Winter clipping Quadrilogy of Grape in greenhouse

A look: look at the shape of the tree, look at the tree potential, look at the variety. These intuitive factors are the basis for the formation of pruning schemes. In addition to the above three views, it also depends on the relationship between the balance of power among the various parts of the tree and the crown size of the neighboring trees. As the saying goes, "take care of the interior and take care of the neighborhood".

Second hands-on: pruning should be in order, generally removing the messy branches to form a rough frame, and then pruning the backbone branches and fruiting mother branches from top to bottom or from bottom to top. When pruning, we should pay attention to the principle of "long first, then short, more first and then less". This is mainly for the fruiting mother branch. The wound caused by pruning should be timely smeared with callus anticorrosive film to protect the growth of wound healing tissue to prevent bacterial infection from the wound. After pruning, the mother branch and backbone branch should be bound. The method of binding should be done according to the principle of flat binding of long branches, oblique binding of middle branches and no binding of short branches.

Three checks: first check the pruning of the backbone branches, such as the angle, the share of the shelf surface, etc. Then check the pruning of the mother branch of each fruit site, including the length of cutting, the position and direction of the branch group, etc.

Four cooperation: combined with the above four steps combined with hole-piercing technology to apply "Chu Hua Wang No. 1" to make the fruit trees blossom early next year, blossom more, do not fall flowers, and bear strong fruit. Two rows of holes are pierced around the tender skin of the tree body or the lower part of the main branch with a cone needle ring, with a distance of 10 cm, a distance of 2 cm and a hole diameter of 3 mm. Brush the Flower King Cream with a brush hole ring.
