Description

The monolateral cortex grafting supporting technology of Chinese torreya

Affiliated technical field

Patent of the present invention relates to a kind of new grafting method of Chinese torreya and guarantees that this method achieves success cuts fringe and the supporting protective condition of two classes thereof.This method is easy to operate, and is with low cost, and the survival rate height is suitable for multiple situation and uses, and also is easy to penetration and promotion.Strict method operation of illustrating by this patent is even new hand's grafting also can have the graft survival rate more than 90%.

Background technology

The Chinese torreya grafting is the important step during the Chinese torreya improved variety is produced.No matter be the transformation of wild wooden Chinese torreya, or the cultivation of ground, Chinese torreya garden grafting, grafting all wanted.At present, the grafting of Chinese torreya still has certain mysteriousness.Even in the old producing region of Chinese torreya, graft technology is not popularized yet.Outstanding advantages such as growth is fast because the Chinese torreya seedling has, resistance, progressively formed the development model of " planting seedling earlier; treat that long the remarrying after certain rugosity of seedling connects the replacing breeding " in vast Chinese torreya producing region, so, press for find a kind ofly not only popularized easily, grafting effect but also good method.

2003, we carried out extensive experimentation, and the result proves that monolateral cortex grafting can become a kind of important method of Chinese torreya grafting.It is not only applicable to the grafting of general 2-3 raw Chinese torreya seedling, can be applied to the original place or the strange land transformation of wild Chinese torreya yet, even can also be used for the collar position grafting in annual strong sprout.As long as grafting enemy in season, the fringe bar is suitable, catches in operation and cuts fringe, protection two big links, just can guarantee 90% graft survival rate.

Description of drawings

The cutting position and the trend of accompanying drawing 1, scion

1, cutting edge initial point 12, cutting edge initial point 23, haircut are represented the edge of a knife trend of grafting knife

Required stock: single-edge blade, soft plank.

Adopt the draw cut method to cut scion.Grasp two angles.The one, the angle of blade cutting edge and fringe bar (is controlled between 5-10 °, angle is more little, bevel is long more), the 2nd, the angle that blade face and fringe bar keep between the position extended surface (being fill plate generally speaking) (is controlled between 5-10 °, angle is big more, the length difference of bevel both sides is apart from big more, and the stability after the grafting binding is poor more).Make the both sides of the wedge shape bevel of the fringe bar of cutting, Yi Bian long, thick slightly slightly, another side is short, thin slightly slightly.The length on long limit is not less than 1.5 centimetres, and the gap on length both sides is not more than 5 millimeters.

The scion that accompanying drawing 2 adopts the draw cut method to be whittled into

1, bud 2, leaf 3, cortex 4, xylem 5, bevel total length greater than the gap of 1.5cm 6, webbing and featheredge end less than 0.5cm

Accompanying drawing 3 stocks cutting schematic diagram

Embodiment:

One, conventional grafting

1, selects the fringe bar

Conventional grafting is meant that mainly 2-3 gives birth to the grafting of seedling, must select for use sturdy branch as scion.Generally speaking, the rugosity of fringe bar base portion should be greater than 2.5 millimeters.

If the annotinous branch position is thinner, also can utilize the grafting of biennial position.

2, fringe bar cutting

Adopt draw cut method cutting scion.Specific practice is: remove earlier the leaf at cutting position on the fringe bar, holding the fringe bar with left hand again has leaf site, and branch is not had leaf site be close to plank and give suitably fixing.The right hand is held cutter, the angle of blade cutting edge and fringe bar and the angle between blade plane and the fill plate all is controlled between 5-10 °, by downward draw cut the most suitable for reading, cut a side, after changing position and angle, inclination direction, use same quadrat method again, cut out second side.Make the cutting face of fringe bar base portion form typical wedge shape.The both sides of wedge shape bevel, Yi Bian long, thick slightly slightly, another side is short, thin slightly slightly.The length on long limit is not less than 1.5 centimetres, and the gap on length both sides is not more than 5 millimeters.

The fringe bar that is whittled into will keep bevel bright and clean, moistening.Preferably can be used for grafting immediately.When needing to place, preferably be kept in the clean container with moistening effect, also can the short time be dipped in clear water.

3, stock cutting

Select smooth position to block stock, with scraper section is cut smoothly,, the marginal portion that links to each other with cortex is scabbled if the stock otch is thicker.Then, select the position of stock annual ring broad, from bottom to top cut earlier a little angle (the 2-5 millimeters long gets final product), the down straight partial application from center, little angle lower end, about 1.5 centimetres of length, and choose out a side cortex.

4, plugged ear colligation

The scion bevel that then will cut inserts in the cortex of choosing out on the stock.It is outer that scion keeps thicker one side, position, one side thin prop up the thicker side of scion with finger inwardly, from top to bottom inserts slowly, and the bevel for the treatment of scion only stops during the arc incision of remaining the top, again with the about 1 centimetre toughened plastic band colligation of width.Note plastic tape the colligation direction will to open the direction of cortex opposite with peach, with guarantee colligation closely, and seal the otch of stock with bandage.

5, preserve moisture

After the grafting, must fully preserve moisture.

The decision of root a tree name actual conditions is wanted in the measure of preserving moisture.Ground grafting in garden can adopt heap to enclose wet soil or wood chip, and the 3-5 that only exposes terminal bud opens the way of blade and preserves moisture, and liftoff high-rise grafting can adopt the way of bag wet soil or moistening wood chip to preserve moisture, and can adopt also that plastic sack or plastic sheet are totally-enclosed preserves moisture.

6, shade

After preserving moisture, also to suitably shade, particularly adopt when plastic sack or plastic sheet are totally-enclosed preserves moisture, more need to shade.Shading of garden ground grafting can solve by covering shading screen.The plant grafting of the scattered distribution in mountain region can adopt ways such as covering indocalamus shell or hard ground paper to realize shading.

Two, the original place of wild Chinese torreya or strange land plantation grafting

1, the fringe bar is selected

The fringe bar that wild Chinese torreya grafting is required, the same with conventional grafting, also must select for use the base portion rugosity at the healthy and strong branch more than 2.5 millimeters.If can have more than 3 millimeters, then even more ideal.

2, scion cutting

Adopt draw cut method cutting scion, after scion wedge shape bevel was whittled into, the length on long limit preferably remained on more than 3 centimetres.

3, stock cutting

Must cut smooth around the disconnected anvil face.According to the rugosity of stock fracture, select 2-4 position, cut angle.The angle depth controlled is between 0.5-1.0 centimetre.The straight partial application downwards of little angle center, the degree of depth has just reached xylem, and about 2 centimetres of length, and choose out cortex when choosing out cortex, notice that several otch all will open cortex to same direction peach, so that colligation guarantees that each point can both reach the purpose of tight colligation.

4, colligation is preserved moisture, and shades

With conventional grafting.

5, the lime light of strange land grafting

Implement the strange land grafting, the lifting time is suitable, and preferably early March to early April carries out.Surgery whole branches and leaves of plant before the lifting earlier; keep 60-80 centimetre of high or needed trunk height; note protecting key root system during lifting; the long length that keeps of root is not less than 20 centimetres, does not allow and excessively hinders skin, notes behind the lifting preserving moisture; transport to the plantation point early; after the plantation, trunk is wrapped up with straw rope, preserves moisture and gives and shading at the grafting of position, top, bagging.

According to test, adopt above measure, can make the transplanting survival rate of wild Chinese torreya seedlings and graft survival rate all surpass 90%.
