example 1

[0025] First weigh 60g of carboxymethyl cellulose and add it into a three-necked flask with a capacity of 1L, then add 300mL of ethanol solution with a mass fraction of 60% and 15g of aminoguanidine sulfate into the three-necked flask, stir and mix for 3min, then move the three-necked flask into the digital display In a speed-measuring and constant-temperature magnetic stirrer, stir the reaction for 2 hours at a temperature of 95°C and a rotation speed of 250r / min. After the reaction is completed, the product is spray-dried to obtain a dry product, and then weigh 200g of fly ash and 300g of alumina in sequence. Add 60g of polyvinyl alcohol into the ball mill, and pass through a 80-mesh sieve to obtain the sieved product. Take 30g of the sieved product and 50g of the dried product and mix for 10 minutes to obtain the mixture. Then select the discarded wood from the waste and old construction waste and wash it with water. 3 times, cut the cleaned wood into wooden boards with a si...

[0027]First, weigh 70g of carboxymethyl cellulose and add it to a three-necked flask with a capacity of 1L, then add 350mL of ethanol solution with a mass fraction of 60% and 18g of aminoguanidine sulfate into the three-necked flask, stir and mix for 4min, then move the three-necked flask into the digital display In a speed-measuring and constant-temperature magnetic stirrer, stir the reaction for 2 hours at a temperature of 98°C and a rotation speed of 275r / min. After the reaction is completed, the product is spray-dried to obtain a dry product, and then 250g of fly ash and 350g of alumina are weighed in sequence. Add 70g of polyvinyl alcohol into the ball mill, and pass through a 90-mesh sieve to obtain the sieved product. Take 35g of the sieved product and 55g of the dried product and mix for 13 minutes to obtain the mixture. Then select the discarded wood from the waste construction waste and wash it with water. 4 times, cut the cleaned wood into wooden boards with a size o...

[0029] First weigh 80g of carboxymethyl cellulose and add it to a three-necked flask with a capacity of 1L, then add 400mL of ethanol solution with a mass fraction of 60% and 20g of aminoguanidine sulfate into the three-necked flask, stir and mix for 5min, and then transfer the three-necked flask to the digital display. In a speed-measuring and constant-temperature magnetic stirrer, stir and react for 3 hours at a temperature of 100°C and a rotating speed of 300r / min. After the reaction is completed, the product is spray-dried to obtain a dry product, and then weigh 300g of fly ash and 400g of alumina in sequence. Add 80g of polyvinyl alcohol into the ball mill, and pass through a 100-mesh sieve to obtain the sieved product. Take 40g of the sieved product and 60g of the dried product and mix for 15 minutes to obtain the mixture. Then select the discarded wood from the waste construction waste and wash it with water. 5 times, cut the cleaned wood into wooden boards with a size o...

Abstract

The invention relates to a treatment method for dry and desert soil and belongs to the technical field of desertification treatment. According to the invention, after composting, slightly rotten wood and straws are taken as nutrient sources and used to provide nutrients to plants; then, populus euphratica is planted on edges and taken as a wind-proof and sand-blocking belt; sea-buckthorn is planted as a sand stabilization belt; during plantation, plantation pits are filled with the compost which provides the nutrients for growth of plants, and growth space is provided for the plants after complete degrading of the compost; after the plantation, a self-made sand solidification agent is paved to the sand surface; carboxymethyl cellulose and aminoguanidinium sulphate are grafted, so more hydrophilic groups are introduced, and water retention capacity is enhanced; the cellulose has high viscosity, so originally loose sand particles can be glued into large stable bodies and sand stabilization could be achieved; and then, water irrigation is conducted. According to the invention, the desert soil can be treated effectively; and the change rate of the moisture content in the soil is 5-8% within two to three months.

Description

technical field [0001] The invention relates to a treatment method for arid and desertified soil, belonging to the technical field of desertification control. Background technique [0002] Desertification has become an extremely important environmental and socio-economic problem in today's world, threatening the survival and development of human beings. Desertification is mainly caused by the interaction between unreasonable human activities and fragile ecological environment, which is manifested as the decline of land productivity, loss of land resources, and land degradation similar to desert landscape on the surface. [0003] The existing method of controlling desertified land mainly adopts afforestation, but this method requires large investment, slow effect, and long cycle, and cannot directly prevent soil moisture from evaporating and losing, and has little effect. In some areas, spray film, liquid film, etc. are used for treatment methods, but they can only play a ro...
