君子兰喜温、喜光,不耐寒冷。冬季要想养好君子兰,关键需加强以下几方面管理。1.管土肥。君子兰喜疏松肥沃的中性或弱酸性腐殖质土,应少施氮肥,多施磷肥、钾肥。蛋壳粉与沤熟的鱼腥水就是很好的磷肥,糠灰、烟灰是易得的钾肥。施肥一定要适量,切忌施入浓肥和未经发酵腐熟的生肥,否则,容易引起叶尖枯焦或腐烂。冬季若新叶出现斑点、根系发黄,说明施肥过多;而新叶窄、薄且颜色特别浅则是缺肥的表现。
Gentleman orchid warm, hi light, cold intolerance. In order to keep Clivia in winter, the key needs to be strengthened in the following aspects of management. 1. Pipe soil fertilizer. Gentleman Lan Xi loose fertile neutral or weakly acidic humus soil, should be less nitrogen fertilizer, more phosphate, potassium. Egg shell powder and cooked fishy fish is a good phosphate fertilizer, bran dust, ash is easy to get potash fertilizer. Fertilization must be modest, should not be applied into the fat and unfermented composting, otherwise, it is easy to cause leaf scorch or decay. If the new leaf spotted in winter, the root yellow, indicating excessive fertilization; and new leaves narrow, thin and particularly shallow color is the performance of lack of fat.
