摘　　要：试验针对甘蓝未熟抽薹现象,通过对京丰1号甘蓝6~7片真叶期、12片真叶期2个阶段进行爱多收、矮壮素、比久、多效唑4种生长调节剂不同浓度的处理,结果表明,在6~7片真叶期喷施4500mg/L的比久,抗抽薹能力最强,抽薹率为6.25%,比喷清水低50.4个百分点。12片真叶期喷施植物生长调节剂效果不是很理想。The immature-bolting in Cabbage causes great yield reduction, the following experiment was performed to test the effect of plant growth-regulator on overcoming the immature-bolting. Cabbage variety Jingfeng No.1 was used in the experiment, four kinds of plant growth-regulators, including ATONIK, CCC, B9, PP333, were sprayed with different concentration during seedling stage （6-7 and 12 main leaves）. The results showed that the spraying of 4 500 mg/L of B9 at stage 6-7 leaves had the best effect on anti-to resist immature-bolting, its bolting-rate was only 6.25%.
