通过探究复合微生物菌液和山崎营养液减量配施对水培黄瓜产量、品质的影响，创新水培黄瓜优质高效生产技术。以黄瓜甘丰袖玉为试材，探究全量和减施20%山崎营养液分别与0.5%、1.0%、1.5%复合微生物菌液配施对黄瓜产量、果实品质的影响。结果表明，添加复合微生物菌液可以提高产量，全量山崎营养液与1.0%复合微生物菌液配施处理的黄瓜产量最高，为68 890.5 kg/hm2，黄瓜果实品质最佳，维生素C含量为4 339.1 mg/kg、可溶性蛋白质含量为3.08 mg/g。综合比较，添加复合微生物菌液可有效提高黄瓜产量和果实品质，以添加1.0%复合微生物菌液的全量山崎营养液的增产提质效果更优。

In order to investigate the effects of reduced application of composite microbial bacterial solution and Yamazaki nutrient solution on the yield and quality of hydroponic cucumber so as to innovate high-quality and efficient production technology for hydroponic cucumbers. Cucumber Ganfeng Sleeve Jade was used as the material, the hydroponic experiment was conducted to investigate the effects of full and 20%reduction in application ofYamazaki nutrient solution combined with 0.5%, 1.0% and 1.5% composite microbial fungi solution on the yield, fruit quality, respectively. Results showed that the addition of composite microbial fungi solution could increase the yield, and the treatment of full Yamazaki nutrient solution with 1.0% composite microbial fungi solution had the highest cucumber yield, which was 68 890.5 kg/ha, and the fruit quality was the best, vitamin C content was 433.91 mg/100g, soluble protein content was 3.08 mg/g. In conclusion, the addition of compound microbial fungi solution can improve the yield and fruit quality of cucumbers, adding 1.0% compound microbial fungi solution in full Yamazaki nutrient solution showed the best effect in yield and quality improvement.
