摘要
通过对玉米收获机发展的影响因素分析,提出我国玉米收获机发展中存在的问题:农艺与农机标准化程度低,基础理论研究水平低,机具质量差,生产企业状况差,说明了我国部分玉米收获机性能质量不过关的根本原因。在此基础上采用数学统计方法,利用最小二乘法的趋势拟合预测、N次曲线预测、指数预测法,得出了我国玉米机械化发展水平预测模型,为我国玉米机械化发展正确导向提供理论基础。
Through analyzing the influencing factors of corn harvest mechanization, the existent problems of China s corn mechanization were put forward： low degree of agronomy and agricultural machinery standardization, low level of basic theoretical research, poor equipment quality and poor condition of enterprises. The primary cause of the poor performance of some China＇s corn harvest machines was illustrated, On this basis, mathematical and statistical methods were adopted, and through using the trend fitting prediction, N curve prediction, index prediction of the least squares method, the prediction model of the development level of China＇s corn mechanization was reached, it provides a theoretical basis for the correct orientation.
