Problems solved by technology

[0002] The current fertilizer classification method in my country is to divide fertilizers into three types: fertilizers with large elements, fertilizers with medium elements, and fertilizers with trace elements. Silicon fertilizer belongs to a kind of fertilizer with medium elements and is a good quality fertilizer. It can be used as a fertilizer to provide nutrients, and can be used as a soil conditioner to improve the soil. In addition, it can prevent diseases, prevent insects and attenuate viruses. It is an efficient and high-quality fertilizer for the development of green ecology. In recent years, water-soluble silicon fertilizers have developed rapidly. Most of the existing water-soluble silicon fertilizers use water glass (aqueous solution of sodium silicate or potassium silicate) as raw material for foliar fertilization, but water glass has a significant disadvantage when used as silicon fertilizer: silicate anions are prone to aggregation The reaction produces large aggregates, which is aging. After the water glass is aged, the particle size increases, and even if it is diluted with water, it cannot be dissociated into small particles, which are difficult to be absorbed by plants, and the fertilizer efficiency becomes poor.

Embodiment 1

[0010] Embodiment 1: the water-soluble negative ion silicate fertilizer of the present embodiment is made up of the raw material of following weight ratio: sodium carbonate 30%, calcium carbonate 5%, sodium citrate 5% and silica powder 60%, preparation method is: at first pure Natural silica is crushed into silica powder to ensure that the particle size of the silica powder is above 400 mesh, then add sodium carbonate, calcium carbonate and citric acid in the weight formula, mix and stir evenly, and put it into a high-temperature furnace above 1650°C for melting. The high-temperature melting time is more than 4 hours. After melting, the mixture is put into water to cool, and after cooling, the finished product can be taken out and dried for packaging.

Embodiment 2

[0011] Embodiment 2: the water-soluble negative ion silicate fertilizer of the present embodiment is made up of the raw material of following weight ratio: sodium carbonate 25%, calcium carbonate 8%, sodium citrate 8% and silica powder 59%, preparation method is: at first pure Natural silica is crushed into silica powder to ensure that the particle size of the silica powder is above 400 mesh, then add sodium carbonate, calcium carbonate and citric acid in the weight formula, mix and stir evenly, and put it into a high-temperature furnace above 1650°C for melting. The high-temperature melting time is more than 4 hours. After melting, the mixture is put into water to cool, and after cooling, the finished product can be taken out and dried for packaging.

Embodiment 3

[0012] Embodiment 3: the water-soluble negative ion silicate fertilizer of the present embodiment is made up of the raw material of following weight ratio: sodium carbonate 28%, calcium carbonate 8%, sodium citrate 8% and silica powder 56%, preparation method is: at first pure Natural silica is crushed into silica powder to ensure that the particle size of the silica powder is above 400 mesh, then add sodium carbonate, calcium carbonate and citric acid in the weight formula, mix and stir evenly, and put it into a high-temperature furnace above 1650°C for melting. The high-temperature melting time is more than 4 hours. After melting, the mixture is put into water to cool, and after cooling, the finished product can be taken out and dried for packaging. The water-soluble negative ion silicic acid fertilizer prepared in embodiment 1, embodiment 2 and embodiment 3 is applied simultaneously in three equally divided paddy fields, wherein the paddy field yield of the fertilizer in app...

Abstract

The invention discloses a water soluble negative ion silicic acid fertilizer and a preparation method thereof and relates to the technical field of farm-oriented fertilizers. The water soluble negative ion silicic acid fertilizer is prepared from the following raw materials in percentages by weight: 25-35% of sodium carbonate, 3-8% of calcium carbonate, 3-8% of sodium citrate and 55-65% of silica powder. The water soluble negative ion silicic acid fertilizer is prepared from various natural raw materials which affect one another in function and are synergic one another. The added components can be used as nutrients of plants, so that the water soluble negative ion silicic acid fertilizer is safe and environment-friendly, can promote growth of crops, is free of any toxic and harmful effects on crops, and is easy to absorb by plants, and the fertilizer efficiency can be improved.
