Example Embodiment
[0007] Example 1:
[0008] 1) Components and proportions (in parts by weight):
[0009] Grassland peat (12% water content) 4
[0010] Straw fiber (bean stalk fiber, length 3mm) 2.5
[0011] Clay minerals (expanded vermiculite) 1.2
[0012] Polyacrylamide (molecular weight 10 million, charge density 30% 0.3
[0013] Dispersant (polyvinyl alcohol) 0.1
[0014] P buffer (mixed phosphate) 0.03
[0015] 2) Application results:
[0016] Used for the greening of the side slope of Chongqing Shangjie Expressway, with a slope of 10 degrees and an area of 5000m 2 , Poor erosion resistance. After mixing the present invention with limestone soil evenly, it is sprayed on the surface of the slope by mechanical spraying, the dosage is 5kg / m 2 , And water to moisten. The application results not only improved the stability of the rock and soil itself, but also enhanced the erosion resistance of the rock and soil. It was determined one month later that the bulk density of the rock and soil decreas...

[0017] Example 2:
[0018] 1) Components and proportions (in parts by weight):
[0019] Grassland peat (water content 10%) 6
[0020] Straw fiber (rice straw fiber, length 2.5mm) 1.8
[0021] Clay minerals (expanded vermiculite) 2.0
[0022] Polyacrylamide (molecular weight 8 million, charge density 20%) 0.4
[0023] Dispersant (polyvinyl alcohol) 0.5
[0024] PH buffer (mixed phosphate) 0.02
[0025] 2) Experiment and results:
[0026] The sandstone slopes in Dushan County, Guizhou Province, covering an area of 50 mu, have thin soil, poor fertility, low annual rainfall, and harsh soil and climatic conditions, resulting in poor quality and low yields of food crops. Use manual paving, buried under 5mm soil layer, dosage is 1kg / m 2 . After 45 days of application, it was determined that the bulk density of the rock and soil decreased by 25%, the effective water holding rate of the rock and soil increased by 12%, the porosity increased by 20%, the water-stable aggregate content incr...

[0027] Example 3:
[0028] 1) Components and proportions (in parts by weight):
[0029] Grassland peat (moisture content 8%) 8
[0030] Straw fiber (wheat straw fiber, length 2.5mm) 1
[0031] Clay minerals (expanded perlite) 0.5
[0032] Polyacrylamide (molecular weight 8 million, charge density 30%) 0.6
[0033] Dispersant (polyvinyl alcohol) 0.3
[0034] PH buffer (mixed phosphate) 0.05
[0035] 2) Experiment and results:
[0036] The shale slope of Xichang Jinping Power Station, with an area of 1000m 2 , The corrosion resistance is poor, after mixing the present invention with shale rock and soil evenly, it is sprayed on the surface of the slope by mechanical spraying, the dosage is 0.5kg / m 2 . After 45 applications, it was determined that the rock and soil volume decreased by 27%, the effective rock and soil water holding rate increased by 10%, the porosity increased by 25%, the water-stable aggregate content increased by 35%, and the permeability increased by 32%.
