Embodiment 1
[0022] The preparation method of the degradable bamboo fiber straw of the present embodiment, the method is:
[0023] S1. Bamboo scrap fiber pretreatment: Bamboo scrap is first screened, bamboo fiber with a length less than 10mm is selected, mixed with water at a mass ratio of 1:1, steam blasted, rinsed with water, and heated at a temperature of 50°C After drying for 10 hours under the condition of 10 h, the pretreated bamboo fiber with a water content of ≤ 10% was obtained; the steam explosion treatment method is: after the temperature is 180 ° C and the steam pressure is 1.8 MPa, the pressure is maintained for 45 seconds, and the bamboo fiber is released instantly. After pressure to normal pressure, naturally cool to room temperature; The massfraction of hemicellulose in the described pretreated bamboo fiber is 20%, and the massfraction of lignin in the described pretreated bamboo fiber is 23%;

Embodiment 2
[0030] The preparation method of the degradable bamboo fiber straw of the present embodiment, the method is:
[0031] S1. Bamboo scrap fiber pretreatment: Bamboo scrap is first screened, bamboo fiber with a length less than 10mm is selected, mixed with water at a mass ratio of 1:2, steam blasted, rinsed with water, and heated at a temperature of 65°C. After drying under the condition of 7h, the pretreated bamboo fiber with water content≤10% is obtained; the method of steam explosion treatment is: after the temperature is 200°C and the steam pressure is 1.5MPa, the pressure is kept for 60s, and then the bamboo fiber is released instantly. After pressure is to normal pressure, naturally cool to room temperature; The massfraction of hemicellulose in the described pretreatment bamboo fiber is 15%, and the massfraction of lignin in the described pretreatment bamboo fiber is 25%;
