Abstract

In order to reduce the acid content of Huangguogan and improve the fruit quality, this experiment used Huangguogan as the test material and designed 7 organic manure treatments for its four key fertilization periods. The internal and external quality of each treated fruit was measured and analyzed. The test results are as follows: Different organic fertilizers can improve the internal and external quality of Huangguogan. In addition to no significant effect on the fruit shape index, all indicators are significantly better than the control. The use of bio-organic fertilizer as the base fertilizer treatment 3 and treatment 6 soluble sugar increased by 9.3% and 22%, and the titratable acid (TA) decreased by 30.85% and 26.60%. Meanwhile, the sugar-acid ratio increased by 56.82% and 66.55%. The effects of increasing sugar and reducing acid were most obvious. It can be applied to the actual production industry of Huangguogan.
