茶花喜半阴,忌烈日,喜温暖气候,生长适温为18摄氏度至25摄氏度,略耐寒,在严寒的冬季常会遭受冻害,因此,在养护管理时要注意以下几点:秋末冬初,适当施以磷、钾肥,不施氮肥,增加茶花自身的抗冻能力。在严寒的冬季,地栽、盆栽的茶花土壤宜保持中等湿度。这样既不会烂根,又可避免茶花受冻伤根。用塑料袋套封花盆。此方法十分简易,对茶花业余爱好者较适宜。中耕松土,使表面土壤疏松,形成防冻隔离层,保暖效果很好。我国北方栽培茶花,由于气温低,一般品种必须入温室越冬。
Camellia hi half cloudy, bogey hot day, hi warm climate, growth temperature of 18 degrees Celsius to 25 degrees Celsius, slightly cold, cold frost often suffer in the winter, therefore, in the conservation management should pay attention to the following points: Apply phosphorus, potash, no nitrogen fertilizer, increase their antifreeze ability. In the cold winter, planted, potted Camellia soil should maintain moderate humidity. This will not rotten roots, but also to avoid the camellia frostbite root. Cover the flowerpot with plastic bag. This method is very simple, more suitable for Camellia amateurs. Cultivation of loose soil, so that the surface of loose soil, the formation of antifreeze insulation, thermal effect is very good. The cultivation of Camellia in northern China, due to low temperatures, the general varieties must be winter into the greenhouse.
