First, the ear with poor fruit setting will be thinned out, the weak branches will not produce ears, and the middle branches will have strong branches 1 ear. For larger panicles, 2 ~ 3 branches are removed from the base, and 14 ~ 16 small branches are reserved from bottom to top, so that the panicle is deformed into a cylinder. After fruit setting, fruit thinning and heading are carried out until the grapes grow to the size of soybeans, and small, abnormal and over-dense fruit grains are thinned. According to the characteristics of varieties, choose the appropriate number of grains left. Take Kyoho as an example, there are 30 ~ 40 fruits per ear, with an average grain weight of 12 ~ 13g, an ear weight of 400~500g and a yield of 650~750kg per 667 square meters.
