摘　　要：在滨海盐碱地以设施番茄为研究对象,设置4种咸水淡水轮灌次数处理:1:1 (T1)、2:1 (T2)、3:1(T3)、4:1 (T4),以淡水灌溉为对照,探究不同灌溉模式对番茄生长,产量及品质的影响,为盐碱地设施番茄咸水灌溉制度提供数据支撑。结果表明:在咸淡水轮灌处理下,番茄的生物量随着咸水灌溉次数的增加呈先升高再降低的趋势,T1、T2处理下植株生物量积累明显,与对照达到显著水平;随着咸水灌溉次数的增加,T1、T2处理产量及单果重较对照无明显变化,其他处理番茄产量、单果重显著降低;从果实品质分析,各处理均不同程度提高了果实品质。综合分析,T1、T2处理在一定程度上保证了番茄正常生长及产量稳定,并提高了果实品质,是滨海盐碱地区合理有效的咸淡水轮灌模式。In coastal saline-alkali land, the greenhouse tomato was taken as the research object, and four treatments of rotation irrigation of brackish and fresh water were set: 1:1(T1), 2:1(T2), 3:1(T3) and 4:1(T4),with fresh water irrigation as the control. The effects of different irrigation modes on tomato growth, yield and quality were investigated to provide data support for brackish water irrigation system of greenhouse tomato in saline-alkali land. The results showed that: under the brackish and fresh water rotation irrigation treatments,the biomass of tomato increased first and then decreased with the increase of the number of brackish water irrigation times. The biomass of tomato under T1 and T2 was significantly higher than that of the control. With the increase of brackish water irrigation times, the yield and single fruit weight of T1 and T2 did not change significantly compared with those of the control, but the yield and single fruit weight of other treatments decreased significantly;from the analysis of fruit quality, each treatment improved fruit quality to varying degrees. Comprehensive analysis showed that T1 and T2 could ensure the normal growth and stable yield of tomato to a certain extent and improve the fruit quality. Therefore, T1 and T2 are the reasonable and effective rotation irrigation modes of brackish and fresh water in coastal saline-alkali areas.
