Abstract:

To determine the optimal water\|nitrogen\|salt coupling model for processing tomatoes under drip irrigation in the northern Xinjiang region, the ‘Jinfan 3166’ processing tomato variety was used as the research subject. The experimental design included three irrigation levels: 5 200 (W1)， 4 500 (W2)， and 3 800 (W3) m³·hm^-2； three nitrogen application levels: 300 (N1)， 240 (N2)， and 180 (N3) kg·hm^-2；and three salinity levels: 1 (S1)， 3 (S2)， and 5 (S3) g·L^-1. An L9 (3³) orthogonal experimental design was used to investigate the effects of different water\|nitrogen\|salt treatments on the yield, irrigation water use efficiency, and nitrogen fertilizer partial productivity of processing tomatoes, and to develop a multi\|objective optimization model. The results indicated that increasing irrigation and nitrogen application, while reducing irrigation water salinity, significantly improved both the yield and irrigation water use efficiency of processing tomatoes. Conversely, increasing the irrigation amount and salinity, while reducing nitrogen application, notably enhanced the partial productivity of nitrogen fertilizer. The W1N1S1 treatment achieved the highest yield and irrigation water use efficiency, reaching 188 t·hm^-2 and 36.15 kg·m^-3， respectively， while the W1N3S3 treatment resulted in the highest nitrogen fertilizer partial productivity， at 760.50 kg·kg^-1. Comprehensive evaluation using the entropy weight TOPSIS method indicated that the W1N1S1 treatment had the highest overall evaluation index (0.859) ，making it the optimal treatment. Based on the combination of the multi\|objective genetic algorithm and entropy weight TOPSIS evaluation method， the optimal solutions for water (W) and nitrogen (N) regulation under different salinity levels (S) were derived as follows： When S=1 g·L^-1，W=5 200 m³·hm^-2，N=300 kg·hm^-2， the optimal values for yield (Y₁)， irrigation water use efficiency (Y₂)， and nitrogen fertilizer partial productivity (Y₃) were 189.88 t·hm^-2， 36.07 kg·m^-3， and 593.44 kg·kg^-1， respectively； when S=3 g·L^-1，W=5 200 m³·hm^-2，N=180 kg·hm^-2，Y₁=129.06 t·hm^-2，Y₂=17.75 kg·m^-3， and Y₃=679.04 kg·kg^-1；when S=5 g·L^-1，W=3,800 m³·hm^-2，and N=180 kg·hm^-2，Y₁=134.06 t·hm^-2，Y₂=24.87 kg·m^-3， and Y₃=582.25 kg·kg^-1.
