蟹爪兰落蕾是花友们常遇到的一个问题。要一个不掉,难办到,掉5%属正常,超过10%甚至20%就得找原因了。落蕾有以下几方面原因:温度失控,忽高忽低。蟹爪兰孕蕾后正值冷空气频繁入侵的季节,这时多数地区的蟹爪兰已入室。而它性喜温暖凉爽气候,室温在12℃～18℃最适宜生长。如突然降温,最高气温低于10℃就易落蕾;昼夜温差过大,白天超过20℃,夜间低于10℃,也易落蕾。但如温差不大,即使气温低些,昼夜在5℃～8℃间,也不会落蕾,只是花期会推迟。最忌的足忽高忽低,故室温超过20℃时要开窗降温,寒潮来时要关闭门窗保温,注意收听天气预报。
Kalanchoe orchid bud is a friend often encountered a problem. To a can not afford, hard to do, out of 5% is normal, more than 10% or even 20% have to find the reason. There are several reasons for falling buds: Temperature out of control, fluctuating. Crab claw Lan pregnant budding after frequent cold air invaded the season, when most of the area of schistosome has entered. And it likes warm and cool climate, room temperature at 12 ℃ ~ 18 ℃ the most appropriate growth. Such as sudden cooling, the maximum temperature below 10 ℃ easy to fall bud; temperature difference between day and night is too large, more than 20 ℃ during the day and night less than 10 ℃, but also easy to fall. However, if the temperature difference is not big, even if the temperature is lower, day and night are between 5 ° C and 8 ° C, it will not drop buds, but the flowering will be postponed. The most bogey foot suddenly high and low, so when the room temperature exceeds 20 ℃ to open the window to cool down, when the cold wave to close the windows and doors insulation, pay attention to listen to the weather forecast.
