The present invention discloses a flower preservation tube, which comprises a main body, and the main body is configured with a water storage portion and an insertion portion, and further with a water reservoir communicated with the water storage portion and the insertion portion. The water storage portion is configured with a soft section and a hard section. The insertion portion is configured with an insertion hole and a soft and deformable surrounding wall. An inner joining angle is formed between the surrounding wall and the hard section within the water reservoir and is greater than 95 degrees. Thus, while inserting flower into the insertion hole, the surrounding wall is forced to be deformed and recessed along the flower insertion direction, so as to keep the insertion hole and the flower in a sealed state. Therefore, when the flower absorbs the water in the water reservoir, the water in the water reservoir is decreased to force the soft section deformed, so as to squeeze and pump the water to be absorbed by the flower.本發明主要揭示一種花卉保鮮管,其包括:一主體,該主體設有一貯水部及一插置部,且主體內設有一連通貯水部及插置部之蓄水室,該貯水部設有一軟質段及一硬質段,而插置部設有一插孔及一軟質可變形之圍壁,該圍壁與硬質段之間於蓄水室內形成一內銜接角,該內銜接角之角度大於95度;藉此,將花卉插入插孔,可迫使圍壁沿花卉插設方向變形內凹,以保持插孔與花卉為密接狀態,因此,花卉吸收蓄水室內的水份時,蓄水室內之水份減少逼迫軟質段變形,並擠壓推引水份以供花卉吸收。1‧‧‧主體11‧‧‧貯水部12‧‧‧插置部121‧‧‧插孔122‧‧‧圍壁
