盆栽及田间试验结果表明，硅酸盐菌剂对土壤钾的释放、大豆对钾的吸收具有一定的促进作用。田间小区试验硅酸盐菌剂22．5kg/hm2用量大豆增产效果较好，比不施硅酸盐菌剂增产8．0％，硅酸盐菌剂配合肥料钾增产效果更佳。
The results of potted and field experiments showed that the release of potassium by soil silicate and the absorption of potassium by soybean were promoted. Field trials of silicate bacteria 22.5kg / hm2 field soybean yield is better, than the non-silicate bacteria yield 8.0%, silicate bacteria agent with fertilizer potassium yield better.
