以土壤水分为参变量的根冠系统模拟调控模型

A Simulation and Control Model of Root Shoot System with Soil Water as Control Factor

  • 摘要: 针对以往在建造各类作物生长模拟模型中,对构成作物整体功能的根、冠关系这一系统未予(充分)考虑的现状,在整体、器官水平上,探讨、分析了根、冠之间相互关系,归纳了根、冠系统各种特性,并构建了以土壤水分作为调控因子的根、冠互相藕合机制模型。模型辨识及两年冬小麦试验数据验证结果表明,该模型具有较强普适性和较高模拟预测精度,不仅能模拟预测出不同土壤水分条件下根、冠干物重,研究根、冠间互利互制消长反馈关系,而且还可根据不同生产目标规划灌溉方案。

     

    Abstract: All the characteristichs of root-shoot relation system were induced in the paper, and the control and simulation modle of the system was established according to its mechanisms at the level of organism under the frame of integrity ideas. The test results of the modd show that it can not only be used to study the root-shoot relationship under different soil water regimes, but also regulate and control crop growth or schedule irrigation.
