Abstract:
      To select nutrient solution formula for different tomato variety under coconut bran cultivation,4 kinds of nutrient solution formulas (organic and inorganic mixed nutrient solution 1(F1), organic and inorganic mixed nutrient solution 2(F2), inorganic nutrient solution 1(F3), inorganic nutrient solution 2(F4)) and 4 tomato varieties ‘Feitian’(V1), ‘120-150’(V2), ‘Tongnianwei’(V3),‘DHYZ-03’(V4) were set in glasshouse of Gansu Province in 2020. Bivariate design was coupled to 16 treatments. The stem thickness, photosynthetic characteristics, sugar and yield of different treated tomatoes were studied, and the comprehensive quality of tomato was evaluated by TOPSIS method. The mean soluble sugar content of organic and inorganic mixed nutrient solution was 11.0% and the mean yield was 190 380 kg·hm-2.The mean soluble sugar content of inorganic nutrient solution was 9.6% and the mean yield was 157 969 kg·hm-2.It showed that the organic and inorganic mixed nutrient solution significantly increased the tomato yield and soluble sugar content compared with the inorganic nutrient solution formula. Among the four varieties, the soluble sugar content of ‘Tongnianwei’ was the highest, the mean content was 10.9% the yield of ‘DHYZ-03’ was the highest, and the mean yield was 180 906 kg·hm-2. The highest soluble sugar content sugar treatment was F2V3(organic and inorganic mixed nutrient solution 2+‘Tongnianwei’), the highest yield treatment and the best treatment with both the highest sugar content and yield was F2V2 (organic and inorganic mixed nutrient solution 2+‘120-150’). Under the experimental conditions, F2V3 and F2V2 were more suitable for promotion in Gansu region.
