In this experiment, Huangguogan in Shimian County was selected as the experimental material, and the effects of different treatments on the fruit quality of Huangguogan were studied by mulching treatments with black film, straw, horticultural cloth and river sand. The results of this study showed that the application of chelated iron to the roots under different mulching materials could significantly improve the fruit quality, and the application of chelated iron to the roots under different mulching materials had different effects on fruit quality. The river sand mulching treatment had the highest single fruit weight, vertical and horizontal diameters, while CK had the lowest one. The four mulching treatments all increased the contents of total soluble solids, soluble sugar and sucrose. The river sand mulching treatment had the highest contents, which were 13.96%, 13.09 and 6.93 g.100 mL-1, respectively. There were significant differences in the titratable acid, vitamins C and sugar-acid ratio between the different mulching treatments, and the river sand mulching treatment had the highest effect. In general, the river sand mulching treatment had the best effect on promoting fruit quality, and plastic film mulching treatment had the worst effect.
