Can Watermelons Be Grafted?
A comprehensive introduction to whether watermelons can be grafted in the field of green plants and flowers, the following is introduced by the editor of this site.
Can Watermelons Be Grafted?
Watermelons can be grafted, often done in spring. The methods used for grafting include top-cut grafting and adjacent grafting. The rootstock commonly used for watermelon grafting is pumpkin and gourd, which have strong affinity and high survival rates, and do not adversely affect the quality of the watermelon. After grafting, it is necessary to maintain the temperature in the greenhouse at 25-30 degrees Celsius during the day and 18-20 degrees Celsius at night to help improve the survival rate of the plants.
Is Watermelon Grafting Possible?
Watermelons can be grafted, and the grafting time is often in spring. Both top-cut grafting and adjacent grafting are suitable to be carried out in the warm spring.
Watermelon Grafting Method
Watermelon grafting rootstock
Watermelon grafting commonly uses pumpkin and gourd as rootstock, which have strong affinity and high survival rates, and do not adversely affect the quality of the watermelon. Pumpkin rootstock is the most resistant to wilt, has strong growth momentum, and can promote early maturity of watermelons, increasing their yield.
Watermelon Grafting Steps and Method
1. Pumpkin and Watermelon Grafting:
When the pumpkin seedlings' cotyledons are fully expanded, remove the growth point, make a 45-degree diagonal cut under the cotyledon with a blade, and at the corresponding part of the watermelon scion, make a 45-degree diagonal cut upwards. Insert the scion cut into the rootstock stem cut, secure the joint with a grafting clip, and after 7 days, the joint heals and the scion root is cut off, and after 15 days, the grafting clip is removed.
2. Top-cut Grafting with Gourd as Rootstock:
When grafting watermelon with gourd, leave two leaves of the gourd rootstock, use a bamboo stick of the same thickness as the watermelon seedling, insert it diagonally along the leaf veins of the gourd leaf and at a 45-degree angle to the gourd stem, make a diagonal cut under the cotyledon of the watermelon seedling with a blade, and insert the watermelon scion cut into the rootstock after removing the bamboo stick.
Watermelon Post-Grafting Management
About 20-40 days after grafting, it can be observed whether the watermelon has survived. Maintaining the temperature in the greenhouse at 25-30 degrees Celsius during the day and 18-20 degrees Celsius at night is beneficial for the survival of the grafting joint and should not be exposed to strong sunlight.
The above is the specific content of whether watermelons can be grafted, for everyone's reference and operation.
