郁金香是重要的春季球根花卉,宜作切花,中矮性品种可盆栽,而促成栽培是在盆栽基础上,开发郁金香的非自然花期,即通过对种球的变温处理,打破花原基和叶原基的体眠,消除抑制花芽萌发的因素,促使郁金香适时进行花芽分化,再通过人为的增温、补光以及激素处理等措施,使郁金香在非自然花期开花。一、种球的变温处理:先把挖出的鳞茎经34℃温度处理1周,再放至20℃温度下贮藏1个月,至花芽分化
Tulip is an important spring bulbous flower, should be used as cut flowers, potted plants in the short species, and to promote cultivation is based on potted plants, the development of tulip unnatural flowering, that is, through the bulbs of temperature treatment, breaking the primordial and leaf primordia Body sleep, eliminate the inhibition of flower bud germination factors, prompting tulip timely flower bud differentiation, and then through artificial warming, fill light and hormone treatment and other measures to make tulip flowering in the non-natural flowering. First, the bulbs of variable temperature treatment: First dug out of the bulb by 34 ℃ temperature for 1 week, and then stored at 20 ℃ temperature for 1 month to flower bud differentiation
