Abstract

The aim of the study was to evaluate the impact of silicon (Si) and calcium (Ca) added to the substrate (perliteor its mixture with peat) used in soilless strawberry cultivation on the number of different groups of microorganisms in the substrate. Research was conducted on a farm located in southern Poland in which soilless cultivation of strawberries in gutters, under covers, with an irrigation system was carried out. The microbiological analyzes were performed by serial dilution method. The analyzes included determination of the total number of bacteria, actinobacteria, fungi and aerobic atmospheric nitrogen assimilators of the Azotobacter genus. In this work, we showed that the concentration of microorganisms associated with the cultivation substrate may be influenced by the presence of silicon and calcium added to the composition of the substrate. Correlation analysis showed that the addition of Si + Ca to the substrate affects increase in the total number of bacteria in the substrate. The obtained results confirm that the cultivation substrate can be modified in such a way that it is more conducive to the multiplication and survival of bacteria associated with the substrate.

硅钙添加剂对草莓无土栽培基质中微生物群生长的影响

本研究的目的是评估在无土草莓栽培中使用的基质（珍珠岩或其与泥炭的混合物）中添加硅（Si）和钙（Ca）对基质中不同微生物群数量的影响。这项研究是在波兰南部的一个农场进行的，该农场在排水沟、覆盖物和灌溉系统中进行了草莓的无土栽培。微生物分析采用连续稀释法。分析包括对固氮菌属细菌、放线菌、真菌和需氧大气氮同化物总数的测定。在这项工作中，我们表明，与培养基质相关的微生物浓度可能受到添加到基质成分中的硅和钙的存在的影响。相关分析表明，在基质中添加Si+Ca会影响基质中细菌总数的增加。所获得的结果证实，可以对培养基质进行改性，使其更有利于与基质相关的细菌的增殖和存活。
