摘要
现代化农业对作物生长微环境要求高,对灌水时间、灌水量、灌水部位、水肥营养供给等都有更精确要求,自动化灌溉控制工程技术正是支撑现代化农业的一项基础性技术措施。为此,山东省水科院技术人员,经过多年来的技术开发与工程实践,集成电子信息技术、远程测控网络技术、计算机控制技术及信息采集处理技术,通过计算机通用化和模块化的设计程序,构筑供水流量、压力、土壤水分、作物生长信息、气象资料的自动监测控制系统,进行水、土环境因子的模拟优化,实现灌溉节水、作物生理、土壤湿度等技术控制指标的逼近控制,从而将农业高效节水的理论研究提高到现实的应用技术水平。该项技术已针对山东省不同种植作物、不同灌溉措施进行了系列推广,逐步形成了一套成熟的完整的应用技术体系。
Modernized agriculture has high demand on crop growth microenvironment, irrigation time, quantity, control zoon, and water-fertilizer regime, while automatic irrigation control engineering technique is a foundational support to realize agricultural modernization. The authors have been researching in technique development and application of integration electronic information, remote monitoring network, computer control and information acquisition and processing to develop computer universal and modular design program to construct water supply discharge, pressure, soil moisture, crop growth, meteorological data monitoring system. The objectives of the study include land and water environment factors simulation and optimization, crop physiology, soil moisture control to apply the agricultural high-efficiency water-saving theory in practical uses. Currently, the technique has been extended to the different crops and different irrigation methods of the province to form an application system of well-rounded and complete technique.
