摘　　要：为探索短序润楠(Machilus breviflora)容器苗生长的最佳基质,以黄心土、泥炭土、椰糠、珍珠岩、有机肥为试验材料,通过不同的基质配比组合成10种混配基质进行育苗试验,对短序润楠容器苗的生长进行研究。结果表明,不同的基质配比对短序润楠的生长量、生物量以及叶片叶绿素SPAD值均有明显的影响。通过主成分分析结果可知,当基质配比为15%黄心土+50%泥炭土+20%椰糠+10%珍珠岩+5%有机肥时,短序润楠的生长最好,综合得分最高。Aiming to explore the best substrate for the growth of container seedlings of Machilus breviflora,the growth of container seedlings of Machilus breviflora by taking yellow heart soil,peat soil,coconut bran,perlite and organic fertilizer as experimental mate⁃rials and combining them into ten kinds of mixed substrates through different matrix ratios were studied.The results showed that differ⁃ent matrix ratios had obvious effects on the growth,biomass and leaf chlorophyll SPAD value of Machilus breviflora.The results of prin⁃cipal component analysis showed that the comprehensive score of Machilus breviflora was the highest with the best growth when the ma⁃trix ratio was 15%yellow core soil+50%peat soil+20%coconut bran+10%perlite+5%organic fertilizer.
