不同栽培基质对纹瓣兰组培苗生长的影响

Effects of different culture media on the growth of test-tube seedlings of Cymbidium aloifolium

为探讨不同成分的基质对兰属植物纹瓣兰组培苗生长的影响,结合7种栽培基质处理方式,研究纹瓣兰组培苗的移栽成活率、根系生长及幼株生长指标,结果表明,珍珠岩+泥炭+松树皮(1∶2∶3)是较好的组培苗移栽基质,成活率持续高达99.2%,新根发育较好;瓦砾+花生壳+珍珠岩+木炭(3∶3∶1∶1)对纹瓣兰的生长发育综合评价最好,营养生长形态指标显著优于泥炭及水苔等单一栽培基质。因此,混合基质的相互协调方面优于单一基质,且基质来源广泛、价廉、无污染。

In order to understand the effects of culture media on the growth of test-tube seedlings of Cymbidium aloifolium, seven kinds of media treatment were designed to research the survival rates, root activity, and morphological indexes. The results showed that the test-tube seedlings survived best on the substrate combination of perlite： peat moss： bark at a rate of 1：2：3, survival rate was up to 99.2% stably, and the new roots grew well. The substrate combination of rubble： peanut hulls： perlite： charcoalratio at a rate of 3：3：1：1 was best for the morphological index of growth, significantly enhanced the terms of vegetable growth, and was better than the media of peat moss or sphagna singly. The coordination of combined substrates was better than the single ones, and was widely available, cheap and pollution-free.
