Low grafting

Shousing collection
in the fine varieties of female trees, choose to grow strong, leafy green, full bud eyes, no pests and diseases, the upper part of the canopy periphery of 1 year of raw branches for the spike. About 10 days before harvesting, remove the young part or flower spike on the top end of the maternal spike branch to promote full buds.
The spike is best to follow the pick, the spike should be dried after the dew on a sunny day, the picked spike should immediately cut off the leaves and the end of the young part, leaving only short leaf handle bud protection, cut immediately wrapped in plastic film, and hung a label, indicating the variety, date and place, the spike with plastic film wrapped in indoor shade. Daily defilm breathable for about half an hour, can be stored for 6 days. If the storage period is more than 6 days, it can be layered with moist river sand storage, covered with straw. Keep warm and cold, every 3 days to check the dry humidity of the spike and river sand. Collecting from the field requires long-distance transportation, the application of carton packaging, the wall should be covered with moss moisturizing.the grafting period
usually from December to March of the following year, with January to February before the ongring of spring as the best period for the change.grafting method cut
cutting method is easy to operate, high survival rate, germination pumping fast, the amount of spike, is the best grafting replacement method.saw (shearing)
in the replacement tree to choose a uniform distribution, oblique 1 to 2 branches 2 to 3, from the branch 15 to 20 cm sawing, shear should be smooth, slightly tilted, not tearing. The saw section skin layer is smoothed with a grafting knife, slightly tilted, and does not tear. Saw sectional cortical layer with grafting knife cutting smooth, leaving grafting section below the branch angle of large oblique side branches 1 to 2 as "pumping branches", the rest of the branches from the main branch sawing off, grafting site from the ground height of about 1 meter.
in the tree selection distribution is evenly distributed, oblique 1 to 2 branches 2 to 3, from the branch 15 to 20 cm sawn off, shears should be smooth, slightly tilted, not tearing. The saw section skin layer is smoothed with a grafting knife, slightly tilted, and does not tear. Saw sectional cortical layer with grafting knife cutting smooth, leaving grafting section below the branch angle of large oblique side branches 1 to 2 as "pumping branches", the rest of the branches from the main branch sawing off, grafting site from the ground height of about 1 meter. Select the smooth bark, at the junction of the cortical layer and the wood part, slightly tilted to the wood part 5 to 10 degrees, slightly with the wood part of a knife, 2 to 2.5 cm deep, straight cut, the joint diameter thick more than 6 cm, cut two incisions in the opposite face of the section, graft two joints, easy to heal the joint section as soon as possible.Seching Spike
Left-handed grip spike, right-handed grip knife, slightly with a woody part of the base of the spike cutting 2 to 2.5 cm long cutting surface, relative to one side cut into 45 degrees slope, length 1 to 1.5 cm short cutting surface, The two knives intersect into a line, inverted spike, leaving 1 to 2 bud eyes cut, the spike cut into wedges, 3 to 4 cm long, with 1 to 2 full bud eyes, bud eyes should be between the two cutting surfaces, long, short two cutting surfaces to be straight.the formation layer of the
-spike, encased, and birch must be aligned and closely close, and the depth of the spike must be appropriate for micro-dew cutting surface, so as to heal the wound with the birch section. Immediately after the spike with a thin film band band, first in the upper part of the joint two circles, fixed the spike, so that the spike and birch inlet form a layer of dense, and then cover the birch section with a film, continue to tie the film belt, wrap the entire grafting part, the spike part of the film left bud eye wrap.-embedded
is suitable for trunk high, grafting site dry diameter of more than 15 cm thick intersorbed trees, embedding operation is more difficult, survival rate is lower than cutting, spike requirements are thick and the amount is large.sawing
is generally 40 to 50 cm off the ground sawing, the trunk should be left 1/4 inverted, avoid sawing off. If the canopy is large, the canopy should be sawed before the canopy part of the large branches, reduce the weight of the canopy, prevent the trunk tearing, broken.Birch saw slot
hand saw in the smooth section on one side of the saw width of about 1 cm, depth 1.2-1.5 cm, length 5 to 6 cm wedge gap, with grafting knife to repair the saw groove, so that the groove is slightly wider than the outside of the groove, the groove is slightly wider than the bottom of the groove, the bottom 2 cm of the groove is tilted from the inside out, the bottom of the groove to be straight. Open a slot on the opposite side of the corresponding.Swiping spike
on both sides of the spike branch symmetrically, slightly with the wood part cutting growth of 4 to 5 cm slope, to the lower end of the inner side cutting length of about 2 cm short slope, deep to the woody myelin of the spike, a wedge, its shape is similar to the size of the interface, the spike cut into, aligned with the two sides to form a layer insertion interface, slightly tap down, so that the spike close.the
interface gap is blocked with sawdust, the joint is tied firmly with a film belt, the section is covered with the film and tied tightly, and the spike part of the film is covered with buds and eyes.
