为了保证郁金香切花周年供应市场,人们在栽培方式上不断创新。其中,水培法以集约化、规模化、工厂化等特点在生产上被越来越广泛地应用。郁金香是秋植球根花卉,自然条件下秋季种植生根,春季发叶开花,夏季休眠。根在5℃以上开始生长,生根适温9℃～13℃。植株生长最适温度15℃～18℃,花芽分化最适温度17℃～23℃。露地栽培经自然低温期后,于3月下旬至4月上旬开花;促成栽培种球须在花芽分化后,经9℃或5℃的低温处理才能提早开花。种球的准备自繁种球宜在夏初收获,然后分级(一般周
In order to ensure the annual supply of tulip cut flowers market, people in the cultivation of innovative ways. Among them, the hydroponics method is more and more widely used in production due to the characteristics of intensive, large-scale and factory-oriented. Tulip is the autumn planting bulbous flowers, rooting in autumn under natural conditions, the spring leaves flowering, summer sleep. Roots began to grow above 5 ℃, rooting temperature 9 ℃ ~ 13 ℃. Plant growth optimum temperature 15 ℃ ~ 18 ℃, flower bud differentiation optimum temperature 17 ℃ ~ 23 ℃. Open-field cultivation after natural low-temperature period, from late March to early April flowering; to promote the cultivation of bulbs must flower bud differentiation, the 9 ℃ or 5 ℃ low temperature treatment to early flowering. Bulbs prepared since the breeding balls should be harvested in the early summer, and then graded (usually weeks
