Abstract: The mechanical efficiency of large-scale wheat and corn crop rotation production in Shandong Province has not been fully utilized, and there are problems of the low matching ratio of power machinery and implements, waste of agricultural machinery power and capital, while the mainstream linear programming algorithm of agricultural machinery provision is not suitable for small and medium-sized agricultural new business entities in Shandong Province. After researching for annual wheat-corn crop rotation production, a model is established after improving and optimizing the conventional linear programming algorithm of agricultural machinery equipment. By calculating a wheat and corn planting cooperative in Zibo, the annual cost after the model optimization is 47 922 yuan, by 77.22% decrease compared with 210 392 yuan of the previous model. The equipped amount of agricultural machinery is decreased by 63.63%.
