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...
