Water-soluble solid silicon fertilizer and production method and preparation device thereof

Abstract

The invention belongs to the technical field of inorganic silicon and particularly relates to water-soluble solid silicon fertilizer and a production method and a preparation device thereof. The water-soluble silicon fertilizer is prepared from, by weight, 40-60% of quick-resolving sodium silicate, 10-20% of sodium humate, 10-20% of urea, 5-10% of magnesium sulfate, 5-10% of liquid sodium silicate and 0.1-0.2% of sodium carboxymethyl cellulose, wherein the modulus of the quick-resolving sodium silicate is 2.85-3.0, the content of water-soluble silicon elements in the quick-resolving sodium silicate is calculated as 50-75% according to the content of silicon dioxide, the modulus of the liquid sodium silicate is 3.2-3.3, and the content of water-soluble silicon elements in the liquid sodium silicate is calculated as 26-27% according to the content of silicon dioxide. The content of water-soluble silicon dioxide of the water-soluble silicon fertilizer is high, the fertilizer application amount is small, the cost performance is high, the water-soluble solid silicon fertilizer can be applied as base fertilizer for plants and can also be applied to topdressing of water flush fertilizer, and the water-soluble solid silicon fertilizer can be widely applied to all soil lacking silicon.

Description

technical field [0001] The invention belongs to the technical field of inorganic silicon, and in particular relates to a water-soluble solid silicon fertilizer, a production method and a preparation device thereof. Background technique [0002] Silicon fertilizer, referred to as silicon fertilizer, is a fertilizer that is mainly composed of silicon or contains silicon. Silicon is considered by the international soil community to be the fourth plant nutrient element after nitrogen, phosphorus, and potassium. Most of the silicon needed by crops is provided by the soil, which is the second most abundant element in the soil, but there is very little silicon in the soil that can be absorbed by plants, especially with the rapid development of agriculture, crops continue to absorb silicon in the soil , resulting in a gradual decrease in available silicon in the soil. According to investigations by relevant departments, 70% of the soil in the Yangtze River Basin in my country is sh...

Problems solved by technology

[0005] The purpose of the present invention is to provide a water-soluble solid silicon fertilizer, which aims to solve the problem of poor water solubility of existing silicon fertilizers, low plant absorption rate, and large fertilization amount. It can only be used as a long-term base fertilizer and cannot be used in the silicon-loving period of plants. Foliar spraying, drip irrigation and topdressing, and the technical problems of fertilization only in acidic and neutral soil
