【摘要】 硅酸盐细菌能释放由硅酸盐组成的岩石矿物中的磷、钾、硅等元素, 直接供给植物生长利用, 同时亦具有固氮能力。这为挖掘土壤潜在肥力、发展可持续农业提供了诱人的前景。硅酸盐细菌的特殊生理功能与适应能力必然由特殊的基因所操纵,因而有重要的理论研究价值和巨大的开发潜力。本文从形态学、解钾机理、解钾效果、解钾条件、分类地位和实际应用等6个方面对国内外近几十年来硅酸盐细菌的研究概况作一综述, 并提出其进一步研究和探索的方向更多还原

【Abstract】 Silicate bacteria may release soil potassium,phosphorus,aluminium and silicon from silicate minerals to promote plant growth,which shows wide prospect in exploitation of soil potential fertility and developemnt of sustained agriculture.The specific physiological functions and adaptive abilities of the silicate bacteria are controlled by specific genes in silicate bacterial genomes,which present its important research values and giant exploitable potentialities.The phenotype,mechanism,ability and conditions of releasing potassium,taxonomy and application of silicate bacteria are reviewed and further research directions are also proposed in this paper.更多还原
