Abstract:
Taking two tomato varieties,‘Provence’ and ‘Galina’,as experimental materials,the effects of different substrate cultivations (coconut coir,sand,mixed substrate) on the growth,leaf SPAD value,photosynthetic characteristics,fruit quality,and yield of greenhouse tomatoes (‘Provence’ and ‘Galina’) were studied by using soilless cultivation methods,in order to provide reference for tomato growth and development quality in Hotan,Xinjiang.The results showed that under the Gobi desert solar greenhouse conditions in Xinjiang,the plant height and SPAD values of ‘Provence’ tomatoes were consistently higher than those of the ‘Galina’ across all three substrate treatments.Different substrate treatments significantly influenced the photosynthetic characteristics,fruit quality,and yield of tomatoes.Specifically,the S3 treatment (mixed substrate) achieved the highest net photosynthetic rate and transpiration rate,with significant increases of 10.52%,20.15%,31.17% in net photosynthetic rate and 6.67%,5.87%,7.52% in transpiration rate compared to the N1,N,and N3 treatments,respectively.Additionally,the S3 treatment significantly enhanced the levels of vitamin C,soluble solids,total sugars,and total acids in the fruit compared to the N1,N2,and N3 treatments.The highest yield per 667 m2 was also observed in the S3 treatment.In summary,the mixed substrate treatment outperformed the coconut coir and sand substrates in terms of plant growth,yield,and fruit quality.Among the tested combinations,the ‘Provence’ grown in the mixed substrate exhibited the best overall performance.
