1、 How to prune flowers

1. Coring treatment: before flowering, the newly grown branches and vines shall be coring treatment, and the removed part is generally about 10 cm long. The tendrils should be removed during its growth, which can save nutrient consumption and facilitate the growth of branches and vines and later fruits. All lateral vines should also be treated when picking the heart

2. Remove flower ears: the nutrition of grapes is limited. If there are too many flower ears, remove them in time, so that the remaining ears can absorb enough nutrients and maintain better growth. Generally, only one inflorescence should be left for each fruit bearing branch, and the rest should be removed. 10 days before flowering, cut off the lateral spikelets and spikelets on the side, and only keep 13-20 spikelets in the middle. If you don't prune it, it will not bear all the fruit if it grows too dense. On the contrary, it will consume a lot of nutrients

2、 How to trim after the results

After the flowers fall, the fruit seeing treatment is carried out, about a week after the flowers. At this time, the grape grain is about the size of mung bean. The fruit grains with weak growth, the fruit grains in the ear and the fruit grains on the top of the ear should be cut off. Finally, 40-120 fruit grains should be left for each ear, so that the weight of the grape cluster after ripening can be stabilized at 300-1200 grams, which can ensure the uniformity of the ear. In addition, when the ear grows to 15-20 cm, cut off 1 / 4 of the inflorescence tip, which can save nutrients, facilitate the growth of fruit grains and better achieve high yield
