摘　　要：试验采用不同浓度的比久(B9)溶液叶面喷施盆栽羽衣甘蓝,研究对其生长调控的作用。结果表明:1 0～1 5g LB9处理可使盆栽羽衣甘蓝株形矮化,叶片增厚,叶面积减小,叶色加深,叶片的着色延迟,观赏价值提高。Plant growth regulators (PGR)are often used to control plant growth. The excessive growth of Kale takes place because of high temperature and humidity in summer, making its quality decrease. The potted Kales were treated with daminozide (B_9) of different concentrations by foliage spraying. The results showed that the treatments of 1.0～1.5 g/L B_9 are effective in reducing the height of the potted Kale, increasing the thickness of leaves, reducing the area of leaf, increasing the content of chlorophyll, darkening the leaf color and delaying coloring, and effectively improve the appreciation value of the potted Kale.
