Solubilizing micro-organisms have the biological characteristics of dissolving insoluble phosphate in soil solution into available phosphorus for plant’s absorption and utilization. It’s not only can increase the available phosphorus content in soil, enhance plant’s absorption and utilization of phosphorus, but also can promote plant’s growth. So solubilizing micro-organisms has become the focus of the practice of agriculture and forestry research in current. However, most of the research were focused on cr...
