Embodiment 1
[0093] Polyvinyl alcohol is selected as the solid organic substance that can dissolve in water;
[0094] Stir polyvinyl alcohol and water according to the weight ratio of 5:100 to form a solution;
[0095] Get 1000kg of sandy soil, then take 200kg of solution formed by dissolving polyvinyl alcohol in water, add the solution and an appropriate amount of farmyard manure to the sandy soil and mix, then mix and stir evenly to form modified sandy soil; the polyvinyl alcohol in the modified sandy soil and the The weight ratio is 1:105.0;
[0096] Spread the modified sand outdoors with a thickness of about 10cm. The water in the modified sand is well preserved. Under the spring climate conditions in Chongqing, the evaporation is small. Take part of the modified sand and take measures such as drying to make the surface After dehydration, the surface of the modified sand is compacted into a whole; then water is sprinkled on the surface of the modified sand after dehydration, the subst...
Embodiment 2
[0100] The solid organic substance that can dissolve in water is selected from hydroxypropyl methylcellulose;
[0101] Stir hydroxypropyl methylcellulose and water according to the weight ratio of 0.2:100 to form a solution;
[0102] Get 1000kg of sandy soil, then get 190kg of hydroxypropyl methylcellulose solution, mix the sandy soil with the solution and 5kg of agricultural compound fertilizer and stir evenly to form modified sandy soil, and the material hydroxypropyl methylcellulose in the modified sandy soil and sandy soil The weight ratio is 1:2637;
[0103]Spread the modified sand outdoors with a thickness of about 10cm. The water in the modified sand is well preserved. Under the spring climate conditions in Chongqing, the evaporation is small. Bonded together, the sand is in a plastic wet state;
[0104] Spread the modified sandy soil containing grass seeds outdoors, and the water in the modified sandy soil is well preserved. Under spring climate conditions, after one...
Embodiment 3
[0107] The solid organic matter that can dissolve in water is selected carboxymethyl cellulose sodium for use;
[0108] Stir carboxymethylcellulose sodium and water according to the weight ratio of 1:100 to form a solution;
[0109] Get 1000kg sandy soil, get carboxymethyl cellulose sodium solution 210kg again, with sandy soil, carboxymethyl cellulose sodium solution, 1 kilogram of agricultural compound fertilizer and 2 kilograms of nitrogen, phosphorus and potassium mixed fertilizers, mix and stir, form modified sandy soil, The weight ratio of the substance sodium carboxymethyl cellulose in the modified sand to the sand is: 1:481.0;
[0110] Spread the modified sand outdoors with a thickness of about 10cm. The water in the modified sand is well preserved. Under the climate conditions of spring in Chongqing, the evaporation is small, and the appearance of the modified sand is similar to that of soil. Drying and other measures, after the surface loses water, the surface plate ...
