郁金香是如何进行田间管理的

郁金香.jpg

调控温度

  郁金香的生长期适温为5-20℃,温度为15-18℃,植株的生育温度应保持在0-25℃。郁金香根系的生长温度宜在5℃以上,14℃以下,10℃左右较好?;ㄑ糠只氖饰挛?7-23℃。另外,郁金香有较强的耐寒性,冬季可耐-35℃的低温,当温度保持在8℃以上时开始生长。

水分管理

  栽培过程中切忌灌水过量,但定植后一周内需水量较多,应浇足,发芽后需水量减少,在开花时水分不能多,浇水应做到"少量多次"如果过于干燥,生育缓,郁金香生长期间,空气湿度以保持在80%左右为宜。

光照条件

  种球发芽时,其花芽的伸长会受到阳光的抑制。因此须深植,并进行适度遮光,以防止直射阳光对种球生长产生不利的影响。

土壤和施肥

  以沙壤土为好,土壤酸碱度以中性偏碱为好。郁金香较喜肥,栽前要施足基肥。一般采用干鸡粪或腐熟的堆肥作基肥并灌水,定植前2-3天仔细耕耙土质疏松。种球生出两片叶后可追施1-2次液体肥,生长旺季每月施3-4次氮、磷、钾均衡的复合肥,花期要停止施肥,花后施1-2次磷酸二氢钾或复合肥的液肥。
