Example Embodiment
[0017] Example 1
[0018] Weigh 1 part of polyvinyl alcohol, 5 parts of polyacrylic acid water retaining agent and 5 parts of urea to dissolve in water. Mix 15 parts of attapulgite soil, 15 parts of straw crushed material, 59 parts of fine sand (parts refer to parts by weight, as in Examples 2 and 3) and an appropriate amount of plant seeds. After fully mixing in a mixer, add the dissolved The solution, continue to stir for 30 minutes, and then discharge for use.
[0019] Spread the prepared material evenly on the sand dunes of the desert road in a thickness of about 10 cm, and cover it with a mulch film. After 15 days, remove the mulch and the plants can grow normally.
Example Embodiment
[0020] Example 2
[0021] Weigh 1 part of polyvinyl alcohol and 1 part of starch, 7 parts of polyacrylic acid water retaining agent, 5 parts of urea, and 2 parts of potassium dihydrogen phosphate and dissolve in water. After mixing 20 parts of attapulgite soil, 20 parts of straw crushed material, 44 parts of fine sand soil, and appropriate amount of plant seeds in a mixer, add the dissolved solution and continue mixing for 30 minutes before discharging for use.
[0022] Spread the prepared material evenly on the sand dunes of the desert road in a thickness of about 10 cm, and cover it with a mulch film. After 15 days, remove the mulch and the plants can grow normally.
Example Embodiment
[0023] Example 3
[0024] Weigh 1 part of polyacrylamide, 1 part of water glass, 10 parts of polyacrylamide water-retaining agent, 2 parts of humic acid, and 1 part of potassium dihydrogen phosphate and dissolve in water. After 30 parts of attapulgite soil, 25 parts of wheat straw crushed material, 30 parts of fine sand soil and appropriate amount of plant seeds are fully stirred in a mixer, add the dissolved solution and continue to stir for 30 minutes before discharging for use.
[0025] Spread the prepared material evenly on the dunes of the deserted grassland into a thick layer of about 10 cm. The plants germinated and grew normally after 10 days.
