硅素是否是作物生育过程中必须的营养元素,以前的研究一直没有定论,所以没有把其列为作物的必须元素。但对水稻而言,硅素却是必须元素。水稻一生中需要大量的硅素营养,是硅素作物的代表,硅素营养不足会使其产量大幅度降低。水稻通过主动方式吸收硅素, Whether or not silicon is a necessary nutrient in crop growth has not been conclusive in previous studies, so it has not been included as an essential element of crops. But for rice, silicon is an essential element. Rice needs a lot of silicon nutrition in its life, which is the representative of silicon-based crops. The lack of silicon nutrition will greatly reduce its yield. Rice actively absorbs silicon by active means,
