摘　　要：为筛选出适合彩叶草栽培的新型专用型栽培基质,以腐熟中药渣、腐熟菇渣、泥炭、珍珠岩和泥土为原料,按照不同比例复配成5种栽培基质,以泥土作为对照,研究不同配比栽培基质对彩叶草奇才系列金黄色和红色品种株高、茎粗、分枝数、冠幅、叶长、叶宽、地上部鲜重、地下部鲜重、地上部干重和地下部干重的影响。结果表明:基质1(腐熟中药渣∶泥炭∶珍珠岩∶泥土为2∶1∶0.5∶1)和基质2(腐熟中药渣∶腐熟菇渣∶泥炭∶珍珠岩∶泥土为4∶1∶1∶1)中栽培的彩叶草在株高、茎粗和分枝数等10个性状指标均明显优于其余复配栽培基质和对照,其中以腐熟中药渣含量比例更高的效果更好,因此基质2可作为彩叶草栽培的专用基质。The effects of five compound substrates with different ratio of decomposition Chinese herb residue,decomposition mushroom residue,peat,perlite and garden soil on height,stem girth,branch number,crown diameter,leaf length,fresh weight of aerial part,fresh weight of underground part,dry weight of aerial part and dry weight of underground part of two Coleus blumei varieties to screen a new special cultivation substrate for cultivation of Coleus blumei.Results:10 character indexes of two Coleus blumei varieties cultured on Substrate Ⅰ(decomposition Chinese herb residue∶peat∶perlite ∶ garden soil=2∶1∶ 0.5 ∶ 1)and Substrate Ⅱ(decomposition Chinese herb residue∶peat∶perlite∶garden soil=4∶1 ∶1∶ 1)are higher than SubstrateⅢ,SubstrateⅣ,SubstrateⅤand CK.SubstrateⅡwith a better effect can be used as a special cultivation substrate for cultivation of Coleus blumei.
