油菜摘薹是一项行之有效的增产措施。一是能使植株变矮、节间缩短、分校增多、角果增大、籽粒增加,通常比不摘薹的单株增加有效分枝4或5个,增加角果30个左右。每个角果增加菜籽2或3粒。平均667平方米可增产10％～13.5％。二是促进植株生长整齐、花期集中、成熟提早。一般比不摘薹的全生育期缩短4～5天。三是能显著提高植株抗逆性,特别是抗倒伏能力和抗病能力。 油菜摘薹应掌握摘早不摘晚、摘壮不摘弱、摘肥不摘 Rapeseed rapeseed is an effective stimulation measures. First, it can shorten the plant, internode shortening, increased branch, increased angle fruit, grain increases, usually than the bolting of trees to increase the effective number of branches 4 or 5, increase the pod 30 or so. Add 2 or 3 seeds of rapeseed per horn. An average of 667 square meters can increase 10% to 13.5%. Second, to promote plant growth and tidy, flowering focus, mature earlier. Generally shorter than the whole growth period without picking shortened 4 to 5 days. Third, can significantly improve plant stress resistance, especially lodging resistance and disease resistance. Rape picking should grasp the early pick up the evening, picking Zhuang not weaken, picking pick not pick
