研究了首次打顶时间为现蕾当天、现蕾后第5天、第10天、第15天、第20天（第2次打顶时间在首次打顶后7 d,共打顶2次）5个处理对亚麻抗倒及产量品质的影响。结果表明：从现蕾当天到现蕾后20 d,随打顶时间推移,田间倒伏率相应增加,从4.5%上升到26.5%,麻株直立株率从90.5%减少到65.5%;株高和工艺长度从70.5 cm增加到80.5 cm,而茎粗从0.262 cm减少到0.240 cm;原茎产量除现蕾后5和10 d打顶处理减幅（4.45%～5.64%）不明显外,其他处理较对照均显著减少;打顶处理后亚麻纤维品质都有所改善,单纤维强力增强19.72%～34.25%,纤维分裂度增长2.24%～5.88%;从田间倒伏和产量品质综合考虑,亚麻生育后期以现蕾后5...

Effect of five decapitation treatment of the first topping time for the bud of the day,after squaring 5 d,10 d,15 d,20 d were studied on flax anti-lodging,yield and quality.The results showed that from the budding stage to the day after budding 20 d,with the topping over time,the field lodging rate increased from 4.5% to 26.5% and lodging degree aggravated appropriately,while its vertical hemp plants reduced from 90.5% to 65.5%;its height and process length increased from 70.5 cm to 80.5 cm and stem diameter decreased from 0.262 cm to 0.240 cm....
