Silicon fertilizer and production method thereof

Abstract

The invention relates to a silicon fertilizer and a production method thereof, belonging to the field of plant fertilizers and production methods thereof. The silicon fertilizer contains the followingmaterials in parts by weight: 39.4 parts of bentonite, 30.3 parts of pulverized coal ash, 30 parts of sodium hydroxide liquid caustic soda containing 30 percent of alkali, 0.25 part of catalyst magnesium oxide and 0.05 part of aluminium oxide. The production method of the silicon fertilizer comprises the following steps: processing the pulverized coal ash by an all-powerful pulverizer; putting 50parts of the processed pulverized coal ash, 49.5 parts of sodium hydroxide solutions containing 30 percent of the alkali, 0.416 part of the magnesium oxide and 0.084 part of the aluminium oxide intoa double-helix conical mixer to form soluble silicon fertilizer materials; placing the silicon fertilizer materials into a cement material pool; then putting 60.6 parts of the silicon fertilizer materials and 39.4 parts of the bentonite into a double-shaft horizontal type mixer for mixing, and then putting the mixture into a granulating disc; putting the dried silicon fertilizer into a cooler to enter a sieving machine for being sieved; and circularly producing the silicon fertilizer. The silicon fertilizer enhances the air permeability of soil, regulates the pH value of the soil, plays a soilimprovement role and is suitable for the fertilization of various crops.

Description

technical field [0001] The invention belongs to a plant fertilizer and a production method, in particular to a silicon fertilizer and a production method. Background technique [0002] At present, available silicon (SiO 2 ) content is only 10-20% low, and the raw material used in most silicon fertilizers is blast furnace steel slag, which is slow to absorb by plants after fertilization and cannot achieve the ideal effect of silicon fertilizer. It cannot make plants fully absorb nutrients, increase crop yield, improve soil, plant disease resistance, antibacterial, anti-virus ability, and prevent lodging. In addition, although a silicon fertilizer transformed from silica sand and sodium carbonate has a good effect in the process of plant absorption and utilization, its production cost is high, and the transformation temperature needs to be around 1400°C, which requires a long transformation time and wastes energy.
