of leaves, canopy structure and assimilate distribution index of long growth period superior to short and middle growth period. But the result of overlow temperature in the milk, not fully bring out high yield potentialities, on the contrary, shown low yield. So in view of climate in the locality might select early maturing multiple cropping oil sunflower with further improved canopy structure and plumpness of seeds.
