Embodiment 1
[0017] (1) Select healthy reed stalks without insect eyes, and classify reed stalks in different diameter ranges.
[0018] (2) To prepare a modifier, take 30% hydrogen peroxide and use deionized water to prepare solution A with a concentration of 1%, and place it in an inverted test tube for use.
[0019] (3) In step 2, the cut reed stalks with equivalent diameters are put into the test tube containing solution A, and the modifier should be submerged in the reed stalks. In order to prevent the reed stalks from floating on the liquid surface and causing uneven impregnation, seal the container mouth with plastic wrap to avoid the reed stalks from floating out of the test tube during heating and immersion. Put the test tube soaked in the reed stalks into a water bath, and soak at a constant temperature of 80-90°C for 1 hour. After the impregnation is complete, take out the reed stalks and put them in a ziplock bag, and keep them sealed.

Embodiment 2
[0022] (1) Select healthy reed stalks without insect eyes, and classify reed stalks in different diameter ranges.
[0023] (2)) To prepare a modifier, take 30% hydrogen peroxide and use deionized water to prepare solution B with a concentration of 2%, and place it in an inverted test tube for use.
[0024] (3) In step 2, the cut reed stalks with equivalent diameters are put into the test tube containing solution B, and the modifier should be submerged in the reed stalks. In order to prevent the reed stalks from floating on the liquid surface and causing uneven impregnation, seal the container mouth with plastic wrap to avoid the reed stalks from floating out of the test tube during heating and immersion. Put the test tube soaked in the reed stalks into a water bath, and soak at a constant temperature of 80-90°C for 2 hours. After the impregnation is complete, take out the reed stalks and put them in a ziplock bag, and keep them sealed.

Embodiment 3
[0027] (1) Select healthy reed stalks without insect eyes, and classify reed stalks in different diameter ranges.
[0028] (2)) To prepare a modifier, take 30% hydrogen peroxide and prepare a solution C with a concentration of 3% with deionized water, and place it in an inverted test tube for use.
[0029] (3) In step 2, the cut reed stalks with equivalent diameters are put into the test tube containing the solution C, and the modifier should be submerged in the reed stalks. In order to prevent the reed stalks from floating on the liquid surface and causing uneven impregnation, seal the container mouth with plastic wrap to avoid the reed stalks from floating out of the test tube during heating and immersion. Put the test tube soaked in the reed stalks into a water bath, and soak for 3 hours at a constant temperature of 80-90°C. After the impregnation is complete, take out the reed stalks and put them in a ziplock bag, and keep them sealed. It is measured that its density inc...
