Embodiment 1

[0021] The production method of the magnetized high-silicon iron tailings composite soil restoration fertilizer of the present invention comprises the following steps:

[0022] A. Prepare high-silicon iron tailings and carry out magnetization treatment on high-silicon iron tailings. The magnetization intensity is 800GS-2000GS. Through magnetization treatment, the activity, water solubility and citrate solubility of silicon element are improved, and it becomes effective agricultural silicon;

[0023] B, with the effective agricultural silicon obtained in step A, according to the effective agricultural silicon of 75-95 parts by weight, add 5-8 parts by weight of nitrogen fertilizer or nitrogen, phosphorus and potassium compound fertilizer, heavy metal ion remover of 3-7 parts by weight, 2- The ratio of the plant growth regulator of 6 parts by weight and the plant-based adhesive of 2-5 parts by weight is to add nitrogen fertilizer or nitrogen, phosphorus and potassium compound fer...

Abstract

The invention relates to a production method of a magnetized high-silicon iron tailings compound soil remediation fertilizer. The production method comprises the following steps: mixing and stirring the following raw materials in parts by weight: 75-95 parts of effective agricultural silicon, 5-8 parts of nitrogen fertilizer or nitrogen-phosphorus-potassium compound fertilizer, 3-7 parts of heavy metal ion removing agent, 2-6 parts of plant growth regulator and 2-5 parts of plant type adhesive; and then performing crushing treatment. The production method disclosed by the invention is simple in production process, low in energy consumption, low in cost, large in tailing use amount, and can perform innocuousness treatment on high-silicon iron tailings; the obtained product magnetized high-silicon iron tailing compound soil remediation fertilizer can yield-increasing effect on the crop after being applied, raises the EH value of the soil, increases the stress resistance of plants, improves the physical and chemical properties of the soil, and has good remediation effect on arable land polluted by heavy metals; and the high-silicon iron tailings is fully developed and utilized, so that economic benefits and environment pollution is reduced..

Description

technical field [0001] The invention relates to a production method and product of magnetized high-silicon iron tailings composite soil restoration fertilizer. Background technique [0002] The existing high-silicon iron tailings are not fully developed and utilized, which not only leads to waste of resources, but also causes pollution to the environment. For this reason, the country's 12th Five-Year Plan for Tailings Utilization puts the harmless agricultural use of tailings as the top priority. In addition, some existing cultivated lands are polluted by heavy metals or the soil lacks the necessary elements for plant growth, resulting in problems in the yield and safety of crops, which are difficult to solve by using existing technologies. Contents of the invention [0003] The purpose of the present invention is to provide a simple production process, low energy consumption and low cost, which can be used for harmless treatment of high-silicon iron tailings. The use of ...
