The tool (1) is used as a blade, and the beard must be peeled off with a double-sided thin blade. This type of blade is also convenient and inexpensive to use.
(2) Bamboo top insert (bamboo stick). Choose bamboo bamboo sticks that are of better quality and you can prepare both bamboo sticks and bamboo sticks.
(3) A small lunch box is used to contain scion seedlings. The panicle seedlings can be directly transferred to the pan to take scion.
When the rootstock is grafted and plugged, the scion watermelon is sowed. The scion cotyledon just spread out into the cotyledon flattening for the appropriate grafting period. When grafting, the true leaves and growth points of the rootstock are first trimmed with a blade, and a bamboo stick is used to form a 45-60 degree angle from the right side of the cotyledon veins and the cotyledon to the inner skin of the left subcotyle to incline along the epidermis of the embryonic stem. Penetrate the outer epidermis of the lower part of the left cotyledon, whichever is the depth. Another blade was cut into a bevel about 1 cm below the watermelon cotyledon, and the scion was inserted into the hole of the rootstock. When the insert was inserted, the scion sloped downward, and the scion cotyledon and the rootstock cotyledons were cross-shaped.
Take a strong rootstock seedling and use a blade to cut off the first true leaf and growing point from the base. Scratch the growth point of the buds between the leaves and leaves of the cotyledon to eliminate the possibility of the roots sprouting again. Using a jack plug (bamboo stick) at the cut at the top of the rootstock, the direction of the connecting line of the cotyledons descends obliquely into the lower axis of the rootstock cotyledon, forming a hole about 0.5-1 cm deep and reaching the cortex of the hypocotyl. In other words, the eyes of the bamboo stick can be seen through the skin of the embryonic axis of the rootstock. Cut the wedges into two beveled wedges. The bevels should be cut in one piece. The surface should be smooth and free from dirt impurities. Carefully insert the sharpened scion into the top hole and insert it tightly into the skin, tightly integrated with the rootstock, but not with the scion.
The connection method requires that the hypocotyls of the rootstock and scion are highly suitable. It is common to sow the watermelon scion first and then sow the rootstock. The time is about 6 to 7 days. Remove the growing point of the rootstock and cut a cut of nearly 30 degrees in the 1 cm under the cotyledon, 0.5 to 0.7 cm long. The direction of the cutting of the scion is opposite to the direction of the cutting of the rootstock. The length of the cutting is the same as the length of the rootstock, and then the two cuts are made. Consistently, clip it with a graft clip or wrap it with plastic tape. The two grafts were planted in the nutrient bowl at the same time. After 7 to 10 days the interface was fully integrated, the scion was cut off under the interface. One day before cutting, it is best to pinch the stem of the scion by hand, destroying the vascular bundle, so that the seedling will not grow after the root cut.
According to Pan Qingshan's introduction, Changle watermelon planting area basically uses plugging method, because the method is simple, no graft clips, grafting speed, is a good way to save effort and labor; and the grafting survival rate is relatively high In Changle, the planting area per household is basically no less than 3 mu, so the plugging method has been applied for a large area for many years.
