Abstract

The invention discloses silicon-magnesium powder and a soil conditioner containing the same as well as a preparation technology and application of the soil conditioner. The silicon-magnesium powder is a product obtained after waste residues of magnesium sulfate production are processed, and is used for preparing the soil conditioner; the soil conditioner containing the silicon-magnesium powder comprises the following raw material components in parts by weight: 5-20 parts of silicon-magnesium powder, 10-20 parts of light calcined magnesia, 30-45 parts of bentonite, 5-15 parts of zeolite, 25-40 parts of magnesite, and 5-20 parts of talc. The preparation technology of the soil conditioner containing the silicon-magnesium powder comprises the steps of blending, smashing, pelletizing, screening and packaging. The soil conditioner containing the silicon-magnesium powder, provided by the invention, has excellent disintegrating property, fully utilizes the waste residues of magnesium sulfate production, realizes waste recycling, can neutralize acidic compounds in soil, improves soil property, and supplements medium elements in soil, the water and fertility retention are realized, the soil hardening problem can be solved, and the soil conditioner can be applied to the field of fertilizers.

Description

technical field [0001] The invention relates to the technical field of soil conditioners, in particular to silicon magnesium powder, a soil conditioner containing silicon magnesium powder, a preparation process and application thereof. Background technique [0002] At present, magnesium sulfate manufacturers have always adopted the traditional magnesium sulfate production process. The raw materials used to produce magnesium sulfate are light-burned magnesia and sulfuric acid. Most of the light-burned magnesia reacts with sulfuric acid in the reactor, and the remaining light-burned oxidized The mixture of magnesium and other substances that do not react with sulfuric acid is called magnesium sulfate production waste. The water content of magnesium sulfate production waste residue is generally in the range of 20% to 40%, which is very sticky and not suitable for drying treatment, so magnesium sulfate manufacturers will accumulate a large amount of magnesium sulfate production ...
