The invention discloses a preparation method of a plant growth nutrient solution, which mainly comprises the following steps: crushing lignite, adding sodium hydroxide solution, centrifugally separating the extractive solution to remove residues, adding hydrogen peroxide to oxidize and activate into an activation solution, then adding a composite precipitant consisting of hydrochloric acid solution and PAM solution, precipitating and separating to remove brown and black humic acid, and vacuum concentrating the clear solution to obtain a concentrated fulvic acid FA solution, putting the concentrated solution into a reaction kettle, adding an amino carboxyl complexing agent and other raw materials for reaction, and then adding condensed water into another reaction kettle respectively. After being dissolved, the mixture is evenly mixed in turn to obtain the plant growth nutrient solution. The invention takes humic acid, nitrogen, phosphorus and potassium compounds, trace elements and additives as raw materials, and makes the plant growth nutrient solution through a scientific compounding process. After dilution with water, the product can be used for seed soaking, root soaking and foliar spraying. It can not only provide crops with nitrogen, phosphorus, potassium and a variety of medium and trace elements, but also has many functions and functions such as improving soil, improving fertilizer utilization rate, regulating crop growth, improving crop stress resistance, improving pesticide efficacy and improving agricultural product quality.
