Propagation and cultivation of Robinia pseudoacacia

The propagation of Robinia pseudoacacia is mostly grafted with Robinia pseudoacacia as rootstock, and grafting is generally carried out before germination in spring, and cutting is often used. The rootstock should be Robinia pseudoacacia with DBH greater than 6 cm, which has been transplanted many times. The trunk of rootstock is straight, strong and free from pests and diseases. Scions can be selected from plants with strong growth and no pests and diseases. Generally, 2-year-old branches with high lignification degree are selected as scions, and the length of scions is generally 8- 10 cm.

2. Grafting method

When grafting, the scion should be cut into wedges and inserted, and the cortex of the scion and the rootstock should be properly aligned, and then wrapped tightly with plastic tape to prevent loosening. The grafting place should be sealed with wax, and then covered with plastic bags to keep moisture. The wound can heal in about 20 days, and the scion will sprout by pulling the rope.
