Description

Trees of Walnut grafting knife

Technical field

A kind of grafting knife is the utility model is related to, especially in Trees of Walnut grafting knife.

Background technology

Scion grafting is that base portion is whittled into the bevel for being easy to contiguity with stock otch, is inserted into stock with one section of elite stand branch Otch in, pay attention to anvil fringe forming layer to body coincide and bondage earthing, be allowed to combine survive as new plant.Used in walnut scion grafting Scion is mostly the branch of rest period, so general all carried out in spring, and is used for the thicker stock of grafting, operates and connect slightly than bud Difficulty, but grow fast after connecing, minority then can seedling or result.The method of walnut scion grafting is a lot, the big tree grafting of Walnut in Yunnan Cortex grafting, cut-grafting, cleft grafting and side grafting are most commonly used that in production.Cortex grafting be selection stock smoothly locate it is sawed-off, from saw kerf plane Circumference selects 2~3 years full places of bark, uprightly scratches bark downwards along trunk with grafting point of a knife, depth is shown in wooden, length 6cm~10cm, then knocks bark open with knife, and wide looseness can insert scion.Fringe bar is whittled into long bevel, sees medulla, is being cut Gently cut two knives and see wooden, bevel length 6cm~10cm in face both sides.The long bevel of scion will have been cut and be close to stock xylem, insertion is drawn Open in stock bark.Lowest part opens downwards wide 0.3cm~1.0cm immediately below scion（Determined according to stock size）, long 5cm~ 10cm（Determined according to stock size）, depth is shown in xylem, and the discharge sump for taking out bark discharges water（Fluting discharges water）.With rope colligation Stock and scion are fixed, the long bevel of scion topmost will stay 1.5mm~2mm's or so to cut mouth（It is left white）, then use grafting membrane Bandage graft union, expose discharge sump during wrapping.

China Patent No. is the utility model patent of " ZL201410446395.8 ", there is provided a kind of grafting knife, its point of a knife To be trapezoidal, 0.5 centimetre of trapezoidal upper hem width, the side of the knife back has an ellipse pressure to refer to support.The grafting knife adopted the structure Operating personnel operating personnel hold handle of a knife with finger during use, flexibly carry out every scion grafting operation, and thumb is pressed in pressure and referred in support, energy Enough increase the dynamics of cutting operation.Such a design operation is flexible, but finger lifting surface area is small, due to Trees of Walnut bark and bast Portion is thicker rougher, and difficulty is higher when operating personnel cut, and easily causes thumb fatigue, is not suitable for cortex grafting operation；Exist in addition Quality softer forming layer is easily damaged to during cutting.

The content of the invention

Graft union stock bark is scratched in grafting for the Trees of Walnut grafting Common Use Tools of prior art and is knocked open slotting Point of a knife is easily broken off or is not easy knocking open stock bark and damages cambial problem when entering the stock bark of fringe bar, easy during cutting The softer cambial problem of quality is damaged to, the utility model proposes a kind of Trees of Walnut grafting knife.

Trees of Walnut grafting knife of the present utility model, it is characterised in that the grafting knife includes cutting part and grip part：Cutting It is the arc knife back on the right side of portion, lower right sets tip and sets cutting edge；Along cutting part Right vertical, two pieces of spacers are set, it is fixed Bit slice is hinged with cutting part；Cutting part upper right side both sides are set with domatic block, domatic to tilt upward；Grip part tilts and is located at Cutting part bottom-right location, seamlessly transitted with cutting part knife back side.

In use, cutting part cutting edge alignment stock is slotted downwards, the blade of projection is easily pierced into bark and bast, behaviour Grip part when making, the arc knife back facilitate human users to exert a force downwards；Spacer is embedded in bark and forming layer point protection forming layer, top Band domatic block in portion's struts bark.The long bevel of scion will have been cut and be close to stock xylem, insertion is scratched in stock bark.

As another embodiment of the present utility model, guiding gutter can be set along cutting part blade both sides.Because walnut is big It is heavier to set tree body moisture content, graft union machinery wound flows through more during grafting, unnecessary bleeding need to be guided out outside tree body to improve survival rate.

Trees of Walnut grafting knife of the present utility model is simple to operate, and design science is reasonable, can improve the survival rate of grafting, It is worth promoting in Trees of Walnut grafting work.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Wherein, cutting part 1, grip part 2, spacer 3, block 4.
