摘　　要：以芹菜为试材,研究盆栽条件下咸水(NaCl溶液60mmol/L)与淡水交替灌溉对芹菜生长、生理生化特性及品质的影响。结果表明:只浇咸水可显著抑制芹菜株高生长,其抗氧化酶活性、叶绿素含量及可溶性糖含量显著升高;随着淡水灌溉次数的增加,可降低NaCl对芹菜生长、生理生化特性及品质的抑制作用;其中,1∶2咸淡水交替灌溉处理的芹菜叶片数、干鲜重、MDA及叶绿素含量、维生素C及膳食纤维含量相对于淡水处理差异均不显著,未对芹菜产生显著盐胁迫,说明1∶2咸淡水交替灌溉是较适宜的咸淡水交替灌溉方式。With celery as material,a pot experiment was conducted, the effect of alternative irrigation with NaC1 solution （60 mmol/L） and fresh water on the growth, physiological and biochemical characteristics and quality of celery were studied. The results showed that, irrigation with only saline could significantly reduce the celery plant height, increase SOD activity,CAT activity, chlorophyll content and soluble sugar content. With the increasing of fresh water irrigation times,the inhibition of NaCl on the growth of celery reduced, under 1 ： 2 treatment,leaf number,fresh and dry weight, MDA content, chlorophyll content, vitamin C content and fiber content were no significant differences relative to CK, it showed 1 ： 2 treatment was more appropriate alternative irrigation method under 60 mmol/L of NaCl solution.
