摘　　要：进行了矮壮素在夏秋大棵小白菜栽培中的应用研究试验。试验结果表明,在小白菜播种后20 d,喷施浓度为300 mg/L的矮壮素,叶片质量/叶柄质量最高为0.68,比CK(喷清水)提高0.11,各营养成分优于CK;株高比CK下降6.1 cm,株型紧凑美观;产量达1 845.4 kg/667 m2,比CK增产24.8%。In this paper, we studied the application effect of chlormequat on cabbage cultivation in summer and autumn. The results showed that spraying chlormequat with the concentration of 300 mg/L after 20 days of sowing, the ratio of leaf weight to leaf stalk weight was 0.68, which was 0.11 higher than that of control, and the cabbages＂ nutritional quality was better than that of control. The plant height was decreased by 6.1 cm than that of control, and the plant was compact. The yield was 1 845.4 kg/667 ㎡, which was 24.8% higher than that of control.
