不同抑芽剂对亚麻开花期打顶后腋芽生长及防倒效果的影响

为有效控制亚麻生育后期打顶后腋芽生长,提高亚麻抗倒伏能力,选用生产上常用的抑芽剂(30.2%芽畏乳油,25%芽克水剂,25%抑芽敏乳油,33%除芽通乳油)进行了田间抑芽和防倒试验。结果表明,4种抑芽剂均具有一定抑芽效果,且处理后防倒效果明显,原茎产量都有所减少,而工艺产量明显增加;以除芽通和抑芽敏的抑芽效果较好,至工艺成熟期抑芽率均高于70%;防倒效果、工艺产量及纤维品质都以抑芽敏处理效果最佳,与常规栽培亚麻相比,其倒伏率减少81.60%、工艺产量增加23.68%,纤维强力增强20.56%。

Effect of Different Sucker Controlling Agents on Axillary Bud Growth and Anti-lodging at Flowering Stage After Topping in Flax

To effectively control the axillary bud growth and enhance anti-lodging capacity after topping in flax,four kinds of sucker controlling agents(30.2% yawei EC,25% yake SL,25% yiyamin EC,33% chuyatong EC) were used on field experiment for inhibiting sucker and anti-lodging in flax.The results showed:four kinds of sucker controlling agents had more or less inhibiting effect and its anti-lodging effect was evident after treated;The agrinomy yield reduced and craft yield increased respectively;Yiyamin and chuyat...
