摘要
针对已有作物灌溉预报中未能充分利用降雨的不足,特别是在应用实施时缺乏可操作性问题,基于实时的气象与土壤墒情监测数据,利用田间水量平衡原理和作物根系生长模拟技术,提出了充分利用降雨的实时灌溉制度模型,并用Java语言编制了网络计算机软件,以冬小麦作为研究对象,通过实验研究与软件调试,实现了对作物灌溉的远程及实时调控。该方法与软件可有效地利用当地降水资源,实现灌溉的远程管理,适合在我国北方灌区推广使用。
Aimed at the shortcomings of existing irrigation schedule research,such as lack of full use of precipitation,especially lack of exercisable implementation,based on the theory of water balance and the simulation model of crops,a real-time irrigation schedule,in which real precipitation is full taken into accounted,is proposed in this paper through using the on-line monitoring weather and soil moisture data.Then the computer language-Java is used to develop network computer software for irrigation management.The winter wheat is selected for study object,and some parameters are verified by experiments.The program and method could realize real-time remote management and control for crop irrigation,which is effective for using of precipitation,and it is suitable for used in the north of China.
