Simple detection of spore germination of two arbuscular mycorrhizal fungi, Gigaspora gigantean and Glomus mosseae, in soilless media was investigated by using Millipore surface germination method.

利用滤膜表面发芽法可简单侦测丛枝菌根菌Gigaspora gigantean及Glomus mosseae孢子在无土介质中发芽情形。

In this experiment, typical ectomycorhizal fungi strains(Lactarius delicious 01, 02 and 03) were isolated from Three-Gorges Reservoir where Pinus Massoniana was very popular. And Suillus placidu 504(sp 504) and Laccaria bicolor S238N (Lb 23 8N) typical in South China were also chosen to study the effects of ectomycorrhizal fungi on the growth and nutrient absorption of Pinus Massoniana. And the culture characteristics of three strains of Lactarius delicious were also studied. The object of this study is to supply techniques in culturing ectomycorrhizal seedlings for planting trees in Three-Gorges Reservoir.

试验从马尾松大面积分布的三峡库区，分离出代表当地生态条件的松乳菇(Lactarius deliciosus 1、2和3)，并选择中国南方具有代表性的华南牛肝菌(Suillus placidu 504)和双色蜡蘑(Laccaria bicolor Lb S238N)，研究了松乳菇3个菌株的培养特性，并利用Lb S238N、Sp 504、Ld01和Ld03苗床接种马尾松，观察了它们对幼苗的生长和养分吸收的影响，目的是为三峡库区马尾松的植树造林提供培育菌根化苗木技术。

It shows that total species diversity of mycorrhizal fungi isolated from R.

In present study,~(60)Co γ-rays was used to irradiate soil with doses of 3.0 kGy and 25.0 kGy,respectively,to discriminate between arbuscular mycorrhizal fungi and other soil microorganisms,while soil without irradiation was used as control to study the effects of soil microorganisms on uptake of ~(89)Sr by ryegrass and bahia grass.

用3.0和25.0 kGy剂量的60Coγ射线分别对供试土壤进行了辐照处理，以区分土壤中的内生菌根菌和其他土壤微生物；并以未经辐照处理的土壤为对照研究了土壤微生物对黑麦草和百喜草吸收89Sr的影响。

文章摘要：用3.0和25.0kGy剂量的^60Coγ射线分别对供试土壤进行了辐照处理，以区分土壤中的内生菌根菌和其他土壤微生物；并以未经辐照处理的土壤为对照研究了土壤微生物对黑麦草和百喜草吸收^89Sr的影响。

Although AM fungi and other soil microorganisms had no significant effect on above ground biomass in ryegrass and bahia grass,both AM fungi and other soil microorganisms decreased the uptake of~(89)Sr in the two grass species,though to a more or less extant.

尽管内生菌根菌和其他土壤微生物对黑麦草和百喜草的地上部分生物量没有明显影响，但它们都不同程度地降低了两种草对89Sr的吸收。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
