【摘要】 通过1984—1986年在宁夏回族自治区固原县三年的试验研究,运用农业系统工程学中的“最佳仿真配合法”和近代控制论中的“黑箱原理”,可以在短期内建立小麦与五项(播种量;农家肥、化肥使用量;施肥深度;保墒措施)可控生态因素的高产优化综合栽培技术数学模式,并可求得多项措施的单因子效应,综合累加效应以及有机肥与农家肥、氮与磷的最适施用量比例,使作物栽培技术向现代化,综合化、系统化、科学化方向前进了一步。更多还原

【Abstract】 A preliminary study of mathematic model of comprehensive cutivation technique of local fine wheat cultivar—Hongmangmei in Guyuan County in the years 1984—1986 was carried by using the methods and principles in agrosystems engineering. The results indicated that using the advanced science and technology can make the practical problems in agroproduction be mathematicalized, and that computer is also introduced into the study so that the simulation of mathematical model with a few field experiments can be carried out so as to obtain more information and to accelerate the progress in research and to save labour, materials and time. It has been proved by three years’ experiments that it is feasible to use the methods and princpiples of systems engineering to establish the mathematical model of the comprehensive cultivation technique of crops.更多还原
