| 摘要: |
| 地下滴灌加气技术是通过地下滴灌管网加气来改善根区土壤通气条件，避免低氧胁迫对作物造成不利影响，促进作物增产提质的一项新型灌溉技术。目前，明确不同条件下地下滴灌加气技术的实施效果、确定适宜的加气模式与配套设备是推动该技术规模化应用的关键。本文通过凝练近年来地下滴灌加气技术的相关研究进展与成果，全面总结了作物生长适宜的根区土壤氧气值以及地下滴灌加气技术对土壤环境与作物生长的改善效果，并重点探讨了加气模式与加气设备的应用现状、存在问题和发展趋势。可为读者快速、详尽地了解地下滴灌加气技术研究进展提供参考。目前，地下滴灌加气技术在作物产量与品质提升方面效果显著，但仍存在进一步研究和解决的问题，首先是作物需按时按需加气，其次需要从“气源-灌溉系统-土壤环境-作物生长”全过程提升加气综合利用效率并研发实用、高效的地下滴灌专用加气设备。 |

| Abstract: |
| Subsurface drip irrigation aeration technology is a new irrigation technology to improve soil aeration conditions in root zone, avoid adverse effects of hypoxic stress on crops, and promote crop yield and quality improvement through subsurface drip irrigation network aeration. At present, the key to promote the large-scale application of subsurface drip irrigation aeration technology is to clarify the implementation effect of subsurface drip irrigation aeration technology under different conditions and determine the appropriate aeration mode and supporting equipment. Subsurface drip irrigation is based on the concise in recent years the aerated technology related research progress and results, comprehensive summary of crop growth subsurface drip irrigation is suitable for root zone soil oxygen value and aerated technology on soil environment and improve the effect of crop growth, and probes into the gas mode and the present situation of the application of gas equipment, problems and development trend. It can provide reference for readers to understand the research progress of underground drip irrigation aeration technology quickly and in detail. At present, the technology of the underground drip irrigation aerated in crop yield and quality improvement effect is remarkable, but there are still further study and solve the problem, first of all to be on time and on-demand aerated crops, you need the from "air - irrigation systems - soil environment, crop growth" promote the gas comprehensive utilization efficiency and the whole process of subsurface drip irrigation is practical, efficient dedicated gas equipment. |
