中文摘要	菌根真菌在干旱半干旱地区退化生态系统植被恢复与重建中具有重要作用。以科尔沁沙地乡土树种五角枫(Acer mono)和榆树(Ulmus pumila)及主要造林树种白蜡(Fraxinus chinensis)和樟子松(Pinus sylvestris var. mongolica)为供试植物,通过科尔沁沙地菌根化造林试验,分析4种造林幼苗接种菌根菌剂后幼苗的菌根侵染率、形态学指标、生物量积累和分配以及根际土壤养分在一个生长季内的变化。结果表明: 两种菌根菌剂能较好地侵染幼苗,接种菌根菌剂显著提高了4种幼苗的株高、基径、顶枝长和生物量; 显著影响幼苗的生物量分配,接种内生菌剂的白蜡根冠比显著减小,接种外生菌剂的樟子松根冠比显著增加; 相关分析表明,菌根侵染率与白蜡幼苗株高和顶枝长呈显著正相关,与樟子松幼苗输导根质量、地上生物量和总生物量呈显著正相关; 接种菌根菌剂还能提高根际土壤有机质和全氮含量,改良幼苗生长基质,但差异不显著。4种造林幼苗均表现出了显著的菌根效应,提示菌根菌剂在干旱贫瘠地区造林中具有很强的应用价值。
英文摘要	Mycorrhizal fungi play key roles in vegetation restoration and vegetation reconstruction of degraded ecosystems in arid and semi-arid lands. In the present study,a mycorrhizal afforestation experiment in Horqin sandy land was carried out to understand the influence of two mycorrhizal fungi inoculums (arbuscular mycorrhiza inoculum and ectomycorrhizal inoculum) on growth of four kinds of afforestation seedlings. We analyzed mycorrhizal colonization rate and morphological indicators,accumulation and allocation of biomass,and rhizosphere soil nutrients of seedlings of two native species Acer mono and Ulmus pumila,and two introduced species Fraxinus chinensis and Pinus sylvestris var. mongolica in Horqin sandy land,China across one growth season. The results showed that: (1) Both mycorrhiza inoculums could well colonize the roots of the four kinds of seedlings. Inoculation of the mycorrhiza inoculums significantly increased the plant height,basal radium,crown stem length and biomass of all tree species. (2) Inoculation with the mycorrhiza inoculums on roots of seedlings significantly affected the allocation of biomass (P<0.05); the root-shoot ratio significantly decreased in Fraxinus chinensis seedlings,and significantly increased in Pinus sylvestris var. mongolica seedlings. (3) The mycorrhizal colonization rate was significantly positively correlated with the plant height and crown stem length of Fraxinus chinensis seedlings,and significantly positively correlated with the coarse root dry mass,shoot biomass and total biomass of Pinus sylvestris var. mongolica seedlings. (4) Inoculation of the mycorrhiza inoculums also increased the contents of organic matter and total nitrogen of rhizosphere soil,which can improve the soil matrix of seedling growth,but the difference was insignificant (P>0.05). Mycorrhizal effect of the four kinds of afforestation seedlings was significant,which indicated that it was very valuable to apply mycorrhizal fungi inoculum to afforestation in arid and barren regions.
