花椰菜是十字花科植物,它的花球是人们喜爱的蔬菜之一。为此,我们用赤霉素试验,探讨花椰菜提早结球、提高产量的方法。 试验品种是日本雪山花椰菜,赤霉素浓度为50、100、150ppm、清水对照。共四个小区三次重复。处理时期为小苗长出4叶一心时,用以上浓度的赤霉素喷施叶面,经2周后调查发现50、100ppm的赤霉素对花椰菜花球的形成具有促进作用,以50ppm处理的效果最好,比对照组提早7天左右现球,并能促进花球的生 Cauliflower is a cruciferous plant, its flower ball is one of the favorite vegetables. To this end, we use gibberellin test to explore cauliflower early ball, increase production methods. Test varieties are Japan Snow Mountain cauliflower, gibberellic acid concentration of 50,100,150ppm, water control. A total of four plots repeated three times. When the seedlings grew 4 leaves and one heart, the leaves were sprayed with gibberellin at the above concentration. After 2 weeks, 50,100 ppm of gibberellic acid was found to promote the formation of cauliflower flower buds, and 50 ppm of The best results, 7 days earlier than the control group now the ball, and can promote the health of the flower ball
