凤梨科植物对水的要求很不一致,可分为耐旱性与喜湿性两大类。耐旱性品种在干旱地区或沙漠环境中生存的那些属,以铁兰属中一些耐旱的种类为典型,长期干旱的自然环境使它们自然形成了只需少量水分的适应性,许多品种的植物体可以无需基质和附主,全靠密被于叶片上的银白鳞片从空气中吸收生长必需的水分和养分。因此,这些凤梨从不会轻易死去。春夏期间每周浇水一次就可以了,秋冬更要减少水量。喜湿性品种那些原产雨林的凤梨(观赏凤梨的大多数品种)则对空气湿度的要求较高,不适宜在干燥、缺水的环境中生长,通常具 Bromeliads on water requirements are very inconsistent, can be divided into two categories of drought tolerance and wetness. The genus of drought-tolerant cultivars that survive in arid or desert environments is typi- cally dominated by some drought tolerant species of the genus Tillandsia and naturally prolonged dry conditions allow them to naturally adapt to only small amounts of water. Many varieties of Plants can be without the substrate and attached to the Lord, thanks to dense leaves on the silver-white scales from the air to absorb the necessary growth of water and nutrients. Therefore, these pineapples will never die easily. Watering once per week during spring and summer can be, and more to reduce the amount of water in autumn and winter. Hi wet varieties Those native pineapples (most species of ornamental pineapples) have higher requirements for air humidity and are not suitable for growth in dry and water-deficient environments, usually with
