PROBLEM TO BE SOLVED: To provide a bamboo tube liquid encapsulation method and a bamboo tube liquid encapsulation device which encapsulate a liquid in a hollow part of a bamboo tube without forming an injection path in the bamboo tube.SOLUTION: When encapsulating a liquid in a bamboo tube (4) having a hollow part (3) formed between joints (2) of a bamboo (1), after the pressure in the hollow part (3) of the bamboo tube (4) is reduced, an end part of the bamboo tube (4) is immersed in a liquid having a higher pressure than the pressure in the hollow part (3) of the bamboo tube (4), and thereby the liquid is encapsulated in the hollow part (3) of the bamboo (4). Further, before the pressure in the hollow part (3) of the bamboo tube (4) is reduced, the bamboo tube (4) is heated. Furthermore, after the liquid is encapsulated in the hollow part (3) of the bamboo tube (4), both end faces of the bamboo tube (4) are sealed. |
