水稻是喜硅作物 ,施用硅肥对水稻有明显的增产作用已被人们所认可。但近几年来已形成一股硅肥热 ,好像所有作物和土壤施用硅肥都可以增产增收。为了进一步探索硅肥的有效施用条件和效果 ,我们进行了在有效硅含量较高的水稻田施用硅肥的肥效试验 ,为指导农民合理应用硅肥提供了 Rice is a hi-silicon crop, and the application of silicon fertilizer has obviously increased the yield of rice has been recognized by people. However, in recent years, a heat of silicon fertilizer has formed, as if all crops and soil fertilizers were used to increase yields. In order to further explore the effective application conditions and effects of silicon fertilizers, we conducted fertilization experiments on the application of silicon fertilizers in paddy fields with high effective silicon content, which provided guidance for farmers to rationally use silicon fertilizers
