硅酸盐细菌俗称钾细菌 ,它具有把土壤中难溶解钾溶解成有效钾、产生某些植物激素以及由于大量产生细菌多糖从而改善土壤持水性等功能 ,对农作物的营养是一种复合作用[1] 。它成本低 ,无污染 ,符合现代可持续农业发展的要求。目前 ,它对农作物增产的作用已有报道[2 ] ,但未见它 Silicate bacteria, commonly known as potassium bacteria, have a complex effect on crop nutrition due to their ability to solubilize insoluble potassium in the soil into available potassium, produce certain plant hormones, and improve soil water retention due to the production of bacterial polysaccharides in large quantities [ 1] . It is low cost, pollution-free and meets the requirements of modern sustainable agriculture. At present, its role in increasing crop yields has been reported [2], but it has not been seen
