Abstract:

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.

Key words: coastal saline-alkali land, rotation irrigation of brackish and fresh water, greenhouse tomato, yield, quality
