水稻设计栽培系统的研制与实现

Development and realization of the rice design cultivation system

为了进一步促进水稻精确定量栽培新技术的信息化,使其便于推广应用,在总结和提炼水稻定量栽培理论与技术成果的基础上,运用系统学方法和面向对象设计思想,采用数据库技术,集成水稻生育进程、群体指标、栽培管理和叶色诊断等方面的知识模型,建立了具有时空适应性的水稻设计栽培系统。该系统实现了针对不同生态环境和不同种植方式的目标产量结构、生育进程、群体质量指标,以及密度、施肥、灌溉等农艺措施的设计,并具有输入简便、输出模式多样、易用性强等特点。用多年多点的数据对系统进行验证,按系统设计方案实施后的田间水稻产量和生长发育指标与设计值基本吻合。

To further promote the informationization of rice cultivation technology and make it user-friendly and popular,on the basis of summarizing and refining the rice quantitative cultivation theory and technology,we developed the Rice Design Cultivation System based on systematic methods,object-oriented design pattern and database technology,with integrated rice knowledge models on rice growth and developing,rice population indexes,rice cultivation and leaf color diagnosis.This system was time and space adaptable and could be used for designing object yield and yield structure,development stage,population quality indexes,population density,fertilizer application and irrigation according to specific environment factors with the features of simple input,plentiful output and easy-to-use.To verify the system,we used the data from rice productions following the solutions designed by the system at different years and locations.All of the observed yield and rice growth indexes were close to the system designed value.
