结球甘兰为二年生作物,约经二个月的2～6℃低温期,才能通过春化阶段,抽苔、开花、结籽。因此在低温时间短的南方地区留种困难。结球甘兰用赤霉素处理的不时留种,不经过低温阶段,同样能抽苔、开花、结籽。而且只要安排适当,一年还可以留二次种。在加速结球甘兰繁殖和增加世代方面,比冷库处理、异地采种等方法更加经济有效。一、材料和方法黑叶小平头甘兰,7月13日定植,8月7日开始处理,9月25日结束,处理时叶层为11～17层,已包心。鸡心甘兰5月24日
Cinnamon as biennial crops, about two months after the 2 ~ 6 ℃ low temperature, in order to pass the vernalization stage, bolting, flowering, seed. Therefore, it is difficult to stay in the southern area where the temperature is short. Cinnamon cabbage treated with gibberellic acid from time to time to stay, not through the low temperature stage, the same can be bolting, flowering, seed. And as long as arranged properly, you can stay twice a year species. In accelerating Cyclobalanopsis and increasing generations, it is more economical and effective than cold storage and seed collection in other places. First, the material and methods Black kobayashi, colonization July 13, August 7 began to deal with the end of September 25, dealing with the leaf layer 11 to 17 layers, has been packed.
