Grapes, one of summer’s main fruits. Fruit shape size, is an important indicator of grape appearance quality, a direct impact on their commercial and economic benefits. To cultivate large fruit-shaped grapes, in addition to select the large fruit-shaped varieties (such as Jufeng, rattan), but also to master a series of supporting cultivation techniques. Now grape cultivation techniques to promote large-scale fruit are as follows: 1. To strengthen the management of large water-fertilizer fertilizer, especially Fujiminori grapes, large amount of fertilizer required, only Shizujifei, and promptly topdressing top dressing and fertilizer, to meet Its growth and development needs. To Fujikura, for example, normal production of orchards per acre, the need to apply autumn base fertilizer 2500 ~ 3000 kg, 1500 kg spring base fertilizer. Growing season also need topdressing grape special compound fertilizer 80 ~ 100 kilograms, 30 kilometers of urea
