“七五”期间国内具有代表性的作物生产计算机模拟系统主要有四种类型,与国外系统相比,国内各系统具有实际运用的价值,但由于大多是建立在经验模型基础之上,而很少是建立住作物生长发育规律基础之上,因而解释机理和预洲功能较差。作物生产模拟技术目前还在进一步深化,从发展趋势来看,新的模型系统必须要建立在作物本身生长发育规津及其对环境资源合理利用的基础上,最终形成一种机理性的动态模型。 During the “Seventh Five-year Plan” period, there are mainly four types of computer simulation systems for crop production in China. Compared with foreign systems, domestic systems have practical value. However, most of them are based on empirical models, Less is to establish the law of growth and development of crops based on the interpretation of the mechanism and the pre-Chau poor. Crop production simulation technology is still further deepening, from the perspective of development trend, the new model system must be based on crop growth and development regulations and their rational use of environmental resources on the basis of the final formation of a dynamic model of the .
