补充资料：硅肥
| 硅肥 silicon fertilizer 具有硅标明量的肥料。主要用于水稻，有时也用于甘蔗、竹等。施入土壤后能为植物提供硅养分，提高土壤中有效硅的供应水平。属碱性物质，兼有提高土壤pH值的作用。多用作基肥。田间施用的硅肥主要是含硅酸盐的工业废渣。施用硅肥的效果与土壤中硅的含量和形态有关。土壤中二氧化硅的含量虽然占土壤重量的20％～80％，但绝大部分呈结晶态，不能被植物吸收利用。土壤中的有效硅，即能溶于pH值为4的醋酸缓冲液的硅，其含量因土壤的成土母质类型而异。凡成土母质中含易风化矿物多的土壤有效硅含量较高；发育于花岗岩、石英砂岩、凝灰岩风化物上的土壤含硅量较低；质地较轻、土层较薄、淋溶强烈、酸性较强以及有机肥料用量少的土壤，其有效硅含量也低。缺硅的水稻土多为低pH或砂质土壤。水稻茎叶中的二氧化硅含量不及茎叶干重的10％时，即可视为缺硅，需要施用硅肥。 |
