For grapes, Thidiazuron can be used to pull ears, preserve flowers and fruits, and enlarge fruits. Pull ears about 10 days before flowering, add 30ml to 50kg of water, and 15-20 days after flowering after physiological fruit drop, the fruit will swell, use a concentration of 30ml/bottle and add 10kg of water.

Whole ears and thinned fruits. When the inflorescence is elongated, several spikelets on the shoulders are also elongated. After fruit setting, cut off some fruit grains from the overly long spikelets to make the spikes form a cone or cylindrical shape; for varieties with accessory spikes, cut off the accessory spikes before flowering; The tips of the ears should be pinched off before flowering; after fruit setting, the fruit should be thinned lightly to remove small fruits and reduce the amount of fruit thinning.
