The present invention relates to a paddy field mineral trace element soil conditioner formula and a use method. The paddy field mineral trace element soil conditioner comprises the following raw materials: a trace-element-rich mineral fertilizer, a soil conditioning agent, lime and a leaf surface blocking agent, wherein the trace-element-rich mineral fertilizer comprises more than 50 medium traceelements and rare earth elements, the content of oxides silicon, calcium, manganese, iron, magnesium, sodium, aluminum and titanium is 50% or more, and the content of beneficial rare earth elements and trace elements lanthanum, strontium, zinc, selenium, boron, barium, gallium and nickel is larger than or equal to 2500 [mu]g/g. The soil conditioner is rich in medium trace elements silicon, calcium, magnesium, molybdenum, iron, copper, zinc and the like, the pH value is 10.0-12.0, and the soil conditioner comprises the following main components in percentage by weight: more than or equal to 20.0 percent of effective calcium (CaO), more than or equal to 12.0 percent of effective magnesium (MgO) and more than or equal to 12.0 percent of effective silicon (SiO2). According to the formula and the using method of the mineral trace element soil conditioner for the paddy field, mineral fertilizer is applied, and the mineral fertilizer is rich in various trace elements and is a main component of coenzymes in plants, so that cell tissues of injured parts are effectively repaired, and the injured parts are promoted to recover physiological functions as soon as possible to grow healthily.
