东北天气寒冷,无霜期短,而适合切花的花卉大都不耐严寒,并且需要较高的栽培技术措施,这给东北鲜切花的生产增加了困难。目前,世界流行的四大切花月季、康乃馨(香石竹)、唐菖蒲和菊花在东北都可以栽培。它们的营养生长期都比较长,如果只靠日光温室或人工温室生产切花,就会大大增加成本,提高花价,降低经济效益,甚至造成滞销或亏损。我认为,从育种、栽培或其它化控技术上可以解决延长花期、提高产花量的问
Cold weather in the northeast, frost-free period is short, and flowers are mostly suitable for cut flowers intolerance cold, and require higher cultivation techniques and measures, which gives the Northeast fresh cut flowers production increased difficulties. At present, the world’s four popular cut rose, carnation (carnation), gladiolus and chrysanthemum can be cultivated in the northeast. Their vegetative growth period is relatively long, if only by solar greenhouse or artificial greenhouse cut flowers, it will greatly increase costs, increase flower prices, reduce economic efficiency, and even lead to poor sales or loss. I think, from breeding, cultivation or other chemical control technology can solve the problem of prolonging the flowering period and increasing the flowering rate
