First of all, we need to know that the time for picking up the larvae is usually between December in December and March in the coming year. The best period is from January to February before spring shoot sprouting.
Second, we need to choose high-quality scion, and what kind of scion is good?
Select one-year-old shoots in the middle and upper part of the circumference of the crown, and require strong growth, dark green leaves, full shoots, and no pests and diseases. About 10 days before harvesting, the young shoots or spikes at the upper ends of the shoots are removed to promote the fullness of the shoots.
After the dew-drying is done, the cuttings are sunny and the treatment immediately before grafting is changed to ensure the survival rate of grafting.
The scion shall be cut immediately and the young part of the end shall be cut off immediately, leaving only the short petiole to protect the bud. Immediately after cutting, wrap it with plastic film and hang a label to indicate the variety, date and place. The scion shall be wrapped in a plastic film. Indoor shade. Membrane breathe about half an hour every day, can be stored for 6 days. If the storage period exceeds 6 days, moist river sand can be used for layered storage and covered with straw. Insulate and protect against cold, and turn it every 3 days to check the dryness of the scion and river sand. To collect long-distance transportation from outside the field, use carton packaging, and moss and moisture should be laid around the wall.
Again, here's an easy-to-use, high survival rate method for cutting-edge connections—cutting methods. This method germinates shoots quickly, and saves the amount of scion, which is the best method for grafting and grafting.
1, saw (cut) anvil
In the alternate tree, select evenly distributed, slanting 1~2 branches 2~3, sawing off 15~20 cm from the branches, the cut should be smooth, slightly inclined, not torn. The keratotomial section of the cortex was smoothed with a grafting knife, and 1 to 2 oblique branching branches with a large branching angle under the grafting part were used as a “pumping branchâ€, and the remaining branches were sawn from the main branching branch. The height of the grafting site was approximately 1 from the ground. Meters around.
2, anvil
Select the bark smooth place, at the junction of the cortex and xylem, slightly inclined to the xylem 5 to 10 degrees, slightly with a xylem longitudinally cut a knife, depth 2 to 2.5 cm, incision straight, joint diameter more than 6 cm thick, in the section Two incisions are cut relative to one another and two scions are grafted to facilitate the healing of the cross section.
3, scion
Hold the scion in the left hand, hold the knife in the right hand, and cut a long 2 to 2.5 cm long noodles in the base of the scion with a slight depth of 2 to 2.5 cm. Cut a 45-degree slant and a short cut of 1 to 1.5 cm in length at the base of the scion. Inverted spikes, leaving 1 ~ 2 buds cut off, scion cut wedge-shaped, 3 to 4 cm long, with 1 to 2 full bud eyes, buds should be between the two noodles, long and short two noodles to be straight.
4, cuttings, dressing
The formation layer of scion and rootstock must be aligned and closely cling to each other. The depth of cutting is suitable for micro-cut surface, so as to facilitate the healing of wounds with root stocks. Immediately after the cuttings, bandages are used to wrap them in a thin film band. Twist two times in the upper part of the joint to fix the scion so that the scion and the rootstock cut form a layer. After that, the rootstock section is covered with a film, and the film band is continued to be wrapped around the entire grafting area. , The scion part is wrapped with mulching eyes.
