6Moreover measures to control acid rain by liming in polluted area to neutralize resulted in reducing averagely 0.13 pH of soil, and the element content in soil had been improved gradually. The number of microbes had been increased in the No.2, No.3 and No.4 plots in polluted area. The quantity of bacteria had sored to 8.0×109per kilogram soil and N2-fixing bacteria also get 2.5×107per kilogram soil in Spring.

其中最理想的施石灰量为20-30Kg／100m~2，施石灰可中和土壤酸性，pH平均升高0.13，使土壤有机质、有效P、K等增加，并使林下土壤微生物数量增多；在春季，细菌数量达到8.0×10~9个／Kg干土，固氮菌达2.5×10~7个／Kg干土，从而促进了林分生长。

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。

In present study, ^60Co 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 ^89Sr by ryegrass and bahia grass.

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。

The physical characteristics of water in the soil included soil bulk density, MWHC, capillary water holding capacity and least water holding capacity were also measured by soaking and discharging experiments with samples of soil from different soil depths in all studied communities.

通过对苔藓、枯落物和土壤的野外调查与室内实验，分析了川西高山和亚高山3种主要灌丛在不同海拔梯度的地被物及土壤持水性能，其有利于加深对长江上游高山和亚高山区灌丛水文效应的认识。

The results showed that there were significant differences among fungal species or ecotypes in all above index,which varied with soil types.First,six fungi could colonize maize root on three soils,and the fungal colonization rate was higher on soil collected in the region that had been screened for cinnamon soil and brown soil.

结果表明，6种菌株在上述指标上存在显著的种间或生态型差异，土壤与菌株间存在显著的交互作用。6种菌株在3种土壤上都能与玉米形成菌根，在褐土和棕壤上大多数菌株在分离地所在地区土壤类型上的菌根侵染率较高，说明其对该土壤条件的适应性较强；在红壤强酸性土壤条件抑制了菌根真菌的侵染。
