| 摘 要： | 根据根、冠间相互作用机制及其对土水环境响应特征，建立了以土壤水分为参变量的根、冠关系模拟调控模型，并基于常规及适应跟踪控制思想，给出了2种计算作物需水量、规划灌溉方案的方法. 作为例子，分别计算出了1992、1994两年冬小麦生长季内逐日1m土体应具备的水量，模拟值与实测值经统计相关检验，均达到了极显著水平.实验证明，两种方法可用来根据不同生产目标，制定农田灌溉方案。

| Abstract: | The simulation and control models are established based on the mechanism of root-shoot interaction. The modeling of crop water requirement is discussed by using output error estimation method. Two methods for calculating the amount of crop water requirement are proposed. The simulationis fitted well with measured data. The results indicate that these two methods can be used in designing of irrigation scheme for different productions. |

| Keywords: | irrigation scheduling adaptive tracking control crop growth relations of root and shoot |
