Abstract
The utility model relates to a sword. A grafting knife, includes the sword body, the sword body is connected with convex arc shape blade and arcs of recesses blade. The utility model provides a can improve the solution sword of grafting survival rate, the low problem of survival rate when the solve forms the cutting face and carries out the grafting through current linear chopper.
Description
Technical field
The utility model relates to cutter, particularly relates to a kind of grafting knife.
Background technology
Grafting refers to a part of branch or leaf cutting and cut plant corpus, and grafting, on an other strain plant corpus, makes the two become a new plant.Cut and cut branch on plant or bud scion, the plant be grafted is stock.Growth and development of plants after grafting and yielding positive results, can keep former varietal character constant.Grafting grows fast than cuttage seeding, seedling growth.The ability strengthening maladjustment environment is strong.The resistant to diseases and insects of plant is strong.From Plant Taxonomy, the nearer plant graft of affiliation more easily survives, and this is that the difference of organization structure of the plant causes.Grafting survival refers to that stock and scion face of cutting separately forms layer and mutually touches each other, and differentiate callus from the both sides face of cutting, this is the regeneration capacity that plant itself has.The callus of growing combines replenishes space, and the nutrient that stock absorbs is transported to scion by callus.Scion rudiment in the process of Callus formation, starts growth.When carrying out grafting, needs form tangent plane and realize being connected on stock with scion.The instrument in existing formation cutting face is chopper.China Patent No. be 2004200262398, Authorization Notice No. is CN2707017, name is called in the patent document of " Minitype hacking knife specified for forest " and discloses an existing chopper.Formed when grafting is carried out in cutting face by existing chopper and there is the low deficiency of survival rate.
Utility model content
The utility model provides a kind of solution cutter that can improve graft survival rate, solves and forms by existing linear chopper the problem that when grafting is carried out in cutting face, survival rate is low.
Above technical problem solves by the following technical programs: a kind of grafting knife, comprises cutter body, and described cutter body is connected with convex cutting edge and arcs of recesses cutting edge.On stock, form cutting face, stock portion by convex cutting edge during use, by arcs of recesses cutting edge scion portion inclined plane in scion, then by cutting face, scion portion and cutting face, stock portion are fit together through carrying out grafting.Which can improve bonded area, thus plays the effect improving survival rate.
As preferably, described convex cutting edge comprises the first convex cutting edge and the second convex cutting edge, and the curvature of described first convex cutting edge is less than the curvature of the second convex cutting edge.Arrange the convex cutting edge of two kinds of dimensions, use when can be applicable to the stock grafting to different bore, versatility is good.
As preferably, described arcs of recesses cutting edge and described convex cutting edge are positioned at the same side of described cutter body, and one end of described arcs of recesses cutting edge links together with described first convex cutting edge, the other end links together with described second convex cutting edge.When forming cutting face by arcs of recesses cutting edge, convex cutting edge can play and carry out spacing effect to scion, improves convenience when forming cutting face, scion portion.
As preferably, described arcs of recesses cutting edge and convex cutting edge are positioned at the same side of described cutter body.Convenience during use and safety good.
As preferably, described cutter body is removably connected with first substrate, and described arcs of recesses cutting edge is arranged at described first substrate.The convenience of mill and replacing arcs of recesses cutting edge can be improved.
As preferably, described cutter body is removably connected with second substrate, and described convex cutting edge is arranged at described second substrate.The convenience of mill and replacing convex cutting edge can be improved.
As preferably, described cutter body is provided with linear edge.Make the utility model can also be used as chopper to use.
As preferably, described convex cutting edge is positioned at the same side of cutter body with described linear edge.Safety during use is good.
As preferably, described cutter body is slab construction.Intensity is good, is not easy distortion during use.
The utility model has following advantage: can improve graft survival rate.
