基于远程控制的中心支轴喷灌机水肥一体化灌溉模式构建及应用

Model Construction and Application of Center-Pivot Sprinkler in Integration of Water and Fertilizer Based on the Remote Control

摘要: 针对目前中心支轴式喷灌机和水肥一体化技术在实际应用过程中存在的一些问题，本文开发一种基于中心支轴式喷灌机远程控制和施肥控制方法，构建基于远程控制的中心支轴喷灌机水肥一体化灌溉模式，其主要由远程控制系统、恒压供水单位、流量控制单元和流量执行单元等模块组成。通过田间试验表明，远程控制中心支轴式喷灌机水肥一体化模式喷洒赫尔曼–海恩均匀度CU和分布均匀度DU分别提升5.65%和2.39%；产量提高533.8 kg/hm²。研究结果有利于指导中心支轴式喷灌机和水肥一体化技术的推广应用。

Abstract: In view of the present center-pivot sprinkler and integration of water and fertilizer model in some problems in the process of practical application, in this paper, a kind of control method and model of integration of water & fertilizer with the center-pivot sprinkler based on the remote control were made, which were made by remote control system, constant pressure water supply unit, flow control unit and flow execution unit module, etc. The field test shows that the remote control center-pivot sprinkler in integration of water and fertilizer model evenness index CU and DU increase 5.65% and 2.39% respectively. The yield increased by 533.8 kg/hm². The results of the study are helpful for guiding center-pivot sprinkler and integration of water and fertilizer technology popularization and application.
