摘　　要：以翅果油树1年生幼苗为试验材料,腐殖土、黄土、营养土和泥炭土为播种基质,研究不同播种基质对翅果油树幼苗生长、生物量和根系发育的影响。结果表明:不同播种基质处理下,翅果油树幼苗生长、生物量和根系发育结果存在有效差异(p<0.05)。腐殖土和营养土处理能有效促进翅果油树幼苗生长和生物量积累,翅果油树幼苗的苗高、地径、生物量分别比黄土提高了83.5%和59.7%,32.3%和28.6%,73.6%和31.3%;4种处理的叶面积差异无效,黄土处理的比叶面积分别高其它3个处理73.3%、42.8%和14.3%;茎生物量营养土处理最高,分别高腐殖土7.3%,黄土74.1%。综上所述,黄土基质下的苗高、地径、生物量等方面生长表现最差,说明黄土不利于翅果油树的生长,而腐殖土和营养土处理根系质量较好,根系生长相对发达且均衡,适合作为翅果油树育苗基质。Taking one-year-old seedlings of Elaeagnus mollis as experimental materials,the experiment of container seedling cultivation was carried out by the four types substrates of humic soil,loess,nutrient soil and peat soil to explore the effects that different soil substrates on the growth,biomass and root development of Elaeagnus mollis seedlings were studied.The results showed that different soil substrates significantly affected the growth,biomass and root development of Elaeagnus mollis seedlings(p<0.05).The humus soil and nutrient soil could effectively promote the accumulation of seedlings growth and biomass,the height,diameter and biomass of the seedlings increased by 83.5% and 59.7%,32.3% and 28.6%,73.6% and 31.3%.The leaf area was no significant difference under the four types of treatments,the specific leaf area of loess was significantly higher by 73.3%,42.8% and 14.3% respectively compared with the other three treatments.The stem biomass of nutrient soil was the highest by 7.3% and 74.1% respectively higher than humic soil and loess.The height,diameter and biomass of loess was the worst and it went against the growth of Elaeagnus mollis,the root quality of humic soil and nutrient soil was good and their root growth was relatively developed and balanced.
