| 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. |
