摘　　要：土壤－植物根际磷的生物有效性研究李法云高子勤（辽宁大学生物系，沈阳１１００３６）（中国科学院沈阳应用生态研究所，１１００１５）ＳｔｕｄｙｏｆＰｈｏｓｐｈｏｒｕｓＢｉｏｌｏｇｉｃａｌＡｖａｉｌａｂｉｌｉｔｙｉｎｔｈｅＳｏｉｌ＿ｐｌａｎｔＲｈｉｚｏｓｐｈ...Phosphorus bio_availability in the soil_plant rhizosphere system was discussed in this paper. Four aspects including rhizosphere biomass, phosphatase, root exudates and method of rhizosphere phosphorus study were expounded. According to present situation of phosphorus study in this field, much more attention should be paid to the phosphorus biological and ecological process in rhizophere micro_system。
