| 摘 要： | 考察巨大芽孢杆菌JD-2对有机磷、无机磷的降解效果,比较巨大芽孢杆菌JD-2、乳酸芽孢杆菌、枯草芽孢杆菌对土壤有效磷化的作用差异。研究不同浓度的巨大芽孢杆菌JD-2对土壤有效磷化的作用效果。结果表明:巨大芽孢杆菌JD-2具有很强的降解有机磷、无机磷的能力,有效磷含量分别为对照组的25倍、22倍。巨大芽孢杆菌JD-2在土壤中的解磷效果最好,土壤有效磷含量由19.0 mg/kg增至34.5 mg/kg。不同浓度的巨大芽孢杆菌JD-2在土壤中均具解磷效果,接入土壤起始浓度106CFU/g最适宜。

| Abstract: | To research on degradation effect of organic phosphorus and inorganic phosphorus of Bucillus megaterium JD-2,the differences of soil available phosphorus among Bucillus megaterium JD-2,Lactic acid bacillus,Bacillus subtilis was compared.Effect of different concentration of Bucillus megaterium JD-2 on soil available phosphorus was studied.The results indicated that Bucillus megaterium JD-2 had a strong degradation ability of organic phosphorus and inorganic phosphorus.The available phosphorus content was 25 times and 22 times as much as the control group.Bucillus megaterium JD-2 had the best degradation phosphorus ability and soil available phosphorus content increased from 19.0 mg/kg to 34.5mg/kg.In the soil,different concentration of Bucillus megaterium JD-2 had the effect on dissolving phosphorus,but the best initial concentration was 106CFU/g in the soil. |
