To improve the phosphorus utilization efficiency and medicinal quality of the traditional Chinese medicinal herb var. , three inorganic phosphorus-solubilizing bacteria strains ( Y1-1, Z6-1, and Z3-4) were inoculated individually and in combination into the rhizosphere soil of var. in a greenhouse pot experiment. At the late growth stage, the contents of total and inorganic phosphorus in the rhizosphere soils, as well as the total phosphorus and six steroidal saponins in the plants, were measured. The proportion of inorganic phosphorus in rhizosphere soils of treatment groups increased by 9.8330.43%. The content of effective phosphorus form Ca-P in the rhizosphere soils of treatment groups increased by 50.81328.37%. Inoculation with (S2, S3, and S6) significantly increased total steroidal saponin content in plants by 9.14%, 10.64%, and 16.58%, respectively. An antagonistic effect was observed when multiple bacterial strains were inoculated together. Thus, mixed inoculation was less effective than single-strain inoculation in improving rhizosphere soil phosphorus structure. In conclusion, inoculation with inorganic phosphorus-solubilizing bacteria could enhance phosphorus availability in rhizosphere soil and improve medicinal quality of var. . These findings provide a basis for efficient phosphorus resource utilization and sustainable cultivation to enhance medicinal plant quality.
为提高中药材[具体品种]的磷利用效率和药用品质，在温室盆栽试验中，将三株无机磷解细菌菌株（Y1-1、Z6-1和Z3-4）单独及组合接种到[具体品种]的根际土壤中。在生长后期，测定了根际土壤中总磷和无机磷的含量，以及植株中的总磷和六种甾体皂苷含量。处理组根际土壤中无机磷的比例提高了9.83%30.43%。处理组根际土壤中有效磷形态Ca-P的含量提高了50.81%328.37%。接种[具体菌株组合]（S2、S3和S6）分别使植株中总甾体皂苷含量显著提高了9.14%、10.64%和16.58%。当多种菌株一起接种时观察到拮抗作用。因此，在改善根际土壤磷结构方面，混合接种不如单菌株接种有效。总之，接种无机磷解细菌可提高根际土壤磷有效性，改善[具体品种]的药用品质。这些研究结果为高效利用磷资源和可持续种植以提高药用植物品质提供了依据。
