| 摘要: |
| 【目的】探明不同地下灌溉方式加气灌溉对温室芹菜生长及产量的影响。【方法】采用温室小区试验，设计了2种不同地下灌溉方式（地下滴灌D和地下渗灌S），每种灌溉方式均设加气灌溉A和不加气灌溉N，以畦灌（CK）作为对照，共5个处理，研究了不同处理对温室芹菜生长发育、产量、土壤水分分布及灌溉水生产效率的影响。【结果】渗灌较地下滴灌有明显增产效果，不加气情况下显著增产10.6%；加气灌溉有一定增产效果，但与不加气灌溉下产量差异不显著。与常规地下滴灌不加气处理相比，渗灌加气灌溉增产12.8%，达到显著性水平（p<0.01）。从土壤水分分布来看，在相同灌溉量情况下，渗灌0~20 cm土壤含水率较地下滴灌显著提高9.6%（p<0.05），而20~40 cm土层则较地下滴灌土壤含水率降低12.9%（p<0.05），地下渗灌的土壤水分分布更适合浅根性的温室芹菜根系水肥吸收。渗灌与地下滴灌的产量差异主要是株高差异所致，与芹菜的单株叶柄数关系不大。【结论】渗灌较地下滴灌显著提高灌溉水生产效率，且以渗灌加气灌溉的水分生产效率最高，渗灌结合加气灌溉可以实现温室芹菜节水高产。 |

| Abstract: |
| 【Objective】 We present the results of an experimental study on the growth and yield of greenhouse celery in response to different aerated irrigations. 【Method】 Pot experiments were conducted in a greenhouse with subsurface seepage irrigation (S) and subsurface drip irrigation (D). Each irrigation had two treatments: aeration (A) and non-aeration (B); the control was furrow irrigation (CK) without aeration. For each treatment, we measured the growth, yield, soil moisture distribution and water use efficiency. 【Result】 The yield under aerated subsurface seepage irrigation was 10.6% higher (p<0.05) than that under subsurface drip irrigation without aeration, and the aeration did not lead to a significant increase in yield. Compared with the drip irrigation without aeration, aerated seepage irrigation increased the yield by 12.8% (p<0.01). The moisture distribution in soil varied with irrigation method. Compared to the drip irrigation, the seepage irrigation increased the 0~20 cm water content by 9.6% (p<0.05) while reduced the 20~40 cm water content by 12.9% (p<0.05). Since celery is a shallow-rooting crop, seepage irrigation is more suitable to meet its demand for water, thereby having a high water use efficiency. The differences between yield under seepage and drip irrigations was due to the differences in plant weight rather than the petioles of each plant. 【Conclusion】 A combined use of subsurface seepage irrigation and aeration can noticeably improve the yield and WUE of greenhouse celery. |
