Silicon fertilizer, silicon compound fertilizer and production method thereof

Abstract

The invention discloses a silicon fertilizer, a silicon compound fertilizer and a production method thereof. The production method consists of: mixing liquid sodium silicate and humic acid in a weight ratio of 0.5-3:1, then conducting granulation and drying to obtain the silicon fertilizer; then mixing the silicon fertilizer, a nitrogen fertilizer, a phosphate fertilizer, a potassium fertilizer and trace elements according to a weight ratio of 10-35%:30-35%:20-35%:10-25%:1%, thus obtaining the silicon compound fertilizer. The silicon fertilizer and silicon compound fertilizer provided by the invention are easily soluble in water, have high effective silicon content, are easily absorbed by plants, and have the advantages of enhancing plant resistance, increasing yield, improving quality, and improving soil, etc. The production process of the products is simple, and the fertilizer efficiency is high.

Description

technical field [0001] The invention belongs to compound fertilizers, and relates to a silicon fertilizer, a silicon compound fertilizer and a production method thereof. Background technique [0002] As we all know, silicon is the fourth most important element for crop growth after nitrogen, phosphorus, and potassium, and silicon fertilizer is a rookie among chemical fertilizers. Existing silicon fertilizers are usually mineral fertilizers mainly containing calcium silicate, which can be made directly from fly ash or phosphate rock tailings. Although the silica SiO in fly ash or phosphate rock tailings 2 The content can be as high as 50-60%, but soluble silicon only accounts for 1-2%, which is not easy to be absorbed and utilized by plants, resulting in a large amount of silicon fertilizer and poor fertilizer efficiency. Therefore, increasing the soluble silicon content has become the key to improving the efficiency of silicon fertilizer. Contents of the invention [00...
