不同年份地下水位大麦参数模型与产量动态模拟

Computer simulation study of barley growth parameters model and dynamic output in the years with different underground water level

本文研究了不同地下水位下大麦生长期叶面积指数、地上部各营养器官、储藏器官、总生物量干重的变化动态,植株各器官的干物质积累量和分配率,不同时期植株各器官的氮素含量和可溶性糖含量的变化动态;运用模型对大麦各器官干物质重及产量动态进行了模拟,并对模拟结果与实测结果进行了相关性分析,最后对大麦产量进行了模拟,结果得到各个不同年份不同地下水位处理大麦的产量与降水量之间存在着比较明显的负相关。

This paper studied the dynamic developments of leaf area index, dry weight of above ground vegetative organ and stored organ, total biomass. By means of the barley growth simulation model,various organs dry weight and yield of barley plants were simulated. The correlation between the observed and the simulated results was relevantly analyzed. Modeling barley yield indicated there existed significantly negative linear correlation between the yield of different years （different underground water level） and precipitation.
