Research on multi-scenario crop cultivation profit optimisation model based on genetic algorithm

This paper takes into account the constraints of no repetition crops,non-dispersed planting, planting area not being too small, and planting legumes at least once in every three years on all land in each plot, taking into account the substitutability and complementarities of various crops, crop substitution and bundled planting based on the characteristics of the crops, and further considering the uncertainties and potential risks as well as the correlation between the expected sales volume and sales price and the cost of planting .Then establish an optimisation model to provide planting guidance strategies to maximise profits. Using genetic algorithm to solve the model, the maximum profit from 2024 to 2030 is 2.212 million yuan, which is an average increase of 34% compared to the 2023 profit.
