Abstract: Effects of 3 different Fertilizers(organic fertilizers ‘chuantian’,‘shengda’ and chicken manure)in two treatments(5,10 kg·plant-1) on the main quality indexes of persimmon cv. ‘Zaohong’, such as titratable acid, Vitamin C, soluble sugar and soluble solids, were studied. The results showed that vitamin C, soluble sugar and soluble solids contents in persimmon fruits with treatments of 3 organic fertilizers increased significantly and titratable acid contents decreased obviously. These results suggested that the effect of ‘chuantian’ organic fertilizer on the fruit quality was better in this study,among the treatment of ‘chanting’ organic fertilezen 10 kg·plant-1 had the best effect.
