Abstract

The invention provides a water-retaining agent used for saline-alkali soil corn and containing fly ash. The water-retaining agent comprises starch, acyclic acid, acrylamide, fly ash, ulva lactuca powder, sargassum powder, eggplant straw powder and corn straw powder. The invention further provides application of the water-retaining agent to corn planting in saline-alkali soil. The water-retaining agent has the advantages that the prepared water-retaining agent has high water absorbing capability in tap water, rainwater, and NaCl solution with a concentration of 0.9%, the capability of water absorption in the tap water can reach 790-940 times the weight of itself, the capability of water absorption in the rainwater can reach 670-830 times the weight of itself, and the capability of water absorption in the NaCl solution with a concentration of 0.9% can reach 390-530 times the weight of itself.

Description

technical field [0001] The invention relates to a water-retaining agent for saline-alkali corn containing fly ash and a preparation method thereof, belonging to the technical field of water-retaining agents. Background technique [0002] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. The main oxide composition of fly ash in thermal power plants in my country is: SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2, etc. With the development of the power industry, the discharge of fly ash from coal-fired power plants has increased year by year, becoming one of the largest industrial wastes in my country. If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to human beings and organisms. However, fly ash can be utilized as a resour...
