灌区灌溉制度自动化设计

Automation Design of Irrigation System in Irrigation Area

以国内外常用的水量平衡法为基础,研究并掌握作物与水的关系及在不同生育过程中的作用,针对不同作物的需水特点及各生态类型区的供水条件,结合前人研究经验与农业灌溉设计人员的设计习惯,对制定灌溉制度的方法和所需参数进行研究。利用access建立数据库,通过Net Framework平台上的Visual Basic.NET编程语言进行程序化设计;通过更新、调用数据库,结合灌区蒸发、入渗等参数,利用程序按照不同生长期进行自动计算;将计算结果自动绘制整个生长期内的灌水图,简化运算过程,实现灌溉制度的自动化。

Based on water balance method commonly used at home and abroad,the relationship between crop and water and effect in different process were studied,according to different crop water demand characteristics and water supply conditions in various ecological types,combined with the design experience of scholars and habits of agricultural irrigation designers,the methods for formulating irrigation system and the required parameters were studied.Using access to establish database,Visual Basic.NET on the platform of Net Framework was adopted to conduct program design;by updating and calling the database,combined with evaporation,infiltration parameters in the irrigation area,automatic calculation was conducted by the program according to different growth stages;the irrigation map of the whole growth period was drew by calculation results,the process was simplified,and automation of irrigation system was realized.
