水稻生产是由“天——田——禾——人”构成的多目标系统。传统的作物栽培,往往是凭经验和单项措施,对这个系统进行控制。由于作物生产活动总是围绕一定的技术和经济目标进行,并受社会、经济和自然条件的制约,因此应用传统方法,很难从整体出发,确定系统的定量的技术方案和经济目标。近年来,随着系统原理和电子计算机的应用,这既有可能通过对生产过程的模拟、寻优和对多目标系统进行综合研究,又有可能逐步实现最佳技术方案的定量化。
Rice production is a multi-objective system composed of “Tian-Tian-Wo-Man”. Traditional crop cultivation is often based on experience and individual measures to control this system. Since crop production activities are always conducted around certain technical and economic goals and are subject to social, economic and natural conditions, applying traditional methods makes it difficult to determine systematically quantitative technical solutions and economic goals from a holistic perspective. In recent years, with the application of system principles and electronic computers, it is possible to realize the quantification of the best technical solutions step by step through both the simulation of the production process, the optimization and the comprehensive study of the multi-objective system.
