Abstract

The invention relates to the technical field of agricultural soil improvement, in particular to a preparation method of a macromolecular soil improving agent. The macromolecular soil improving agent is prepared from 40 to 60 mass parts of active calcium carbonate powder, 20 to 30 mass parts of potassium acrylate, 15 to 20 mass parts of styrene, 6 to 8 mass parts of 2, 4-ethylene diene dimethyl ester, 3 to 5 mass parts of pH regulators, 10 to 20 mass parts of auxiliary agents, 3 to 5 mass parts of initiators, 4 to 6 mass parts of reducing agents and 100 to 200 mass parts of water and 60 to 80 mass parts of strong acid. A macromolecular reticular structure is formed on the surface of active calcium carbonate powder; strong acid is used for dissolving active calcium carbonate for preparing the hollow reticular macromolecular structure; after the use, soluble ions and heavy metal ions can be adsorbed to form solid particles insoluble in water, so that the effects of reducing the contents of salt and heavy metal in soil of kaline soil and improving the soil can be achieved.

Description

Technical field [0001] The invention belongs to the technical field of agricultural soil improvement, and specifically relates to a preparation method of a macromolecular soil amendment. Background technique [0002] In recent years, with the excessive development of China’s animal husbandry and the excessive use of pesticides and fertilizers, China’s soil environment has been greatly destroyed, and problems such as soil salinization and heavy metal pollution have emerged one after another, and soil salinization and heavy metals have seriously exceeded the standard. , Which seriously affects China’s food security issues, and most of the soil amendments that have emerged today can only improve the fertility of the soil to a certain extent, but cannot remove heavy metals in the soil and improve the fertility of saline-alkali soils, and cannot satisfy people’s needs. Therefore, it is very important to invent a substance that can improve the soil well. [0003] Chinese patent applicat...
