菜花生长发育的适温范围窄,花球生长适温白天是20℃,夜间8℃,以白天18℃,夜间10～13℃为最好。如温度过低,则不易形成花球;气温高于20℃以上,花枝发育快,花球易松散,降低商品价值,造成减产。那么如何才能获得优质高产的菜花呢? 其技术要点如下。 一、选用对路品种是菜花丰产的前提 Cauliflower growth and development of the narrow range of suitable temperature, flower bud growth temperature during the day is 20 ℃, 8 ℃ at night, with daytime 18 ℃, night 10 ~ 13 ℃ for the best. Such as the temperature is too low, it is not easy to form a flower ball; temperature is higher than 20 ℃ above, squid rapid development, flower ball easily loose, reducing the value of the commodity, resulting in reduced production. So how to get good quality and high yield cauliflower? The technical points are as follows. First, choose the right species is a prerequisite for high yield cauliflower
