摘要

该研究的目的是在塞尔维亚中部的五个地点检查土壤利用对土壤微生物特性的影响。研究对象包括认证有机体系下的42个土壤样品、常规体系下的8个土壤样品和30个废弃土壤样品。采用间接稀释法测定微生物群数,然后将土壤悬浮液镀在不同的选择培养基上,分光光度法测定脱氢酶活性。不同土壤利用方式下,微生物数量和活性主要受土壤ph的影响。土壤酸性反应使真菌生长更快,放线菌和固氮菌的数量更少,微生物、氨化菌和真菌的数量没有显著变化。撂撂撂撂地和有机耕作土壤的脱氢酶活性显著高于常规耕作土壤。

Effect of different soil usage on microbial properties in soils of Central Serbia
Aim of the study was to examine the effects of soil use on soil microbial properties at five locations in Central Serbia. The study included 42 samples of soil under certified organic system, 8 samples under conventional system, and 30 samples of abandoned soils. The number of examined microbial groups was assessed using the indirect dilution method followed by plating of soil suspension on different selective media, while dehydrogenase activity was measured spectrophotometrically. The number and activity of microorganisms at the tested plots primarily depended on the soil pH. The acidic soil reaction caused more rapid fungal growth and lower presence of actinomycetes and Azotobacter sp. There were no significant alterations in the number of microorganisms, ammonifiers and fungi under the specific soil use system. Significantly higher dehydrogenase activity was recorded in the abandoned soils and soils under organic systems compared to the conventional farming.
