采用蒋柏藩-顾益初提出的石灰性土壤无机磷形态分级方法，研究不同剂量生物菌剂对种植年限为25年的蔬菜保护地耕层土壤无机磷活化的影响。结果表明，生物菌剂可以增加Ca2-P、Al-P、Fe-P含量，降低土壤中Ca10-P、Ca8-P含量，对O-P含量影响不明显，证明生物菌剂可以促进土壤中的磷素向易被作物利用的状态转化，减缓向缓效态、难溶态的转化。

Jiang-Gu inorganic phosphorus fractionation method was used to study the phosphorus status, to study different doses biological bacterium agent activated inorganic phosphorus of the soil cultivated vegetable 25 years.The results showed that biological agents could increase the content of Ca2-P, Al-P, Fe-P, reduce the content of Ca10-P, Ca8-P, while do not affect the content of O-P. Biological bacterium agent can promote soil to plant available phosphorus normal transformation.
