Abstract

An innovative self-compensating gated pipe system equipped with calibrated nozzles was developed in the framework of the EU project MADFORWATER no. (H2020-E.3.5.4 GA ID: 688320) to improve the performance of furrow irrigation method. The experiment was conducted in CIHEAM-Bari experimental field (Italy) on bare soil. The following performance indicators were assessed: duration of the irrigation event (IT), application efficiency (AE), distribution uniformity (DU), in addition to the volume of drainage water accumulated downstream and compared with traditional furrow irrigation. Preliminary results showed that IT decreased by one third (from 45 minutes to 30 minutes), AE and DU increased by 17% and 20% respectively. In addition, the volume of drainage water decreased by around 50%, which may positively impact the environment, especially in those countries such as Egypt where, during peak periods, drainage water is reused for irrigation. This new technique provides a cost-effective alternative to traditional surface irrigation methods with no requirement for additional energy consumption requirements for pumping drainage water into the upstream irrigation canals. Additional field tests will be carried out in different environmental contexts and on cropped areas to confirm the above reported preliminary results.
一种新型自补偿门控沟灌系统的性能评价:初步结果
在欧盟MADFORWATER项目框架内,开发了一种配备校准喷嘴的创新自补偿门控管道系统。(H2020-E.3.5.4 GA ID: 688320)提高沟灌方式的性能。试验在意大利CIHEAM-Bari试验田裸土上进行。评估了灌溉事件持续时间(IT)、施用效率(AE)、分布均匀性(DU)以及下游累积的排水量,并与传统沟灌进行了比较。初步结果表明,IT减少了三分之一(从45分钟减少到30分钟),AE和DU分别增加了17%和20%。此外,排水水量减少了约50%,这可能对环境产生积极影响,特别是在埃及等国家,在高峰时期,排水被重新用于灌溉。这项新技术为传统的地面灌溉方法提供了一种经济有效的替代方案,不需要将排水泵入上游灌溉渠的额外能源消耗。将在不同的环境背景下和在种植地区进行额外的实地试验,以确认上述报告的初步结果。
