Embodiment 1
[0016] In terms of parts by weight, dissolve 15 parts of gelatinized starch in 67 parts of water, then add 10 parts of water glass, 0.03 parts of sodium lauryl sulfate and 8 parts of formaldehyde, stir well and pour it into a tubular mold. Cured for 18 hours, soaked and dried.
Embodiment 2
[0018] In terms of parts by weight, dissolve 18 parts of carboxymethyl starch in 69 parts of water, then add 8 parts of water glass, 0.05 parts of OP-10 and 5 parts of glutaraldehyde, stir well and pour it into a tubular mold. Cured for 6 hours, soaked and dried.
[0019] The prepared material is cut into about 30-40cm in length, and buried in the tree pit parallel to the trees during afforestation, the lower end is close to the root of the tree, and the upper end just exposes the filled soil layer. In order to collect rainwater, the top of the tree pit can be covered with mulch, and a small hole is made near the upper end of the material.
Embodiment 3
[0021] In terms of parts by weight, dissolve 11 parts of phosphate starch in 77.9 parts of water, then add 9 parts of water glass, 0.1 part of glycerin and 2 parts of acetaldehyde, stir evenly, pour into a tubular mold, and cure at 65 ° C for 15 hours. Soak, dry.
