摘　　要：采用盆栽法,研究蚯蚓粪和泥炭对凤仙花生长发育的影响;分析不同栽培基质条件下凤仙花的株高、茎粗、生物量、光合色素含量、光合速率及花期的差异。结果表明,不同栽培基质比例整体表现出m(泥炭):m(蛭石):m(珍珠岩)为2∶1∶1最优,此时凤仙花的株高、茎粗最大,开花质量最好;纯泥炭栽培基质最差;复合栽培基质对凤仙花生长的促进作用优于单一栽培基质。The effects of wormcast and peat on growth of impatiens balansae by means of potted cultivation arestudied. The plant height, steam diameter, biomass, content of photosynthetic pigments, photosynthetic rate andflowering phase of impatiens balansae in different growing medias are analyzed. The results show that,when m(peat): m(vermiculite): m(perlite) = 2 ∶ 1 ∶ 1, the height and stem diameter of impatiens balansaeare best, the flowering quality is best, that is worst with only peat. The compound growing media are superior tothe single growing medium for impatiens balansae.
