Abstract
This invention discloses a method for constructing the topsoil layer of black soil based on bio-organic fertilizer, aiming to solve the problems of soil degradation and fertility decline in black soil. By preparing functional bio-organic fertilizer containing nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, and potassium-solubilizing bacteria, combined with soil physicochemical property testing and mathematical model optimization, scientific and precise fertilization is achieved. Specifically, this includes: measuring the nutrient content and pH value of soil and fertilizer; constructing a mathematical model to obtain optimized application parameters; and continuously improving soil fertility and productivity by dynamically adjusting the fertilizer application rate and assessing soil fertility. This reduces dependence on chemical fertilizers, improves soil structure, and increases crop yield, exhibiting environmental friendliness, precision, efficiency, and strong sustainability.
