Silicon fertilizer and preparation method thereof

Abstract

The invention provides a silicon fertilizer and a preparation method thereof. The fertilizer includes, by weight, 10-40 parts of monosilicic acid, 15-40 parts of seaweed extract, 5-10 parts of potassium sulfate, 3-8 parts of calcium phosphate, 3-5 parts of magnesium sulfate, 4-8 parts of zinc sulfate, 1-3 parts of copper sulfate and 0.1-0.5 part of rare earth, and is prepared by high-temperature extraction, decocting, stirring and sub-packaging. The fertilizer can improve soil, can correct soil acidity, improve soil salt base, promote decomposition of organic fertilizers, and inhibit soil pathogens. The fertilizer can improve crop quality, such as fruit sugar content increase, potato use storage resistance, transportation resistance, thousand seed weight increase of rice and good rice taste. The fertilizer can improve crop resistance to disease and insects, improve crop lodging resistance, increase crop stress resistance, and reduce phosphatic fertilizer immobilization in soil.

Description

technical field

[0001] The invention relates to the technical field of fertilizer production, in particular to a silicon fertilizer and a preparation method thereof. Background technique

[0002] At present, in the practice of silicon fertilizer production, we have clearly realized that when silicon fertilizer is used as a base fertilizer, the silicon dioxide hydrate that is easily absorbed by crops in the soil is often fixed by some substances, resulting in a hydrate that cannot be absorbed by crops. Absorbed silicate compounds prevent crops from effectively absorbing and utilizing silicon fertilizers at various growth and development stages, resulting in the easy loss of silicon fertilizers in the soil and wasting fertilizer sources. The effective silicon content is low, and the absorption effect of crops is poor. Prolonged use will harden the soil. Contents of the invention
