摘　　要：通过盆栽试验研究探讨硅肥(沸石粉、硅酸钙、硅酸钠)及硅肥与添加剂(硫酸镁、腐殖酸)配合施用对黑龙江省水田可溶性硅的影响。结果表明:硅肥及硅肥与添加剂配施均能增加土壤可溶性硅含量。水稻在灌浆期相对于其他生长期对硅的需求有所下降,沸石粉和硅酸钙单独施用能显著增加土壤可溶性硅浓度。硅酸钠与硫酸镁配施肥效较长,与腐殖酸配施对提升土壤可溶性硅浓度的效果更显著。各处理组中硅酸钠与腐殖酸配施对土壤可溶性硅浓度提高最显著。A pot experiment was conducted to study the change of soluble silicon in paddy field through using sili- con fertilizer （zeolite powder, calcium silicate, sodium silicate） and silicon fertilizer with additives （magnesium sul- fate, humic acid） applications in Heilongjiang province. The results showed that the silicon fertilizer and silicon fer- tilizer with additives can increase the soluble silicon concentration in the soil. The rice needs a few silicon in the filling stage than other growing stages. Zeolite powder and calcium silicate fertilizer could significantly increase soil soluble silicon concentration alone. The effects of sodium silicate with magnesium sulfate fertilizer is longer. The effects of sodium silicate with humic acid is more prominent to improve the soil soluble silicon concentrations. Among treatment groups, the sodium silicate with humic acid increases soluble silicon concentrations significantly.
