Silicon fertilizer or silicon compound fertilizer and production method thereof

Abstract

The invention discloses a silicon fertilizer or a silicon compound fertilizer containing liquid sodium silicate and a manufacturing method thereof. Mix and stir the two materials whose weight ratio is liquid sodium silicate: humic acid = 0.5-3:1, then granulate and dry to obtain the silicon fertilizer of the present invention. According to the weight ratio of silicon fertilizer: silicon fertilizer: nitrogen fertilizer: phosphorus fertilizer: potassium fertilizer: trace elements = 10-35%: 30-35%: 20-35%: 10-25%: 1%, the various materials Mix and stir to obtain the silicon compound fertilizer of the present invention. The silicon fertilizer and silicon compound fertilizer of 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, improving soil and the like. The production process of the product is simple and the fertilizer efficiency is high.

Description

technical field [0001] The invention belongs to compound fertilizers, and relates to a silicon fertilizer or 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 newcomer 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. [0003] The prior art also ha...

[0003] The prior art also has sodium silicate (Na 2 SiO 3 ) directly used as silicon fertilizer, but subject to conditions

If solid sodium silicate is used, the solid sodium silicate itself is easy to agglomerate, which is inconvenient to use; if liquid sodium silicate is used, it will cause inconvenience in transportation and use
