Abstract:

In order to explore the optimal substrate cultivation methods for the production of cherry tomatoes in winter facilities within the Yangtze River Delta region, this study compared the effects of coconut coir bag cultivation and mixed substrate (peat and perlite mixed at the volume ratio of 2∶1) groove cultivation on tomato plant growth, fruit yield, and quality related indicators using three types of cherry tomatoes as materials. The results showed that the maximum leaf length, maximum leaf width and stem diameter of tomato plants cultured in the mixed substrate groove were significantly (p<0.05) higher than those cultivated in coconut coir bag. The single fruit weight and early yield per plant of tomatoes cultured in mixed substrate groove were increased by 27.9% to 44.8% and 26.1% to 44.6%, respectively, compared with those cultivated in coconut coir bag. In terms of fruit quality, sugar content and vitamin C content of tomato fruits cultivated in the mixed substrate groove were increased by 0.50 to 1.30 percentage points and 13.0% to 37.9%, respectively, compared with those cultivated in coconut coir bag. There were no significant differences in fruit number in the first three ears, sugar-acid ratio, lutein content and lycopene content between tomatoes cultivated in two substrate cultivation methods. In conclusion, mixed substrate groove cultivation is more suitable for the production of cherry tomatoes in winter facilities in the Yangtze River Delta region.
