B_9提菊花栽培中常用的生长抑制剂。一般认为浓度在2000倍左右为宜。但88年我们用1000倍液喷施,却发现效果更好,且无不良影响。于是,89年我们进一步采用600倍、800倍、1000倍三种浓度对10个菊花品种(均为独本菊)进行试验。以喷施清水为对照,观察分析最佳浓度和矮化效果。
B_9 Mention growth inhibitors commonly used in chrysanthemum cultivation. Generally believed that the concentration of about 2000 times is appropriate. However, in 1988, we spray 1000 times, but found that the effect is better, and no adverse effects. Therefore, in 1989, we further tested 10 varieties of chrysanthemum (all single chrysanthemum) with 600 times, 800 times and 1000 times. To spray water as a control, observe and analyze the optimal concentration and dwarfing effect.
