Yes, picking grapes is also one of the necessary measures after fruit setting. Before fruit setting, there is actually another process, that is, budding, which is carried out when grapes germinate in early spring, which also has a key impact on the later trend of grapes.

The sprouting buds are two buds. If a bud has an ear and a bud has no ear, if the ear without fruit is removed, the upper one or the weaker one should be removed, and both of them should have ears. You can choose to keep the grapes or remove the weak ones according to their vigorous growth.

After budding, when the grapes begin to set fruit, they can also be carried out by coring, which is to remove the top of the fruit-setting branch. When the fruit branches grow to more than 20 centimeters and there are seven or eight real leaves, they can be operated.

Extended data:

Tie the vines and remove the tendrils. When the new tip is about 40 cm long, it should be tied to the frame surface in time to facilitate ventilation and light transmission and avoid being blown off by the wind. General horizontal binding can alleviate the polarity of growth and control the excessive growth of new shoots, which is used for general fruiting branches and developing branches;

2-3-year-old main vines should be bent and shaped in the growth direction when bundled, so as to avoid being placed up and down or buried underground in case of breaking due to cold. Therefore, the main vine bends forward at an angle of 35 degrees with the ground, and is fixed with a wooden hook or an iron hook, and then the main vine or the sample vine is evenly tied on the frame surface at an angle of 45 degrees, so that the base of the main vine forms a "gooseneck" shape.

The binding material can be iris, straw, hemp rope or plastic strip. When binding, it should be firm and firm, but the binding rope should leave a gap for the growth of branches and vines so as not to affect the growth of thickening.
