The invention discloses a treatment method of a composite
raw material for crops, the
raw material of the formula is natural ore, and the natural ore is a mixture of medical stone,
smithsonite,
pyrolusite,
copper concentrate and paigeite. The preparation method comprises the following steps: crushing natural ore into
powder, carrying out vibration screening, suspension separation, soaking, dissolving and boiling reaction, aging extraction and
filtration to prepare a multi-element ore solution, then carrying out ultrasonic
field energy-gathered shearing driven by an alternating high-intensity
magnetic field, and finally carrying out aging
filtration, purification and filling. The invention relates to the technical field of compound fertilizers, in particular to a method for preparing a compound
fertilizer, seeds are cleaned, the cleaned seeds are soaked in a treating agent for 3-5 days, and the method relates to the technical field of compound fertilizers. According to the treatment method for the composite raw materials for the crops, the inner wall of the shell can be cleaned in time after the device stops stirring, and the
brush head can be protected when the device is used for stirring.
