摘要

研究了不同基质配方对观赏凤梨‘丹尼斯’营养生长的影响。结果表明，以体积比为1：1的椰糠和珍珠岩混合而成的基质对‘丹尼斯’的营养生长最为有利．该基质有利于植株干物质积累．对促进根系的生长及干物质的积累作用尤其明显，同时使植株叶片数增多，株型紧凑、美观。%Through conducting the treatments of different mediums, the vegetative growth was studied on Guzmania ＂Denise＂. The results showed that for the vegetative growth of Guzmania ＂Denise＂, the medium mixed by 1 volume coconut husk and 1 volume perlite was the best.
