摘要：

为了探索树皮替代泥炭栽培飞羽竹芋的可行性，以100%泥炭处理为对照，研究了不同复配基质的物理性状，以及对飞羽竹芋株高、冠幅、叶片数、叶面积的影响。结果表明：树皮替代部分泥炭的复配基质优于单一使用泥炭的栽培效果，最佳配比为泥炭60%+树皮40%，其次是泥炭80%+树皮20%。2种配方基质的容重为0.20 g/cm3左右，总孔隙度大于65%，持水力为300 g/100 g左右。飞羽竹芋上盆8个月后，比使用纯泥炭的株高增加20%，冠幅增加15%，叶片数增加2.4%，叶面积增加55%~65%。树皮替代部分泥炭培育飞羽竹芋可行，还可降低生产成本。

Abstract:

In order to screen bark instead of peat on substrate formula, the treatment of 100% peat was used as control, the mixed media of peat and bark were applied to culture Stromanthe sanguinea Sond. The results indicated that the substrate formula with 20%-60% bark had some ideal physical properties in terms of bulk density，total porosity, air-filled porosity and water retaining property, compared to the medium of 100% peat. The optimal and second substrate formula were 60% peat+40% bark and 80% peat+20% bark, respectively, in which the bulk density, total porosity and water retaining property were about 0.20 g/cm3, 65% and 300 g/100 g, respectively. The suggested two media mentioned above could achieve more than 20% height, 15% crown width, 2.4% number of blade and 55%-65% leaf area, compared with the control.The optimal and second substrate formula were 60% peat + 40% bark and 80% peat + 20% bark, respectively, in which the bulk density，total porosity and water retaining property were about 0.2~0.3g/cm3，65% and 300g/100 g, respectively. The suggested two media mentioned above could achieve more than 20% height, 15% crown width, 2.4% number of blade and 55%~65% leaf area, compared with the control.
