多效硅肥是集易溶性与酸溶性于一体的硅素养分肥料。目前，在我地土壤中适量补施这类硅素肥料，对促进水稻健壮生长，达到丰产丰收具有显著效果。主要表现在以下三个方面：（一）提高了水稻结实率和产量水平试验结果表明，施用硅肥的水稻单产为607.5kg，比未施硅的亩增稻谷42.5 Multi-effect silicon fertilizer is a soluble and acid soluble in one of the silicon nutrient fertilizer. At present, the appropriate amount of such siliceous fertilizers in the soil of our country has a significant effect on promoting robust rice growth and achieving high yield and good harvest. Mainly in the following three aspects: (A) to improve the rate of rice seedling and yield test results show that the application of silicon fertilizer yield of rice 607.5kg, than the non-silicon acres of rice increase 42.5
