观赏凤梨最适宜生长的温度为日温21～32℃,夜温10～18℃。日夜温差最好相差6℃以上,以10℃为佳。夏季以25～30℃为好,稍高一些也无妨,但不可高于37℃;冬季多数种类温度不得低于10℃,少数种类在不低于5℃条件下还可生存,如果冬季温度高于15℃时基本上所有的观赏凤梨都能顺利越冬(见表)。事实上,短时的 Ornamental pineapple optimum temperature for the growth of day temperature 21 ~ 32 ℃, night temperature 10 ~ 18 ℃. The best difference between day and night temperature above 6 ℃, 10 ℃ better. Summer 25 ~ 30 ℃ as well, slightly higher is any harm, but not higher than 37 ℃; winter most species temperature not less than 10 ℃, a few species can survive at not less than 5 ℃, if the winter temperature is high At 15 ℃ basically all the ornamental pineapples can successfully wintering (see table). In fact, short-term
