Research on Crop Sales Optimization Method Based on BP Neural Network Big Data Simulation

This paper mainly studies the optimal strategy for crop planting. First, an optimization model for crop planting is established. The model takes the maximum total profit of crop planting as the objective function, and the constraints are that the crop planting area cannot exceed the total land area, crops cannot be planted repeatedly, beans are rotated, and the planting area of each crop should not be too small. Then, combined with big data, the BP neural network is used to simulate and solve the optimization model, and the maximum profit of crop planting in the next 7 years is obtained. This model can maximize the benefits of crops and promote the prosperity and development of the rural economy under the premise of ensuring the sustainability of the ecological environment.
