Optimization Research on Crop Planting Strategies Based on Linear Programming Model

Under the condition of limited cultivated land resources, optimizing crop planting strategies is of great significance for increasing the yield and quality of crops, ensuring national food security, and promoting the sustainable development of agriculture. This paper focuses on the crop planting problem and establishes a linear programming model. The mathematical form of the objective function is determined. The model takes the maximization of the total revenue of crops as the objective function, taking into account factors such as the limitations of plot types, the restrictions on continuous cropping of crops, the rotation requirements of leguminous crops, the constraints on planting area, and the prevention of overly dispersed planting areas. Through sensitivity analysis, the impact of the minimum planting area is evaluated. This model can effectively solve the problem of crop planting optimization and provides a theoretical basis for scientific planting plans.
