对我省３种硅无素缺乏的砂壤土稻田施用两种硅肥的试验结果表明，施硅增产达显著水平以上的占８３．３３％，以施硅量为Ｎ∶ＳｉＯ２＝１∶０．８４的增产效果最佳，其中水溶性硅肥的增产作用又明显优于枸溶性硅肥。施硅可提高土壤的供氮能力，增加水稻对氮磷的吸收；施硅可使水稻株型挺拔，同时可抑制水稻的蒸腾作用，从而提高光能利用率；施硅还加强了水稻茎秆表皮硅质化，增强了水稻的抗病虫害、抗倒伏等抗逆性能。
The results of applying two kinds of silicon fertilizers on three types of sandy loam paddy soils lacking in silicon in our province showed that the yield of silicon fertilization reached 83.33% above a significant level, and the amount of silicon applied was N: SiO2 = 1: 0. 84 yield the best effect, including the role of water-soluble silicon fertilizer yield significantly better than citric acid soluble silicon fertilizer. Silicon application can improve soil nitrogen supply capacity and increase nitrogen and phosphorus absorption of rice; silicon can make plant type tall and straight, at the same time can inhibit rice transpiration, thereby increasing the utilization of light energy; silicon also strengthen the rice stem Epidermal siliconization, enhanced rice resistance to pests, lodging and other anti-retrograde performance.
