[目的]为空气凤梨快速繁殖提供技术指导.[方法]以4个空气凤梨品种的无性繁殖系为材料,研究不同肥料浓度(凤梨专用肥稀释500、1 000、1 500倍)及施肥周期(14 d/次和28 d/次)对其生长的影响.[结果]危地马拉小精灵和阿拉杰这2个品种对肥料不敏感,施肥后其外观表现无明显变化;维路提纳和富奇斯这2个品种对肥料较敏感,施肥可显著增加其绿色,并有效延缓其老叶的衰败速率;不同肥料浓度的施肥效果依次为:稀释500＞稀释1 000＞稀释1 500倍,不同施肥周期的施肥效果表现为:14 d/次＞28 d/次;维路提纳和富奇斯的增重率较高,另外2个品种的增重率较低.[结论]14 d/次施肥处理最有利于空气凤梨生长,且肥料浓度应控制在稀释1 000～1 500倍.

[Objective] The study was to provide the technical guidance for rapid propagation of Tillandsia. [Methods] The clones of 4 Tillandsia varieties were taken as the materials, the effects of different fertilizer concentration (pineapple-special fertilizer diluted 500, 1000 and 1500 times) and fertilization cycles (14 d/time and 28 d/time) on growth of them were studied. [Results] The Tillandsia ionantha Guatemala and Tillandsia araujei were not sensitive to fertilizer, and their appearance had no obvious change after fertilization. Tillandsia velutina and Tillandsia fushsii were sensitive to fertilizer, and fertilization could significantly increase their greenness and effectively delay the senescence rate of their old leaves. The fertilization effects of different fertilizer concentration in order was: diluted 500 times＞diluted 1 000 times＞diluted 1 500 times, and those of different fertilization cycles showed as 14 d/time> 28 d/time. The weight gain rates of T. velutina and T. fushsii were high, while those of the other 2 varieties were low. [Conclusion] The treatment of fertilization with 14d/time was the most beneficial to growth of Tillandsia and the fertilizer concentration should be controlled in the range of diluted 1 000-1 500 times.
