Abstract

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%.

Key words: wheatcorn rotation, wholeprocess mechanization, technical model, optimal equipment, agricultural mechanization services

摘要： 山东省小麦玉米规模化轮作生产下机械效能未充分发挥，存在动力机械与机具配套比低、农机动力与资金浪费问题，主流的整数线性规划农机配备法不适配山东省中小型农业新型经营主体。在对小麦玉米周年轮作全程机械化技术模式调研后，对小面积耕作时农机配备模型采用增设租赁农机服务进行改进。通过验证计算，模型优化后年成本为47 922元，相比未优化前模型成本210 392元下降77.22%；农业机械的配备量下降63.63%。
