近年来长春市出现了不少二年开花的君子兰,他们多是坚持常年施肥的结果。经验证明,君子兰的环境温度降到25℃以下,通风良好,夏季也可照样施肥。降温的办法有: (一) 土窖降温:挖一个1—1.5米深的土窖,将君子兰放到窖底部,早晚可使其见阳光; (二) 搭荫棚:在通风处用苇帘等为君子兰搭一荫棚,有葡萄架效果更好; (三) 水池降温:把君子兰放到水槽上用硬质物垫起,既能降温又能增加湿度; (四) 挂窗帘:如君子兰放在窗台上,可挂一白色带眼的窗帘,每天用清水湿一次; (五) 铺锯末洒水:可将花盆底部垫一层锯末或河沙,每天向其周围喷水; (六) 自然通风:把花盆放在过道或土地、水泥地上,既通风又降温。
In recent years, Changchun City, there have been many flowering Clivia, they are mostly the result of persistent fertilization. Experience shows that the climax of the ambient temperature dropped below 25 ℃, well-ventilated summer fertilization can also be the same. Cooling methods are: (A) of the pit cooling: dig a 1-1.5 m deep cellar, the Clivia into the bottom of the pit, sooner or later make it see the sun; (B) shade shed: ventilation in the reed curtain (3) pool cooling: the Clivia put on the sink with a hard mat pad, both cooling and increase humidity; (D) hanging curtains: such as Clivia Put on a window sill, can be hung with a white curtain with white eyes, wet with water once a day; (5) sawing at the end of sprinkler: the bottom of the pot can be a layer of sawdust or sand, daily water spray to the surrounding; Natural ventilation: the flower pot on the aisle or land, concrete floor, both ventilation and cooling.
