近年来有关试验资料表明,在水稻上施用硅、钾肥有抗病增产效应,特别是随着产量不断提高,氮、磷化肥用量日增,士壤中钾素养分相应缺乏.硅素也有所不足,同时,土壤有变酸趋势,为此,施用硅、钾肥料就显得更为重要。故应广辟硅、钾肥源,以满足作物对硅、钾元素的要求。目前施用的硅肥为碱性 In recent years, the experimental data show that the application of silicon and potassium on rice has the effect of disease-resistant and yield-increasing, especially with the continuous increase of production, the increasing use of nitrogen and phosphorus fertilizers, the corresponding lack of potassium nutrients in the soil, At the same time, the soil has sour tendency, therefore, the application of silicon, potassium fertilizer is even more important. Therefore, silicon and potassium sources should be widely used to meet the requirements of crops for silicon and potassium. The current application of silicon fertilizer is alkaline
