The aim of this study was to determine the influence of Eisenia fetida vermicompost (VC) added to forest nursery soil. The chemical reaction in the soil and selected microorganisms, such as bacteria, fungi and nematodes, were assessed. Larch seedlings were cultivated for 2 years in pots with nursery soil as a control and VC-amended soil in two doses: 10% (V10) and 20% (V20) v/v. One important observation was the connection between the addition of VC and the improvement of the plant's biometry and a much higher level of mycorrhization with increasing Suillus sp. Vermicompost modified the nematode community by reducing plant parasitic nematodes, and significantly increasing bacterial and fungivorous, as well as predatory nematodes. Actinomycetes bacteria, which were present in a proportion of 2.2% in the control soil, increased to 10.5% in V10, and to 5.4% in V20. Bacillus spp. increased along with the amount of VC from <0.01% in the control to 2.2% in V10 and to 2.7% in V20. The C:P ratio correlated negatively while the C:K ratio and N-NH₄ concentration correlated positively with the abundance of Bacillus spp. Toxigenic Penicillium spp. and Fusarium spp. were suppressed. The stability of VC-amended soil system with respect to enzymatic activity was rather high, except for o-diphenol oxidase which was strongly reinforced by the VC. The enzyme activity values for all enzymes were correlated with an improvement in the values of the microbiological, biometric and nematode parameters and increased mycorrhization. One favorable modification, which was manifested in better seedling growth, was the effect of VC on the development of Suillus-morphotype mycorrhizal fungi, fungal feeder nematodes and Bacillus spp. Vermicompost may therefore be recommended in practice as a method of sustainable management for soil protection in larch forest nurseries.

本研究的目的是确定添加到森林苗圃土壤中的Eisenia fetida vermicompost (VC)的影响。评估了土壤中的化学反应和选定的微生物，如细菌、真菌和线虫。落叶松幼苗在盆中培养 2 年，苗圃土壤作为对照，并以两种剂量的 VC 改良土壤：10% (V10) 和 20% (V20) v / v。一个重要的观察结果是添加 VC 与植物生物特征的改善之间存在联系，以及随着Suillus 的增加，菌根化水平要高得多。sp. 蚯蚓粪通过减少植物寄生线虫并显着增加细菌和食真菌以及捕食性线虫来改变线虫群落。放线菌在对照土壤中的比例为 2.2%，在 V10 中增加到 10.5%，在 V20 中增加到 5.4%。芽孢杆菌属 随着 VC 的量从对照组的 <0.01% 增加到 V10 的 2.2% 和 V20 的 2.7%。C:P 比率呈负相关，而 C:K 比率和 N-NH ₄浓度与芽孢杆菌属的丰度呈正相关。产毒青霉属。和镰刀菌属 被压制。VC 改良的土壤系统在酶活性方面的稳定性相当高，除了被 VC 强烈增强的邻二酚氧化酶。所有酶的酶活性值与微生物、生物特征和线虫参数值的改善以及菌根化的增加相关。一种有利的修饰，表现在更好的幼苗生长，是 VC 对牛肝菌属-形态型菌根真菌、真菌饲养线虫和芽孢杆菌属的发育的影响。因此，在实践中可以推荐蚯蚓堆肥作为落叶松林苗圃土壤保护的可持续管理方法。
