摘要
以油菜品种甘杂 1号为材料 ,研究应用BN - 3、BN - 4调节剂对促进油菜生长发育的作用。结果表明 :喷施BN使油菜生育期提前 1～ 2d ,增加角果面积 2 2 .99～ 32 4 .6 0cm2 /株 ,增加角果 0 .6～ 2 5 .5个 /株 ,每角粒数增加 0 .9～ 2 .4粒 ,千粒重提高 0 .0 5～ 0 .2 0g ,比不施用BN对照增加产量 12 .2 %～ 14 .7%。以抽薹期BN - 36mg/kg和始花期BN - 36～
The effect of BN-regulators on rape growth and development for variety of Ganza No.1 was investigated. The result showed that growth period of rape decresed 1～2 days, pod area per plant increased 22.99 ～324.60cm 2, number of pod per plant increased 0.6～25.5, number of seeds per pod increased 0.9～2.4, 1000 seeds weight increased 0.05～0.20g, yield outyielded the control treatment by 12.2%～14.7% under BN applied condition. The better concentration of BN-3 applied in rape was 6mg/kg at bolting stage and 6～8 mg/kg at first flowering stage.
