In general, only 65,438+0 inflorescences are left in each fruiting branch, and thinning is carried out according to the principle of removing small inflorescences and retaining large inflorescences. Inflorescence shaping can make the ear compact and beautiful, and at the same time, it can save nutrients, from pre-flowering 1 week to early flowering. Remove the accessory spike, shoulder spike and spike tip to shape the inflorescence, that is, first remove the accessory spike, remove the 1-2 branch at the base of the spike axis and cut off the tip of the inflorescence, with a total length of about 1/4 spike length. Generally, the number of grains per panicle of scarlet is controlled between 100- 120 spikelets. Shake the ear after withering and before thinning the fruit, so that the ear with poor fertilization will fall off as soon as possible, and at the same time, all the grape ears hanging on the iron wire and in the cracks of the branches will fall below the shelf surface, so that they will grow naturally.
