Embodiment 1
[0052] Example 1: Experiments on wind erosion and fertility of 0.3 mu of experimental sandy land in Ordos, Inner Mongolia.
[0053] Bacteria-rich domestic sludge (taken from the Wushen Banner Sewage Treatment Plant in Ordos) and biogas residue (produced in rural areas), stale straw rich in actinomycetes and fungi (produced in pastoral areas), organic flocculant polyacrylamide After drying at room temperature, the mixture is formed and stored. The weight ratio of each component is 15:15:1.
[0054] Take 100 parts of local chestnut soil, 10 parts of highly weathered weathered coal, 10 parts of the above mixture, stir well with appropriate amount of water, and add 0.1 part of crosslinking agent borate ion to carry out cross-linking at room temperature to convert into water swellable but The super absorbent flocculent mixture that will not disperse will be broken into clusters of microorganisms / microbial culture medium after being slightly dried. The appearance characteristics of the ...
Embodiment 2
[0059] Example 2: The experimental beach in Quanzhou, Fujian Province, which is 2 meters wide and 10 meters long, can be submerged when the tide reaches the highest tide. Water erosion test.
[0060] The domestic sludge rich in bacteria (a sewage treatment plant in Quanzhou), the decayed leaves (broken into powder) in the forest area rich in actinomycetes and fungi, and cationic modified starch with organic flocculant are dried at room temperature to form a mixture, and stored. The weight ratio of each component is 20:6:5.
[0061] Take 100 parts of local red clay, 10 parts of highly weathered weathered coal, 25 parts of the above mixture, stir well with proper amount of water, and add 0.3 parts of crosslinking agent borate ion to crosslink at room temperature. It will be converted into water swellable but not The dispersed superabsorbent flocculent mixture is slightly dried and broken into clusters of microorganisms / microbial culture medium. The appearance characteristics of the ...
