摘要：The effects of soil testing formula fertilizer on fruit quality of the Kyoho grape was studied by using 4-year-old Kyoho grape as the test material. The results showed that, scientific and reasonable formula fertilizer could improve the quality of grape comparing with conventional fertilizer, evidently increase the single grain weight of fruit and single ear weight of fruit, and also increase the vitamin C content, sugar-acid ratio and solid acid ratio. On the other hand, it could decrease titratable acid content, and slightly increase vertical and horizontal diameters, but had little effect on pericarp color.
