Effects of different silicon treatments on dry weight of rice organs (%).

Si0: no Si fertilizer; Si1: slag fertilizer applied at a rate of 187 mg plant-available Si per kg soil; Si2: slag fertilizer applied at a rate of 560 mg plant-available Si per kg soil; Si3: slag fertilizer applied at a rate of 935 mg plant-available Si per kg soil; H: slag fertilizer H, Q: slag fertilizer Q; Data are means ± SD of three replicates; mean values followed by different letters (a, b, c) are significantly different (P≤0.05).Si0：不施加硅肥；Si1：以每千克土壤187毫克植物有效硅（plant-available Si）的施用量施用硅渣肥料；Si2：以每千克土壤560毫克植物有效硅的施用量施用硅渣肥料；Si3：以每千克土壤935毫克植物有效硅的施用量施用硅渣肥料；H：硅渣肥料H，Q：硅渣肥料Q；数据为三次重复的平均值±标准差（SD）；带有不同字母（a、b、c）的平均值组间存在显著差异（P≤0.05）。
