南疆冬小麦精确灌溉决策系统的研究

Study on Precision Irrigation Decision System of Winter Wheat in Southern Xinjiang

为了实现南疆冬小麦的精确灌溉,开发了南疆冬小麦精确灌溉决策系统。系统主要由天气、信息、决策、土壤信息、统计等模块构成。其中结合南疆冬小麦快速生长的水分条件及专家实地考察的实际结果,同时以彭曼-蒙特斯公式为核心、水分平衡方程为基础,运用天气数据和土壤详细信息构建了南疆冬小麦灌溉管理的数学模型决策模块。系统实现了精确灌溉的实时动态决策,为冬小麦的节水和精确灌溉提供重要的参考,具有实际意义,为冬小麦生产智能化提供决策支持。

In order to achieve the precise irrigation of winter wheat in southern Xinjiang,a precise irrigation decision system for winter wheat was developed in southern Xinjiang.The system is mainly composed of the modules of weather,information,decision-making,soil information and statistics.Combined with the water conditions of the rapid growth of winter wheat in southern Xinjiang and the actual results of field investigation by experts,and based on the Penman-Montes formula as the core and the water balance equation as the basis,the mathematical model decision module of irrigation management of winter wheat in southern Xinjiang is constructed by using weather data and soil details.This system realizes the real-time dynamic decision of accurate irrigation,provides important reference for saving water and accurate irrigation of winter wheat,has practical significance,and provides decision support for intelligent production of winter wheat.
