不同配方基质对盆栽美人蕉生长的影响

Effect of Different Formula Substrate on Growth of Potted Canna

以园林植物废弃物堆肥(以下简称堆肥)为主,以泥炭、炉灰、珍珠岩、泥土为辅,配制成不同的配方基质,并以泥炭为对照,研究不同配方基质对盆栽美人蕉生长的影响效果。试验共设计5个配方,即A(泥炭)、B(堆肥∶泥炭∶泥土=5∶4∶1)、C(堆肥∶炉灰∶泥炭=5∶3∶2)、D(堆肥∶炉灰∶泥土∶珍珠岩=5∶2∶2∶1)、E(堆肥∶炉灰∶泥土∶泥炭=5∶2∶2∶1)4个重复。研究结果表明:配方B(堆肥∶泥炭∶泥土=5∶4∶1)能显著提高美人蕉株高、冠幅、茎粗、叶片数,增强美人蕉的观赏价值,是盆栽美人蕉的最佳配方基质。

Using garden plant waste compost as the basic material, different formulas were formulated by mixing peat, ash, perlite and soil. As control treatment, a peat-based substrate was employed. Effects of different formula substrate on growth of potted canna were studied. Five different substrate formula treatments were applied in formula experiment design, namely A(peat), B(compost: peat: soil=5: 4 : 1), C(compost: ashes: peat=5 : 3 : 2), D(compost: ashes: soil: perlite=5 : 2 : 2 : 1), E(compost :ash :soil: peat=5 :2 :2 :1). Results showed that formula B (compost: peat: soil=5:4:1) significantly improved plant height, crown width, stem diameter, number of leaves and enhanced the ornamental value of Canna. So are formula B the best for growth of potted Canna.
