在界定农机配套服务的基础上,首先系统分析了农机配套服务的影响因素,以黑龙江垦区51个农场近10年农机和粮食产量等数据为例,采用相关分析、建立最优模型等方法知目前黑龙江垦区农机配套比与粮食单产相关系数的绝对值存在逐年减少趋势.再以七星农场近10年数据为例知小型农机具配套比与粮食产量相关性最密切,而利用建立最优回归模型揭示大中型拖拉机配套农机具对粮食产量起到显著作用.最后建立和分析农机配套服务的协调优化模型,确定了决策变量的满足条件,为推进农机配套服务具有重要意义.
Based on the definition of supporting services for agricultural machinery, the paper first systematically analyzes the influencing factors of supporting services for agricultural machinery. Taking the data of agricultural machinery and grain yield of 51 farms in Heilongjiang Reclamation for nearly 10 years as an example, the author uses correlation analysis and optimal model to know the current The absolute value of the correlation coefficient between agricultural machinery matching and grain yield in Heilongjiang reclamation area tends to decrease year by year.Considering the data of the past seven years in Qixing Farm as an example, we know that the correlation between the matching ratio of small agricultural machinery and grain yield is the most close, and the establishment of optimal regression model Large and medium-sized tractors supporting agricultural machinery plays a significant role in grain yield.Finally, the paper establishes and analyzes the coordination and optimization model of agricultural machinery supporting services and determines the conditions for meeting the requirements of decision-making variables, which is of great significance for promoting agricultural machinery supporting services.
