摘　　要：通过盆栽试验,研究了3种灌溉方式(机械增氧滴灌、化学增氧滴灌、常规滴灌)对香芹生长特性的影响。结果表明,不同增氧滴灌方式具有不同的增氧效果;与常规滴灌相比,化学增氧滴灌与机械增氧滴灌分别使香芹可食用部分鲜质量平均提升39.84%和15.63%;在化学增氧滴灌的作用下,香芹不同生长阶段叶片叶绿素指数(CCI)、株高以及根茎叶的鲜质量较机械增氧滴灌和常规滴灌均有增加和提高。增氧滴灌促进了香芹植株的整体生长,并增强了香芹植株根茎叶的生理功能,其中化学增氧滴灌方式对香芹相关生长特性影响较为显著。Pot experiment was carried out to study the effects of different aerobic irrigation methods（mechanical aerobic drip irrigation,chemical aerobic drip irrigation and drip irrigation）on growth characteristics of parsley.The results showed that,compared with the drip irrigation,chemical aerobic drip irrigation and mechanical aerobic drip irrigation increased parsley edible part fresh weight by 39.85%and 15.63%on average.The leaf chlorophyll content index（CCI）,plant height and rhizomes leaf weight of parsley in different growth stages were increased and improved by chemical aerobic drip irrigation.Aerobic drip irrigation could promote the overall growth of parsley plants,and enhance the physiological function of parsley plants root leaf.Chemical aerobic drip irrigation had more significant influence on related growth characteristics of parsley.
