运用农业系统工程原理,采取系统分析方法,选择对小麦高产影响较大的可控农机农艺因素为变量,以产量、净产值为目标函数,通过农机具引进、研制、改装、生产和多点试验分析,模拟运算,筛选出一套半精量机播为主的最佳农机农艺综合配套栽培管理技术。经四年实践,应用推广14.26万公顷(213.95万亩),创社会、经济效益1.4亿元。 Using the principles of agricultural systems engineering, adopting the method of systematic analysis, choosing the agronomic factors of the controllable agricultural machinery that have a great influence on the high yield of wheat as the variable, taking the output and the net output value as the objective functions, through the introduction, development, modification, production and multi-point analysis , Simulation, filter out a set of semi-precision machine-based best agricultural agronomy integrated cultivation and management techniques. After four years of practice, the application of 142,600 hectares (2.1395 million mu), creating a social and economic benefits 140 million yuan.
