Grape sparse inflorescence is to remove weak, deformed, too dense and dislocated inflorescences. For Kyoho varieties, the inflorescence number can be determined according to the length of new shoots at the initial flowering stage in northern China, that is, the length of new shoots at the initial flowering stage is 0.4 to 0.6 m, there are no inflorescences below 0.4 m, 2 inflorescences above 0.8 m and 4 inflorescences above 65,438+0 m, leaving 65,438+0 inflorescences. At the beginning of flowering in South China, the new shoots are 0.3 to 0.6 meters long, and can leave 1 inflorescence, 2 inflorescences above 0.6 meters, and no inflorescences below 0.3 meters. Inflorescence shaping: 3-5 days before flowering, pinch off the spike tip which accounts for about 1/4- 1/5 of the inflorescence length, and pinch off the accessory spike of the inflorescence.
