一般无土栽培,大都采用河砂、蛭石、颗粒塑料等作为固定盆花的基质。可是这些基质,或质重易压伤肉质根系;或棱角锐利、堆积紧凑,透气力低,粗根系难以伸长;或表面光滑,不具吸水力,水肥不易保持等等,总难成为最佳基质。笔者从邮寄苗木用苔藓植物裹根、充填空隙,而邮途保活率颇高的现象中得到启发,便试着以其作为基质培植各类花木,结果均获得比河沙、蛭石、塑料颗粒更好的效果。尤其是栽培兰花3周内就开始长新根,比土培出新根的速度要快8倍许。这是什么缘故呢? 一、它具有特殊的保水能力苔藓植物,大都是丛生的,密集的株间有无数的空隙,可起到毛细管样 Generally soilless culture, most of the river sand, vermiculite, particle plastic, etc. as a fixed potted flower matrix. However, these matrices, or the quality of the roots can easily crush the fleshy; or sharp edges and corners, compact accumulation, low permeability, rough root elongation is difficult; or smooth surface, no water absorption, water and fertilizer is not easy to maintain, etc., difficult to become the best substrate . The author from the mail seedlings with bryophytes wrapped roots, fill the gap, and the high survival rate of the phenomenon was inspired, they tried to use it as a substrate to cultivate all kinds of flowers and trees, the results were obtained than sand, vermiculite, plastic Particles better effect. Especially the cultivation of orchids began within 3 weeks long new roots, faster than the new root soil culture 8 times Xu. What is the reason? First, it has a special ability to retain water bryophytes, mostly tufted, dense strains of numerous gaps between strains, can play a capillary-like
