摘　　要：在不同温度和不同烘干时间条件下,研究了活化剂对石英砂中硅的活化效果及其肥效。研究表明:活化效果是活化剂用量、烘干温度和烘干时间的综合作用结果;在现有试验条件下,活化剂添加质量分数为10%、于200℃下烘干1 h的效果最好,3次水溶性硅的浸提总量是未活化石英砂的685倍;活化石英砂可提高盆栽水稻和玉米的生物量、植株的吸硅量、土壤有效硅含量。The activation effect of activator on silicon in arenaceous quartz and its fertilizer effect under conditions of different temperatures and different drying times are researched .Research results show that activation effect is the combined result of quantity of activator , drying temperature , and drying time , and under current experimental conditions , when additive quantity of activator is 10%（mass fraction）, temperature is 200 ℃, drying time is 1 h, the effect is the best, the total extraction quantity of 3 times of water soluble silicon is 685 times of that of unactivated arenceous quartz;activated silicon fertilizer can promote biomass and silicon uptake and of potted rice and maize available soil silica content .
