污泥堆肥用于观叶植物银叶菊无土栽培的研究

［目的］筛选银叶菊无土栽培的最佳基质。［方法］以污泥堆肥、蛭石和珍珠岩为原料配制银叶菊无土栽培基质，研究不同基质对银叶菊营养生长的影响。［结果］50%污泥＋50%（蛭石＋珍珠岩）基质中银叶菊冠幅、株高长势最好，60%污泥＋40%（蛭石＋珍珠岩）次之;60%污泥＋40%（蛭石＋珍珠岩）基质中银叶菊叶长、叶宽长势最好，叶片N、P含量最高，50%污泥＋50%（蛭石＋珍珠岩）次之;50%污泥＋50%（蛭石＋珍珠岩）和60%污泥＋40%（蛭石＋珍珠岩）基质中银叶菊的生物量极显著高于蛭石＋珍珠岩基质中的银叶菊。［结论］银叶菊无土栽培的适宜基质为50%污泥＋50%（蛭石＋珍珠岩）和60%污泥＋40%（蛭石＋珍珠岩）。

Study on Soilless Culture of Foliage Plant Senecio cineraria with Sludge Compost

Objective] The study was to screen out the optimum matrix for soilless culture of Senecio cineraria.Method] With sludge compost,vermiculite and perlite as the materials,the matrix for soilless culture of S.cineraria was prepared and the effects of different matrix on growth of S.cineraria were studied.Result] The growth vigor of crown width and plant height of S.cineraria in 50% sludge+ 50%(vermiculite +perlite) were the best,the following were those in 60% sludge+40%(vermiculite+ perlite).The growth vig...
