大量研究结果表明:硅对水稻、麦类等许多作物的生长发育有利,尤其是水稻,属典型的需硅酸作物,每生产500公斤稻谷,需要吸收87～100公斤硅。国外已把“硅”作为一种化肥大量施用,我国近年来在部分地区施用硅肥,也收到了良好增产效果。硅对作物生长发育的影响:(1)硅是植物细胞壁的组成成分,影响着细胞的分裂;施用硅肥能增强作物的机械和抗倒伏能 Numerous research results show that silicon is beneficial to the growth and development of many crops such as rice and wheat, especially rice, which is a typical silicic acid crop. It needs to absorb 87-100 kilos of silicon for every 500 kilograms of rice produced. Foreign countries have already used “silicon” as a kind of chemical fertilizers in large numbers. In recent years, China has applied silicon fertilizer in some areas and also received good yields. Effects of silicon on crop growth and development: (1) Silicon is a component of plant cell wall that affects cell division; application of silicon fertilizers enhances the mechanical and lodging resistance of crops
