Grafting method used for grafting, rootstock and scion should grow robust, moderate tenderness, no white pith, and the rootstock diameter of 3 to 4 mm, slightly larger than the scion. With picking and picking, do not scoop too much at one time so as not to affect the survival of the water loss.
Pick a 5-7 cm long seedling as the scion. Remove the lower larger leaves and leave two or three leaves at the top. The scion is cut into 15 cm long wedges with a double-sided blade, and then the rootstock is cut from the grafting site and cut open from the middle of the rootstock with a knife, which is slightly longer or equal in length (1.5 to 2 cm) than the cutting surface. Insert the scion into the fistula, align the two to form a layer, tightly seal the interface from top to bottom with a plastic strip, apply moisturizing on the cross-section of the rootstock, and put on a plastic bag to tie it. When bagging, the scion should be put into the bag along with a few pieces of wormwood leaves under the interface. If there are few or small wormwood leaves under the interface, a few pieces of wormwood leaves should be taken from other places, soaked in water and then put into the bag. Be careful when handling to prevent scuffing. The entire grafting process should be quick.
Immediately after grafting, shading measures were taken. Small areas were soaked in newspapers or kraft paper and all the grafted parts were covered with bamboo scaffolds. One or two days should start when the newspaper or kraft paper dry, spray water, the paper can be wet. Large area of ​​available shade nets to shade.
Two or three days later, open the plastic bag to a small mouth for ventilation, and observe that if the scion does not lose water and wilt, you can remove the sunshade in six or seven days. Scion basically survived after removing the sunshade, sunny days should pay attention to spray, spray three or four times a day, while increasing the bag vents, when the weather is particularly dry and hot, a small amount of spray to the bag, so that the scion gradually adapt to the outside environment. If it is found that the scion in the bag is dead, it should be patched in time. About 20 days after the scion begins to grow rapidly, the plastic strip on the scion should be removed in time.
