中文摘要：
在地下滴灌条件下,作物根系集中在滴头周围生长,易于出现缺氧症状,针对这一问题,运用对照处理方法,研究了加气灌溉对番茄生长发育及产量等方面的影响,并对不同灌水水平下的加气灌溉进行了比较。结果表明,加气处理均可促进番茄生长提高产量,但优果率不高。其中,相较于对照,相同灌水量加气灌溉对开花时间影响不大,但增高13.90%,增粗4.13%,增产28.52%。加气灌溉条件下（kcp=0.8）更利于促进温室番茄生长,提高产量。以上研究结果为加气灌溉灌溉技术推广应用提供了理论依据。
英文摘要：
According to the fact that under SDI condition,a part of the root zone is purged of soil water and therefore experiences insufficient oxygen for root.This study is conducted to evaluate the effects of aerated subsurface irrigation with different amount of irrigation on the growth and physiological characteristics of tomato in greenhouse.By comparison,the results show that under the same amount of irrigation,the aerated subsurface irrigation treatments can increase the height by 13.90%,the diameter by 4.13% and the yield by 28.52%.And the aerated subsurface irrigation with the kcp factor equal 0.8 is the most suitable.The results provide a theoretical basis for the application and promotion of aeration irrigation technology.
