摘　　要：在温室大棚条件下,以常规土培作对照,对非洲菊切花两种有机生态基质[珍珠岩∶泥炭∶有机肥=9∶7∶4(v/v);木屑∶砻糠灰∶有机肥=7∶7∶6(v/v)]的种植效果及其再利用(即已经栽种过一年花卉)情况作了比较研究。结果表明,在不同基质上生长的非洲菊生物量、切花产量、质量、植株叶片N,P,K含量差异较大,以木屑、砻糠灰、有机肥混配的回收再利用基质的栽培效果最佳,珍珠岩、泥炭、有机肥新配的基质次之。非洲菊植株叶片N,P浓度与抗寒性有密切关系,其与冷害株比例呈显著负相关,尤以P浓度影响更大。The two organic culture mediums [perlite：peat：organic manure（v/v） = 9：7：4; saw dust：ash bran：organic manure （v/v） = 7：7：6]was compared with conventional soil culture method by cut flower of Gerberajamesonii in the greenhouse.The result showed that the biomass, flower number and quality, the concentrations of N, P, and K in plant leaves grown in various culture mediums were significantly different. The best result obtained from the recycling medium mixed with saw dust, ash bran, and organic manure, and the second favorite medium was the new mixture of perlite, peat, organic manure. The resistance to coldness of the plants was closely relative to the concentrations of N and P in the leaves. The concentrations of N and P in the leaves were negative relative to the ratios of the plants injured by the coldness. The effect of P improving resistance to coldness was greater than that N.
