Seedling combined grafting device and method

Abstract

The invention provides a seedling combined grafting device and method, and relates to the field of agricultural tools. The seedling combined grafting device comprises a handheld rod, clamping plates installed on the handheld rod and a main cutter in butt joint with one end of the handheld rod. Two separating knives are correspondingly connected with one end of the main cutter through rotating pairs; the end parts of the pair of clamping plates are hinged; a clamping part is formed at the other end; the separating knives and the clamping parts of the clamping plates are oppositely arranged; thetwo clamping plates are correspondingly connected with the two separating knives through guide rods; and an included angle between the two clamping plates is changed under the action of external force, so that the two separating knives are driven to correspondingly rotate around the corresponding rotating pairs. By arranging the main cutter and the separating knives, after the main cutter cuts stock, the whole seedling combined grafting device is moved, scion cut by the cutter is driven to translate to the position above the stock cut, the clamping plates expands the cut position of the stockwhile rotate in cooperation with the separating knives, so that the scion falls to be matched with a stock connector, and the integrity and good butt joint of the scion and the stock are guaranteed.

Description

technical field [0001] The present disclosure relates to the field of agronomic tools, in particular to a combined seedling grafting device and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Seedling column grafting is the most difficult technical problem in the cultivation process of seedling column grafting seedlings. The seedling column grafting propagation technology has not been ideally solved, and the survival rate is low and unstable. The main results of current research include seedling grafting and micro-twig grafting. The methods are all indoor grafting, and there are two methods for outdoor grafting: nursery grafting and outdoor budding. Seedling column grafting is mainly to graft fruiting seedlings to disease-resistant plant larvae, and obtain nutrients in the soil through the roots of disease-resistant plants to su...

Problems solved by technology

[0004] The inventor found that the current operation process is mainly that the grower first cuts the larvae of the disease-resistant plant into pieces, and only takes the root system and the above distance as the main growth branch, and manually inserts the upper end into the blade for vertical cutting. On the contrary, the seedlings are cut to remove the root system and the above distance, and the bottom of the remaining branches is obliquely cut off to make it into a pointed shape. The shape approximately matches the cut slit on the larvae of the disease-resistant plant. Together, fix them with clips for about 10-15 days, and the branches will grow together completely and become a fruiting plant with strong disease resistance to meet the needs of growth and fruiting. However, the operation of this grafting method is very cumbersome and delicate, especially The cutting and pasting of the fitting gap and the fitting point is difficult to ensure a good butt joint between the scion and the rootstock incision; in addition, both are seedling cylinders, which are very fragile and have a very small range of movement, and excessive operation and movement can easily cause breakage; In the traditional way, the scion and the rootstock are cut separately, and then they are docked and fixed. The seedlings are small, and it is difficult to achieve effective docking and fixing of the cutting position.
