The invention discloses a laser-modified round bamboo anisotropic processing method, which belongs to the field of round bamboo modification. A laser-modified round bamboo anisotropic processing method is to irradiate round bamboo with laser, and the round bamboo absorbs the laser energy and converts it into heat energy, and the lignin in the round bamboo interacts with cellulose, hemicellulose, etc. in three-dimensional space under the action of heat. With the combined effect, the material distribution in the round bamboo changed and the anisotropy decreased. A kind of processing method of laser modified round bamboo anisotropy of the present invention can not only effectively improve the anisotropy of round bamboo, improve the anti-split performance of round bamboo, at the same time, when round bamboo is molded, the round bamboo after modeling The laser treatment of the bent stress-bearing parts can reduce the internal stress of the round bamboo shape and improve the stability of the round bamboo shape. Thermal modification of round bamboo can greatly expand the application field of round bamboo.

The invention provides a chestnut tree grafting method, which relates to the technical field of fruit tree grafting. The grafting method of the present invention increases the growth space of the callus by leaving grooves on the rootstock, increases the healing area between the scion and the rootstock, and enables the callus to occupy the entire rootstock groove, thereby naturally forming a joint with the scion. The "T-shaped connection" has a strong ability to resist wind or other external forces, and enhances the branch's ability to resist splitting; and the existence of the rootstock groove can hinder but not block the water and nutrient supply of the rootstock, so the humidity in the "rootstock groove" is relatively high. High is not affected by the external temperature, helps the formation and growth of callus, and greatly improves the survival rate of grafting, which can reach 100%.
