How to graft watermelon seedlings?

Tweezers can be used for grafting rootstocks, but if the scion type is triploid or tetraploid watermelons, it is best to use Satomon (F1). Grafting method can be used to connect and dock, watermelon scion seedlings to expand the cotyledon, the rootstock with the first true leaf appears suitable grafting period. The method of sowing is the same as that of cucumber; scion early sowing is 5~7 days, rootstocks are soaked in water of 20~30°C for 6~8 hours, then the rootstock is required to go to the true leaves and growth point, and then the blade is used between the two leaves, and the embryonic axis is one. Cut a 1-cm incision down the side, cut the wedge into a wedge, insert the incision, and clamp it with a graft clip. The management after grafting is basically the same as that of cucumber. The only difference is that the bed temperature during healing is 1~2°C higher than that of cucumber.
