Blueberry is an important agricultural crop with high nutritional, health, and economic value. Despite the well-studied blueberry cultivation methods and soil requirements, little is known about how beneficial bacteria function in organic blueberry cultivation systems and their effects on acidic soils. In this study, a single bacteria JC65 and three biocontrol bacteria consortiums containing JC65 were applied to organic system. The effect of bacteria to blueberry growth, yield, fruit quality, and soil quality was investigated. A consortium of three mixed ( JC65, HS10 and 7ze3) showed the highest growth improvement efficiency. The bacterial inoculation increased blueberry leaf chlorophyll content, net photosynthetic rate by 21.50%, 13.21% at 30 days, and increased average plant height by 2.72% at 69 days. Compared with the control, the inoculated plants showed an increased yield of 14.56%. Interestingly, blueberry fruit quality was also improved with supplement of the bacterial consortium. Fruit anthocyanin, soluble sugar, vitamin C, soluble solids, and soluble protein content were increased by 5.99%, 4.21%, 17.31%, 2.41%, and 21.65%, respectively. Besides, beneficial bacterial consortium also enables sustainable agriculture by improving soil ammonium nitrogen and organic matter by 3.77% and 2.96% after blueberry planting. In conclusion, the combination of beneficial bacteria showed a synergistic activity in organic system to promote the blueberry yield, fruit quality, and soil nutrient preservation.
蓝莓是一种具有高营养、健康和经济价值的重要农作物。尽管蓝莓的种植方法和土壤要求已得到充分研究，但对于有益细菌在有机蓝莓种植系统中的作用及其对酸性土壤的影响却知之甚少。在本研究中，将单一细菌JC65和包含JC65的三个生物防治细菌组合应用于有机系统。研究了这些细菌对蓝莓生长、产量、果实品质和土壤质量的影响。由三种细菌混合而成的组合（JC65、HS10和7ze3）显示出最高的生长促进效率。接种细菌后，蓝莓叶片叶绿素含量、净光合速率在30天时分别提高了21.50%、13.21%，在69天时平均株高增加了2.72%。与对照相比，接种植物的产量提高了14.56%。有趣的是，添加细菌组合后蓝莓果实品质也得到了改善。果实花青素、可溶性糖、维生素C、可溶性固形物和可溶性蛋白质含量分别提高了5.99%、4.21%、17.31%、2.41%和21.65%。此外，有益细菌组合还通过在蓝莓种植后将土壤铵态氮和有机质分别提高3.77%和2.96%，实现了可持续农业。总之，有益细菌的组合在有机系统中表现出协同活性，可促进蓝莓产量、果实品质和土壤养分保持。
