In order to solve the problems of watermelon cultivars, effectively prevent the occurrence of the wilt disease, enhance the resistance to grafting and the capacity of absorbing fertilizer, and effectively improve the yield, quality and benefit of watermelon. The use of grafting technology to turn good seedlings off is the key to capturing the high yield, quality and efficiency of seedless watermelons. The sowing technique measures are as follows First, soaking seed germination Seeds of rootstock are kept in warm water of 55°C-60°C for 15-20 minutes, then the water temperature is maintained at 25°C-30°C, soaking for 18-24 hours, removing the artificial broken shell, at 30°C-33°C Germination. Watermelon seeds can be soaked in the same way for 5 to 7 days after the rootstock seeds are sowed. Second, sowing when the germination seeds more than 70% break the mouth can be sown, planted before planting foot water, take one-third of the Wufu Mixture soil spread evenly in the seedbed, the rootstock seeds broadcast in the nutrition body, generally each body 1 to 2 tablets, and then the remaining two-thirds of the drug soil cover the seeds. Watermelon seeds that have been promoted by buds can be sown 7 to 10 days after the rootstock seeds are sown or when the rootstock seeds are unearthed. After pouring enough water, the seeds can be spread evenly, so that 1000 to 1500 seeds can be sown and then the soil can be covered. General watermelon seedlings begin to graft about 5 days after emergence. Third, the grafting method is mostly used for the top plugging method. The cotyledon of watermelon is in the shape of “丫†and the flattening period is the suitable period for grafting. During grafting, the true roots and growth points of the rootstocks are first trimmed with a blade (can be removed 2-3 days before grafting to promote thickening of the hypocotyls, which is conducive to improving the survival rate and convenience of grafting), and then the bamboo shoots are connected with the cotyledons. Insert the embryonic axis of the rootstock obliquely in a direction of about 0.5 to 1 in. (Note: The tip of the bamboo stick reaches the cortex of the other side of the hypocotyl of the cotyledon, and it is advisable to touch the tip of the finger in this area). Remove the scion, use a blade to cut 1 to 1.5 inches below the cotyledon to make it "10" shape, then quickly pull out the bamboo stick in the rootstock, and accurately insert the scion into the direction of the bamboo stick and insert it obliquely into the hole of the rootstock. After cocooning, the cotyledons of the scions intersect with the cotyledons of the rootstock in a "ten" shape.
