介绍并讨论了国内外有关土壤硅、磷两种元素交互作用的研究动态与进展。硅、磷元素在植物体内的交互作用并非由于硅在生理上代替了植物对磷的需要,而是由于硅的存在降低了过量铁、锰、铝等金属离子的毒害,从而改善了植物的磷素营养。硅、磷元素可以相互促进肥效,提高各自的生物利用率。二者在土壤中存在着竞争性吸附关系,其中土壤对磷的吸附结合能更大。磷的施用不仅降低了土壤对硅的吸附,而且增加了硅的解吸。
This paper introduces and discusses the research progress and development of the interaction between soil silicon and phosphorus at home and abroad. The interaction between silicon and phosphorus in plants is not due to the fact that silicon physically replaces the need of phosphorus for plants but rather reduces the toxicity of metal ions such as excess iron, manganese and aluminum due to the presence of silicon, thus improving plant phosphorus Vegetarian nutrition. Silicon and phosphorus can mutually promote fertilizer efficiency and improve their bioavailability. The two in the soil there is a competitive adsorption relationship, in which soil adsorption of phosphorus can be greater. Phosphorus application not only reduces the soil adsorption of silicon, but also increases the desorption of silicon.
