How to improve the survival rate of grafted watermelon? Sharing practical measures

(Agricultural Wealth Network) First, select rootstocks with strong affinity for the watermelon scion variety, and strictly control the size of the rootstock and scion. Second, cultivate rootstock and scion seedlings with thick hypocotyls. Remove the growing point of the rootstock seedlings 2 days before grafting to improve the grafting survival rate. Third, be proficient in grafting techniques. First, make the contact surface between the rootstock and scion as wide as possible; second, make the rootstock and scion fit tightly together; when using the top insertion method, the scion must be inserted firmly; third, the movements during grafting must be quick and accurate to reduce the exposure time of the cut surfaces of the rootstock and scion to the air. Fourth, strengthen the seedbed management of grafted seedlings. Management must be done well in several aspects, including the temperature, humidity, and light of the seedbed, as well as removing rootstock sprouts and cutting the scion roots.
