As a step to elucidate the mechanism of expression of potential forest-soil microbes, the following censuses and experiments were carried out.The biomasses of soil organisms, namely fungi, bacteria, crystal violet-resistant bacteria, cellular slime molds, oribatid mites, nematodes, and enchytraid worms decreased immediately after the application of urea(800 g/m^2) to the forest soil. The biomasses of bacteria, crystal violet-resistant bacteria, and slime molds in urea-treated soil showed higher values than those in nonurea-treated soil (=control) at about the same time as the occurrence of the early succession of ammonia fungi, while, those of oribatid mites and soil Arthropleona showed higher values than those in the control throughout the period of the occurrence of the ammonia fungi.Amblyosporium botrytis grew vigorously under neutral to alkaline conditions at both high concentration of NH_4-N and high water content. Asobolus denudatus grew vigorously under neutral to alkaline conditions. Coprinus phlyctidosporus grew vigorously at a high concentration of NH_4-N. Lyophyllum tylicolor and Hebeloma vinosophyllum showed tolerance to a high concentration of NH_4-N.These and the results obtained from the correlation analyses among the degree of the occurrence of the ammonia fungi, biomasses of other soil organisms and the condition of the soil suggest that the ammonia fungi are a kind of the groups of the potential forest-soil microbes, which begin to propagate at the ecological gap, namely the condition under the decrease of biomasses of soil organisms caused by a high concentration of NH_4-N at an alkakaline condition, and then grow vigorously in these soil because of their adaptation to these environments.

作为阐明潜在森林土壤微生物表达机制的一步，进行了以下普查和实验。土壤生物的生物量，即真菌、细菌、抗结晶紫细菌、细胞粘菌、甲螨、线虫，在森林土壤中施用尿素（800 g/m^2）后，enchytraid蠕虫立即减少。与氨真菌早期演替发生的时间大致相同，经尿素处理的土壤中的细菌、抗结晶紫细菌和粘菌的生物量显示出比未经尿素处理的土壤（=对照）更高的值。在整个氨真菌发生期间，甲螨和土壤节螨均表现出高于对照的值。 灰霉病在中性至碱性条件下，在高浓度NH_4-N和高含水量。 Asobolus denudatus 在中性至碱性条件下生长旺盛。草孢鬼伞在高浓度NH_4-N下生长旺盛。真姬菇和Hebeloma vinosophyllum对高浓度NH_4-N表现出耐受性。结合氨真菌发生程度、其他土壤生物生物量与土壤状况的相关性分析结果表明，氨真菌是一类潜在的森林-土壤微生物类群，它在生态间隙开始繁殖，即高浓度氨引起的土壤生物生物量减少的条件。 NH_4-N在碱性条件下，由于适应了这些环境而在这些土壤中生长旺盛。
