硅酸钠以单体形式或聚合物形式溶解在水中；研究了两种形式的硅酸钠水溶液对玫瑰白粉病和小型玫瑰根腐病的影响。将两种形式的硅酸钠水溶液施用于微型玫瑰的根部。使用硅酸钾水溶液作为对照并与硅酸钠水溶液的效果进行比较。聚合物硅酸钠水溶液是对抗白粉病和根腐病最有效的治疗方法。此外，在体外没有观察到硅酸盐溶液对玫瑰根腐病病原菌螺旋腐霉的抑制作用。聚合物硅酸钠处理的微型玫瑰根部硅含量显着高于单体硅酸钠处理的植株。总之，聚合物形式的硅酸钠对小型玫瑰的白粉病和根腐病具有抑制作用。关键词：Podosphaera pannosa，腐霉，微型玫瑰，聚合物和单体硅酸钠。
Sodium silicate was dissolved in water in either a monomer form or polymer form; the effects of both forms of sodium silicate aqueous solution on rose powdery mildew and root rot diseases of miniature rose were examined. Both forms of sodium silicate aqueous solution were applied to the roots of the miniature rose. Potassium silicate aqueous solution was used as a control and was compared to the effect of sodium silicate aqueous solution. The polymer sodium silicate aqueous solution was the most effective treatment against both powdery mildew and root rot diseases. Moreover, no inhibition effects of silicate solutions were observed in vitro on Pythium helicoides, the causal pathogen of rose root rot disease. The silicon contents in the roots of the miniature rose treated with polymer sodium silicate were significantly greater than that in plants treated with monomer sodium silicate. In conclusion, the suppressive effects of sodium silicate in the polymer form were confirmed against powdery mildew and root rot diseases of the miniature rose. Key words: Podosphaera pannosa, Pythium helicoides, miniature rose, polymer and monomer sodium silicate.
