运用适当的数学模型,表达一个系统的内部诸因素,以及这个系统与环境之间的定性和定量关系,并求出最佳方案,是当前研究方法发展的一种趋势。在农业方面,这种研究方法也正在被重视和运用,并取得了很好的经济效益。如美国,用计算机和其他数学方法来描述和反映环境一品种一栽培措施的相互作用,寻出作物最优生长势的最佳条件。
The use of appropriate mathematical models to express the internal factors of a system, as well as the qualitative and quantitative relationship between the system and the environment, and to find the best solution is a trend toward the development of current research methods. In agriculture, this research method is also being valued and applied, and achieved good economic benefits. For example, the United States uses computers and other mathematical methods to describe and reflect the interactions of a culture-one cultivation measure and find out the best conditions for crop optimal growth potential.
