　　为了及时、准确地给作物提供适宜的土壤水分条件，该研究利用拥有自主知识产权的土壤水分传感器、数据采集控制模块、数据传输模块、管道流量计等硬件以及自己编制的土壤墒情监测与精准灌溉控制软件，以灌溉小区为管理单元，布置土壤水分传感器与灌溉设备，实现了自动获取土壤含水量信息，根据作物不同生育期的适宜土壤水分上下限确定自动或手动启动、关闭灌溉系统；通过固定式喷灌、滴灌和渗灌方式，将水直接输送到作物根部，满足作物各生育期对水的需求，从而达到节约用水，提高产量，改善作物品质的功效。运行结果表明，该系统运行稳定、可扩展性强、低成本维护，其相对偏差与传统方法相比不到5%，是有效和适用的工具。

In order to provide suitable soil moisture conditions timely and accurately for the growth of crops, the study developed a real time soil moisture monitoring and precision irrigation systems. The hardware, which was used in this study, such as soil moisture sensors, data acquisition and control modules and so on, was designed independently with independent intellectual property rights. This system took irrigation district as the management unit to set up the soil moisture sensors and irrigation equipments, and implemented automatic acquisition of soil moisture information. The startup and shutdown of the irrigation system were controlled automatically or manually by the upper and lower limits of soil moisture in the crop growth periods. Through fixed sprinkler irrigation, drip irrigation and subsurface irrigation, the irrigation water was transformed directly into the root zone of crops to meet the demand for water in the growing periods of the crop, which greatly saved water, increased crop production, and effectively improve crop quality. This system was running stability, good extensible and cost efficient, its relative deviation with the conventional method was less than 5%, which made it an effective and applicable tool.
