为探索最优微生物菌肥施用量，减少化肥与农药的施用量，推动党参产业绿色发展。以党参为研究对象，采取田间试验与室内分析相结合的方法，研究了施用生物菌肥部分替代化肥对党参农艺性状、产量及品质的影响。结果表明，施用生物菌肥科微健15 kg/hm2+阵地15 kg/hm2(替代常规施肥10%)处理和生物菌肥科微健45 kg/hm2+阵地45 kg/hm2(替代常规施肥30%)处理能显著提高党参的鲜根重。与常规施肥相比，施用生物菌肥科微健45 kg/hm2+阵地45 kg/hm2处理党参显著增产37.96%；施用生物菌肥科微健60 kg/hm2+阵地60 kg/hm2(替代常规施肥40%)处理党参显著增产33.01%；施用生物菌肥科微健30 kg/hm2+阵地30 kg/hm2(替代常规施肥20%)处理党参显著增产30.66%。在试验条件下，施用菌肥处理对党参的等级和品质基本无影响。综合分析认为，生物菌肥科微健45 kg/hm2+阵地45 kg/hm2施用效果最佳。

To explore the optimum application amout of biological bacterial fertilizers, to reduce the application amout of chemical ferilizers and pesticides, and to promote the green development of Codonopsis pilosula industry. Taking Codonopsis pilosula as materials, the field experiment and laboratory analysis were conducted to study the effects of partial substitution of biological bacterial fertilizers for chemical fertilizers on agronomic characteristics, yield and quality of Codonopsis pilosula, and to research the optimal application rates of biological bacterial fertilizer, and to provide theoretical basis for the production of Codonopsis pilosula. The results showed that application of biological bacterial fertilizer Keweijian at 15 kg/ha plus Zhendi at 15 kg/ha (10% substitution of chemical fertilizers) and application of biological bacterial fertilizer Keweijian at 45 kg/ha plus Zhendi at 45 kg/ha (30% substitution of chemical fertilizers) could significantly increase the root fresh weight of Codonopsis pilosula. Compared with conventional fertilization, application of biological bacterial fertilizer Keweijian at 45 kg/ha plus Zhendi at 45 kg/ha could significantly increase the yield of Codonopsis pilosula by 37.96%. Application of biological bacterial fertilizer Keweijian at 60 kg/ha plus Zhendi at 60 kg/ha(40% substitution of chemical fertilizers) could significantly increase the yield of Codonopsis pilosula by 33.01%. Application of biological bacterial fertilizer Keweijian at 30 kg/ha plus Zhendi at 30 kg/ha(20% substitution of chemical fertilizers) could significantly increase the yield of Codonopsis pilosula by 30.66%. Under the current experimental conditions, the application of biological bacterial fertilizer had no effect on the grade and quality of Codonopsis pilosula. The comprehensive analysis showed that the biological bacterial fertilizers had the best effect at 45 kg/ha of biological bacterial fertilizer Keweijian plus 45 kg/ha of Zhendi.
