The Research On Intelligent Management And Decision System On Rice In Shandong

About the paddy rice simulation technology, domestic and foreign had the massive reports, at present domestic has researched and developed successful WCSODS (wheat cultivation simulation optimization decision system), the paddy rice production regulation system or the paddy rice managed the expert system the research also to yield many results, this research was studies in the foundation in the predecessor, according to the crops physiology ecology theory, embarked from the crops production mechanism, establishes the paddy rice community dynamic (to do material, leaf area index and community total stem number including community) the analog modeling, according to paddy rice cultivation optimization principle, The establishment paddy rice most suitable community dynamic model (including most suitable community photosynthesis production, most suitable community leaf area index and most suitable community total stem number) the analog modeling as well as the paddy rice cultivation optimization mathematical model (most suitable output model, suitably applies fertilizer policy-making model); Is suitable for the Shandong paddy rice growth period soil nitrogen dynamic model according to the soil nitrogen equilibrium and the transformed principle establishment. Uses Shandong separately the meteorology, the soil, the variety material debugging determination parameter, the examination and the confirmation model, then unifies the paddy rice growth growth simulation and the paddy rice cultivation optimized principle, conducts the paddy rice production decision-making research take the optimized model analogue result as the goal, the development forms the Shandong paddy rice intellectualization management decision system. Main findings as follows:1. The establishment paddy rice community did the matter dynamic model...
