一、硅的生理作用 1、水稻植株内硅含量与分布情况 据以往的研究,发现在植物体内硅的含量分布具有:种间差异大,植物各部分分布不均匀和受环境条件影响大三个特点。一般认为单子叶植物比双子叶植物硅含量高,其中单子叶植物中的禾本科植物又比其它植物高。水稻是一个代表性的喜硅植物,它可吸收大量的硅,且植物体内硅的含量特别高。如茎叶 First, the physiological role of silicon 1, the silicon content and distribution of rice plants According to previous studies, found that the distribution of silicon in plants with: a large difference between species, plant parts of the uneven distribution and environmental conditions by the impact of three Features. Monocotyledons are generally considered to be higher in silicon content than dicotyledons, of which monocots are higher than other plants. Rice is a representative hi xi plant, which can absorb large amounts of silicon, and plant silicon content is particularly high. Such as stems and leaves
