Abstract: A method for cultivating a Tung tree seedling through hypocotyle grafting includes selection of a sand storage time of a rootstock (Vernicia montana Lour.) seed, seedbed construction, scion collection, scion cutting, rootstock cutting, bandaging, transplantation and management, and the like. A grafted plant obtained by a traditional grafting method (bud grafting) for Tung tree is easy to break at a grafting interface; and when the stem grafting is conducted, because a scion is thick, a rootstock for grafting must be cultivated one year in advance. These grafting methods have production problems such as long cycle and high cost, which can be solved by the present disclosure. The present disclosure has a short rootstock cultivation time, simple grafting operations, a high grafting efficiency, and a high survival rate, greatly shortens a cycle of asexual propagation-based seedling cultivation for Tung tree.
