Abstract

The invention discloses an improving agent for reducing the pH value and the sodium ion content of saline-alkali land and a preparation method of the improving agent. The improving agent comprises thefollowing components in parts by mass: 90-100 parts of desulfurized gypsum, 90-100 parts of fly ash, 90-100 parts of furfural residues, and 40-50 parts of an improving auxiliary agent. According to the improving agent provided by the invention, the desulfurized gypsum, the fly ash and the furfural residues can significantly reduce the pH value of the saline-alkali soil, promote the elution of Na<+>, reduce the content of HCO3<->, and improve the content of SO4<2->, Ca<+> and Mg<+>, so that the improving effects of the saline-alkaline soil are significant; and an organic fertilizer capable ofproviding nutrients for the growth of crops is selected as the improving auxiliary agent, and therefore the soil conditions are improved while the growth of the crops is promoted.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improvement, in particular to a soil conditioner capable of improving the soil condition of saline-alkali land so that it is suitable for the growth of crops and a preparation method thereof. Background technique [0002] There are a large number of saline-alkali lands in our country. The yield of crops planted on these lands is very low, or even extinct. If no crops are planted on the saline-alkali land and left unattended, the saline-alkali land will slowly erode to the good land, and the area of ​​the saline-alkali land will become larger and larger, so Harnessing and improving saline-alkali land is a national plan and an urgent matter. [0003] Desulfurization gypsum is the waste after desulfurization in power plants, the main component is calcium sulfate, and it also contains a certain amount of water. Because it cannot be directly used as building materials and cement retarders, ...
