【摘要】 硅酸盐细菌有很强的解钾能力，同时还有解磷和固氮能力。将其菌剂与土壤混合制成每克干土含10亿左右细胞的生物钾肥，用于大豆试验，结果表明生物钾肥可使土壤中有效氮、磷、钾含量提高，促进大豆植株对养分的吸收，使其干物质积累量增加，根瘤数量提高。更多还原

【Abstract】 Silicate bacterium has the strong ability of dissolving K、P and the ability of fixing N. Mixing silicate bacterium with soil, we gained the biological K fertilizer, which contains 100 million bacterium cells per gram dried soil, meanwhile we applied this fertilizer to soybean ，the result showed ：it can make the soil effective N、P、K content increased, the plant ability of absorbing nourishment improved, and the plant N、P、K content increased，so the dry matter accumulation and nodule number were increased.更多还原
