[0016] Beneficial Effects

[0017] The invention provides a nano-magnetic complex fertilizer synergist. The magnetic fertilizer of the invention can improve the physical properties of the soil, reduce the soil bulk density, improve the soil micro-aggregate structure, improve the soil permeability, enhance the soil's drought and waterlogging resistance, and at the same time increase the ground temperature. This process helps to optimize the crop growth environment and promote the healthy development of plant roots. Secondly, the magnetic fertilizer also shows significant advantages in chemical properties. It can effectively reduce the acidity of the soil, promote the effective transformation of nutrients, increase the cation exchange capacity, reduce the adsorption of phosphate in the soil, and increase the adsorption capacity of heavy metal ions. These chemical changes are conducive to the rational use of nutrients and improve the crop absorption efficiency. In addition, the promotion effect of the magnetic fertilizer on soil biological activity cannot be ignored. It can increase the activity of phosphatase, invertase, amylase and catalase in the soil, create favorable conditions for the activities of microorganisms, promote the health of the soil ecosystem, and then indirectly promote the growth and development of crops. Finally, the direct promotion effect of the magnetic fertilizer on crop growth is also obvious. It can effectively promote seed germination and accelerate plant growth. DETAILED DESCRIPTION
