S275.6; [目的]探究不同土壤条件下增氧灌溉方式对作物生长、产量及养分利用的影响.[方法]以郑州黄黏土、洛阳粉黏质壤土和驻马店砂壤土为供试土壤,以常规地下滴灌为对照(CK),设置曝气灌溉(AI)与化学增氧灌溉(HP)2种增氧方式,研究了温室紫茄生长及养分利用对增氧地下滴灌的响应.[结果]与CK相比,AI和HP处理提高供试土壤中紫茄净光合速率,黄黏土、粉黏质壤土和砂壤土下分别增加19.66％和8.49％、14.02％和7.51％、10.13％和5.91％.同时,AI和HP处理均显著促进根系生长、提升根系活力,进而提高紫茄的养分吸收效率、产量和水分利用效率(P<0.05).其中,黄黏土下AI和HP处理作物氮吸收效率分别提高136.16％和65.43％,紫茄产量提高46.85％和28.49％,水分利用效率提高44.59％和27.38％;粉黏质壤土AI和HP处理作物氮素吸收效率分别提高141.23％和88.76％,产量分别提高41.52％和20.68％,水分利用效率提高41.06％和21.39％;砂壤土AI和HP处理作物氮素吸收效率分别提高112.60％和45.47％,产量提高49.86％和17.59％,水分利用效率提高48.81％和17.97％.[结论]曝气地下滴灌对紫茄生长、水分和养分利用的促进作用较为显著,而在不同土壤类型下,曝气地下滴灌对砂壤土紫茄产量增产及水分利用效率提升效果最优.
