Description

A kind of special grafting knife of Pinus massoniana Lamb

Technical field

This utility model belongs to field of forestry, is specifically related to a kind of special grafting knife of Pinus massoniana Lamb.

Background technology

Grafting, one of artificial nutrition propagation method of plant.I.e. branch or the bud of a kind of plant, it is grafted onto on stem or the root of another kind of plant, makes be connected together two parts grow up to a complete plant.The mode of grafting is divided into scion grafting and bud grafting.The cambium layer that should make scion and stock during grafting is combined closely, to guarantee that scion survives.The branch connected or bud, be called scion, the plant connect, and is called stock or platform wood.Typically select the Seedling of 2 to 4 buds of tool during scion, become top or the top of plant after grafting, after stock grafting, become the root system part of plant.

For cutting the cutter of scion and stock when grafting knife is grafting, existing grafting knife is typically made up of handle of a knife and blade.

Applicants have invented a kind of new Pinus massoniana Lamb grafting, it is referred to as extension cambium layer grafting, this method can improve graft survival rate, and its main points are, when cutting stock, only cut the crust of stock, retaining complete stock cambium layer, cutting width wants suitable with the diameter of scion, so that forming the contact of line dough-making powder between scion and the cambium layer of stock, thus time the cambium layer of scion and stock cambium layer can 100% contact, increase graft survival rate.This kind of grafting method uses traditional grafting knife the most inconvenient, needs three cuttves, the most horizontal partial application, perpendicular again cut two cuttves and could realize, although graft survival rate can be improved, but grafting efficiency is on the low side, it is thus desirable to relate to a kind of special cutter, quickly realize the extension cambium layer grafting of Pinus massoniana Lamb.

Utility model content

This utility model purpose is to provide a kind of special grafting knife of Pinus massoniana Lamb, solves the problem that existing cutter is inefficient when using extension cambium layer grafting grafting Pinus massoniana Lamb.

The technical solution of the utility model is: a kind of special grafting knife of Pinus massoniana Lamb, including handle of a knife and the blade being fixed on handle of a knife front end, blade back is provided with rossing hook, described rossing hook generally lamellar, its one end is vertical with blade back to be fixed, the other end forms hook portion to curving, and described hook portion has cutting edge.

Further, the quantity of described rossing hook is 2-4 root.

Further, the width of rossing hook cutting edge is different.

Further, the width of described rossing hook cutting edge is 0.5-1cm.

When using grafting knife of the present utility model cutting stock crust, make the vertical stock of grafting knife, with the horizontal partial application on stock of the cutting edge of rossing hook, being flipped up by grafting knife the most gently, can hang up stock crust, then pull down, the most removable crust, retains complete cambium layer.

This utility model compared with prior art has the advantage that

This utility model is by adding special rossing hook structure on the basis of existing common grafting cutter, normal cutting function can not only be provided, moreover it is possible to quickly strike off the crust of Pinus massoniana Lamb, retain the cambium layer that stock is complete, realize extension cambium layer grafting, significantly improve grafting efficiency.

Fig. 1 is the structural representation of grafting knife of the present utility model；

In figure, reference is: 1-handle of a knife, 2-blade, 3-rossing hook.

Detailed description of the invention
