摘要

本研究的主要目的是评估中心支点可变速率灌溉(VRI)系统的技术和农艺性能。该研究于2015年在一块16公顷的玉米田进行。根据基于一系列土壤湿度传感器的实时监测系统提供的数据,在三个管理区安排灌溉。第一个结果证明了VRI系统对灌溉性能的潜在好处,但需要多年的比较来评估对气候变化的响应。VRI的产量与一切照旧制度相当,但灌溉量明显减少。

Technological and agronomic assessment of a Variable Rate Irrigation system integrated with soil sensor technologies
The main goal of this study was assessing the technological and agronomic performances of a centre pivot Variable Rate Irrigation (VRI) system. The study was conducted in 2015 on a 16-ha field cultivated with maize. Irrigation was scheduled in three Management Zones according to data provided by a real-time monitoring system based on an array of soil moisture sensors. First results demonstrated the potential benefits of the VRI system on irrigation performance however a multiyear comparison is requested for evaluating the response to climate variability. VRI resulted in yields comparable to the business-as-usual regime but through a noticeable reduction in irrigation volumes.
