硅酸盐细菌在农业中应用的研究动态

硅酸盐细菌能将土壤中难溶性的钾、磷等元素转化为可溶性,还能固氮,同时其代谢产物能抑制植物病原菌生长、改善土壤肥力。施用硅酸盐细菌与化学钾肥相比,农作物增产效果好、成本低、不污染环境,具有很高的经济、生态价值。本文从生物学特性、对土壤中硅酸盐类矿物的分解作用及其机理、在农业生产中的应用效果等方面对国内近年来硅酸盐细菌的研究动态作一综述,并指出了其中存在的问题和发展趋势。

The Study Dynamics of Silicate Bacteria Applied to Agriculture

Silicate bacteria can transform the indissoluble potassium,phosphorus ect elements of siols into soluble,and also can fix nitrogen.It's metabolite can restrain the crop's pathogen growing and improve soil's fertilizer.Comparing to the chemical potash fertilizer,the effect that Silicate bacteria make the crop increace production is superior and the cost is lower.That doesn't pollute the environment,and is of greatly economic and ecological value.From the biological characters,releasing effect to minerals of soils and mechanism,the effect of appling to agricultural production ect aspects,the study dynamics of Silicate bacteria of recent years is reviewed.The existent question and trend of development are pointed out.
