在总结、归纳和提炼小麦栽培理论与技术的研究成果和知识积累的基础上 ,运用系统学方法和结构化途径 ,建立了具有时空适应性的小麦栽培管理动态知识模型系统 ,用于确定不同环境条件和生产系统下的小麦生育特征及栽培管理技术方案。系统包括 :产量水平与产量结构、主要品质指标、品种类型、播种期、基本苗、播种量、适宜生育期 ;主要生育期的茎蘖数、叶龄、叶面积指数、生物量等动态指标 ;有效叶面积率、高效叶面积率和粒叶比等源库指标 ;氮、磷、钾肥料运筹及主要生育期的水分管理等。本系统克服了传统作物栽培模式与专家系统的地域性强和广适性差的不足 ,从而为实现作物栽培管理的定量化和信息化奠定了基础。
On the basis of summarizing, summarizing and researching the research achievements and knowledge accumulation of wheat cultivation theory and technology, a dynamic knowledge model system of wheat cultivation and management with time and space adaptability was established by means of systematic method and structured approach to determine different environments Wheat growth characteristics and cultivation management techniques under conditions and production system. The system includes: output level and yield structure, main quality index, variety type, sowing date, basic seedling, sowing amount and suitable growth period; dynamic indexes of stem tiller number, leaf age, leaf area index and biomass in the main growth period; Effective leaf area ratio, high leaf area ratio and grain-leaf ratio of the source library indicators; nitrogen, phosphorus and potassium fertilizer operation and the main growth period of water management. The system overcomes the shortcomings of the traditional crop cultivation model and the expert system of regional strong and wide adaptability, which laid the foundation for the quantitative and informatization of crop cultivation and management.
