| 摘 要： | 本研究旨在解决传统灌溉农业的“水氧矛盾”和根系的“向水追氧”两大农业难题，应用现代水肥耦合和增氧灌溉技术，设计了一种水肥气高效耦合灌溉系统。通过应用灌溉系统对水稻、黄瓜等作物的栽培试验证明：相比于常规灌溉方式，水、肥、气耦合灌溉能促进作物根系生长和提高根系活力，使其能最大限度地从土壤中吸收水分和养分，进一步挖掘和提高作物自身生产力，提高水肥利用效率，增产提质，同时也为从根源上缓解农业面源污染提供一种新途径。

Design and Experiment of an Efficient Coupling Irrigation System of Water-fertilizer and Gas |
| |
| Abstract: | The aim is to solve two problems in traditional irrigation agriculture, which are“water oxygen contradictions”and“root system grow to moisture and oxygen”. With the application of modern technology of water and fertilizer coupling and aerated irrigation, an efficient water, fertilizer and gas coupling irrigation system was designed. The cultivation experiments of rice, cucumber and other crops were carried out by applying oxygation system. The results showed that compared with conventional irrigation, water-fertilizer and gas coupling irrigation could promote crop root growth and increase root activity, which could maximize the absorption of water and nutrients from the soil and increase crop productivity, so the system could not only improve water and fertilizer use efficiency and yield, but also provide a new way for alleviating the agricultural non-point source pollution from the source. |
