让郁金香反季节开花,生产难度较大,除要选择优质的种球及配备必要的温室设施外,在生产中促进根系生长和保护根系,也是非常重要的。优质的郁金香种球中含有的营养基本上可供其生长发育,故一般不需要往基质中加入过多肥料。但郁金香在生长过程中所需要的水分必须由根系供给,特别是在蕾花期更不可缺水,所以如果根系生长和保护不好,就不能保证花的质量,甚至不开花。 1998年笔者所在单位种植了少量郁金香,是直接种在花盆中的,从生根室移入温室时根系没有受伤,故当年出花
It is also very important for tulips to bloom in the anti-season and produce more difficultly. In addition to selecting high-quality bulbs and equipping the necessary greenhouse facilities, it is also very important to promote root growth and protect roots in production. High-quality tulip bulbs contained in the nutrition is basically available for its growth and development, it is generally not necessary to add too much to the matrix fertilizers.
