Abstract

This study presents the development of a cloud-based, automated variable-rate fertigation system by modifying an existing hose–reel irrigation machine (HIM). A 46-m-wide HIM spraying boom was segmented into four independently controlled sections, and a 300-L fertiliser tank was mounted on the spraying cart to deliver liquid fertiliser directly into each section line. A control system, programmed in C#, was designed to automate the application of irrigation water and fertiliser. Calibration through laboratory and field tests optimised the application accuracy. A cloud-based information and communication technology platform was developed. The soil moisture data from the LSE01 sensors were transmitted via LoRaWAN to field gateways and then to the Things Network (TTN) for authentication, routing and JSON conversion. The system achieved precise irrigation and fertilisation within 15–50 mm and 80–600 L/ha, respectively, with minor errors (3–5% for irrigation, 1–3% for fertilisation). The spatial resolution improved significantly, with the lateral resolution reduced from 46 m to 10.7 m and the longitudinal resolution increased from 0.17 to 1.5 m, depending on the desired irrigation water and liquid fertiliser rates. These results demonstrate that the developed hose–reel variable-rate fertigation machine offers accurate and efficient fertigation suitable for precision agriculture.

一种新型的s型控制管卷式变速施肥机

本研究通过改进现有的软管卷灌机（HIM），提出了一种基于云的自动化可变速率施肥系统的开发。一个46米宽的HIM喷药臂被分割成四个独立控制的区段，在喷药车上安装一个300升的肥料罐，将液体肥料直接输送到每个区段线。设计了一个用c#编程的控制系统，使灌溉用水和化肥的施用自动化。通过实验室和现场测试进行校准，优化了应用精度。构建基于云的信息通信技术平台。来自LSE01传感器的土壤湿度数据通过LoRaWAN传输到现场网关，然后传输到物联网（TTN）进行认证、路由和JSON转换。该系统分别在15-50毫米和80-600升/公顷范围内实现了精确的灌溉和施肥，误差很小（灌溉3-5%，施肥1-3%）。空间分辨率显著提高，横向分辨率从46 m降低到10.7 m，纵向分辨率从0.17 m增加到1.5 m，具体取决于所需的灌溉水量和液肥用量。试验结果表明，所研制的管卷式变速施肥机可提供适合精准农业的准确、高效施肥。

期刊介绍： Human intervention in the control of water for sustainable agricultural development involves the application of technology and management approaches to: (i) provide the appropriate quantities of water when it is needed by the crops, (ii) prevent salinisation and water-logging of the root zone, (iii) protect land from flooding, and (iv) maximise the beneficial use of water by appropriate allocation, conservation and reuse. All this has to be achieved within a framework of economic, social and environmental constraints. The Journal, therefore, covers a wide range of subjects, advancement in which, through high quality papers in the Journal, will make a significant contribution to the enormous task of satisfying the needs of the world’s ever-increasing population. The Journal also publishes book reviews.
