摘　　要：对甘蓝型三系杂交油菜秋播制种技术的初步研究表明 ,采用旱、薄、瘦、密的技术 ,结合其它农艺措施 ,能有效地减少微粉的发生 ,使杂种不育株率降低 4 %～ 9% ,从而提高种子纯度 。The autumn sowing measures in seed production of ternary hybrid rape (B.napus) for raising its seed purity were carried out. The results showed that taking the technical way of limiting water and for tiliger, close planting, integrating with other agronomical measures, the occursouce of micropollen can be reduced effectively, so as to decreas the sterile rate of the hybrid population by 4%～9% and to overcome the risk in seed production centainly.
