Abstract

The invention discloses a preparation method of a high-concentration liquid silicon fertilizer in the technical field of silicon fertilizers. The preparation method of the high-concentration liquid silicon fertilizer comprises the following steps: performing raw material pretreatment, performing high temperature calcination, performing a combination reaction, performing concentration and purification, performing mixed heat preservation, and performing high-pressure homogenization. When raw material pretreatment is carried out, 60-80 parts of potassium feldspar mineral and pure water are placedtogether in an ultrasonic cleaner for cleaning, drying is performed after cleaning, the dried potassium feldspar minerals is crushed and ground, the fineness of grinding is controlled to be 70-80 meshes, the pretreatment step of the raw material is increased, the cleanliness of the raw material is improved, and thus a prepared water-soluble silicon contains relatively few impurities. Moreover, the silicon raw material is subjected to calcination and the combination reaction, the utilization rate of silicon in the silicon raw material is improved, and the use amount of the silicon raw materialcan be reduced. When the silicon fertilizer is prepared, a silicon raw material mixed solution is distilled and purified, the concentration of the water-soluble silicon in the silicon fertilizer is improved, the prepared silicon fertilizer has better effects, the use amount is less when the fertilizer is applied, and the fertilization efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of silicon fertilizer, in particular to a preparation method of high-concentration liquid silicon fertilizer. Background technique [0002] Silicon is already playing a more important role in sustainable agriculture than ever before. As the research on silicon continues to deepen, scientists, government officials and farmers around the world gradually realize the importance of silicon to plants and agriculture. Recent studies on the absorption, transportation, and shunting mechanisms of silicon fertilizers in plants have achieved rapid development and breakthroughs. At the same time, silicon has also made great progress in the study of mitigating abiotic and biological effects. [0003] There are two types of silicon fertilizers: citrate-soluble silicon fertilizer and water-soluble silicon fertilizer. Citrate-soluble silicon fertilizer refers to silicon fertilizer that is insoluble in water but can be abso...
