Description

Technical Field

[0001] The invention relates to the technical field of litchi growth height restriction, and in particular to a litchi growth height restriction device and a restriction method thereof. Background Art

[0002] The litchi growth height limiting device is a device that uses physical means and technical measures to limit the growth height of litchi trees in order to better manage and improve the production efficiency, picking convenience and tree health of litchi. It can help fruit farmers control the growth of trees and prevent the trees from being too tall and affecting the yield and quality of the fruit. It is also convenient for management and picking. The top of the litchi tree is often pruned regularly to remove overly long branches and control the height of the tree. Pruning can promote tree branching, improve the crown structure, increase fruit yield, and pinch the top branches of the tree to inhibit their continued upward growth and promote the tree to grow horizontally, thereby controlling the height of the tree.

[0003] Restriction devices can often only limit the height of litchi. If the height is controlled only by pruning, it will lead to uneven distribution of tree branches, resulting in unbalanced growth of the top and side branches. The tree will concentrate its strength on horizontal expansion and ignore the balanced development of the root system, which in turn affects the stability of the tree. Wider trees will affect tree management and disease and pest control, and can easily lead to insufficient light and poor air circulation in the tree, reducing fruit quality and tree health.

[0016] A limiting method for a litchi growth height limiting device comprises the following steps:

[0017] Step 1: Plant the litchi seeds in the soil, and the first restriction ring and the second restriction ring surround the branches and trunks of the litchi respectively to limit the vertical growth of the tree;

[0018] Step 2: Regularly prune the top growth point of the tree to force the tree to stop growing vertically and grow horizontally instead;

[0019] Step 3: As the servo motor starts, the height limit net is driven to move up and down during the lifting and lowering of the threaded block. The height limit net is mainly used to restrain the top of the litchi to limit the height of the tree;

[0020] Step 4: Using growth regulators can control plant growth and control water supply, which helps limit tree growth.

[0021] The present invention has at least the following beneficial effects:

[0022] 1. The present invention cooperates with the first limiting ring, silicone rod, screw, limit nut, threaded rod, threaded block, first height limiting ring and height limiting net, and the first limiting ring and the second limiting ring clamp the lychee branches respectively. Multiple silicone rods are in contact with the branches, and the silicone rods are relatively soft, which reduces the friction between the branches and the first limiting ring and the second limiting ring. The first limiting ring and the second limiting ring clamp the branches, so as to limit the longitudinal growth of the tree. After starting the servo motor, the threaded rod connected to its output shaft is driven to rotate, which also drives the threaded block to move up and down. Under the connection of the L-shaped plate, the first height limiting ring and the second height limiting ring are driven to move up and down, so the position height of the height limiting net can be adjusted. The height limiting net mainly restrains the top of the lychee to limit the height of the tree.

[0023] 2. The present invention cooperates with the reinforcement strips, wrapping rings, moving blocks, moving plates, auxiliary rods and inserting cones. After the first limiting ring and the second limiting ring are clamped on both sides of the tree trunk, the screw rod is embedded into the two reinforcement grooves. The first limiting ring and the second limiting ring are limited and fixed by means of two limit nuts and threaded sleeves at both ends of the screw rod, thereby ensuring the firmness of both. The wrapping ring is connected to the first limiting ring and the second limiting ring respectively by means of a plurality of reinforcement strips. The two wrapping rings surround both sides of the tree trunk again, thereby improving the limiting quality of the limiting device on the litchi tree trunk. The anti-slip ring is rotated clockwise in sequence, the auxiliary rod gradually moves downward, the height of the inserting cone gradually decreases, and one end of the inserting cone is gradually inserted into the soil, thereby further enhancing the stability of the first limiting ring and the second limiting ring in clamping the tree trunk.

[0024] 3. The present invention cooperates with the anti-pressure ring, height limiting ring, vertical rod, positioning strip, positioning hole and concave hole. The anti-pressure ring is made of copper alloy material, has corrosion resistance and high compressive strength, thereby extending the service life of the first height limiting ring and the second height limiting ring. The first height limiting ring and the second height limiting ring are connected by two extension rods. As the first height limiting ring moves, the second height limiting ring moves synchronously. The moving block moves up and down at one end of the vertical rod, so that the distance between the moving plate and the soil can be adjusted. After one end of the positioning strip is embedded into the concave hole and the positioning hole, the three are threadedly connected to limit and fix the convex plate and the moving block.

[0025] 4. The present invention cooperates with the waterproof coating, fiber layer, filling layer and keel layer. The waterproof coating is made of polyurethane material, which has water resistance and elasticity, prevents moisture from penetrating into the interior of the first height limiting ring and the second height limiting ring, and extends the service life of both. The fiber layer is made of carbon fiber material, which provides tensile strength and corrosion resistance, improves the external force resistance of the first height limiting ring and the second height limiting ring, and reduces the risk of denting of both. The filling layer is made of polystyrene foam, which is lightweight and heat-insulating, and does not increase the burden on the first height limiting ring and the second height limiting ring. The keel layer is made of aluminum alloy keel material, which provides structural support to ensure the stability of other layers, and has corrosion resistance and service life, further enhancing the service life of both.

[0026] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

The fiber filament layer 33 is made of carbon fiber material, which provides tensile strength and corrosion resistance, improves the external force resistance of the first height limiting ring 14 and the second height limiting ring 16, and reduces the risk of dents of the two. The filling layer 32 is made of polystyrene foam, which is lightweight and heat-insulating, and does not increase the burden on the first height limiting ring 14 and the second height limiting ring 16.
