摘　　要：羽衣甘蓝经过春化后温度升高时即可抽薹开花,即使剪去花茎也会影响到其观赏效果。为抑制羽衣甘蓝抽薹,延长植株观赏期,需要筛选适宜的生长调节剂喷施方案,通过在羽衣甘蓝不同生长时期喷施不同浓度的比久(B9)、多效唑(PP333)、矮壮素(CCC)、青鲜素(MH)等生长调节剂,对比分析喷施处理后羽衣甘蓝的抽薹数量、花薹高度、开花及观赏性等情况。结果表明:在薹高0.5 cm左右喷施3000~4000 mg/L MH可起到显著抑制抽薹开花的效果,但对于叶片色彩艳丽的品种,喷施MH后会使转色叶片褪色而降低观赏性。When the temperature rises after vernalization stage,kale can bolt and blossom,even if the flower stem is cut off,the ornamental effect will be affected.In order to inhibit bolting and prolong the ornamental period of kale and screen out suitable spraying schemes of growth regulators,daminozide(B9),paclobutrazol(PP333),chlorocholine chloride(CCC)and maleic hydrazide(MH)were sprayed at different growth stages of kale.The number of bolting,height of flower bolt,flowering and ornamental properties were compared and analyzed after spraying.The results showed that spraying MH 3000-4000 mg/L on 0.5 cm bolt height stage could significantly inhibit bolting and flowering,but for cultivars with bright colors,the color leaves would fade to a certain extent after spraying and the ornamental value would be reduced.
