[0019] Embodiments
[0020] A method of grafting of catalpa grafting, including the following steps:
[0021] S1. Select two-year-old ash with a diameter of 1.0 to 2.0 cm and a row spacing of 40 cm × 40 cm as the rootstock, and after the stubble of the ash rootstock is 15 to 20 cm from the ground, the cutting on the side of the wood cut surface is exposed to form a layer;
[0022] S2. Cut slightly xylem on the inside of the formation layer to form an inverted triangle with a depth of 2 to 3 cm;
[0023]S3, the diameter of 0.5 ~ 2.5cm, no disease and insect pests, healthy annual water catalpa branches, in the shade of 0 ° C ~ 5 ° C sand storage, sand mixed with about 5% of the solid hydrogel particles, preservation humidity of 45% ~ 75%, preservation process needs to observe the scion from time to time, to prevent the scion loss of water dry or moldy, etc.; the solid hydrogel particles are superabsorbent polymer resin fully absorbed water expansion into spherical particles; the sup...
