Abstract:

To investigate the effects of facility cultivation on agronomic traits and photosynthetic parameters of eight radish varieties in the Huaian region, and to select suitable cultivation methods for improving yield and quality, the comparison experiment of facility cultivation with open-field cultivation were conducted. Measurements of key agronomic traits and photosynthetic parameters showed that under facility conditions, radish fleshy root weight, leaf weight, and fleshy root unearthed length were significantly higher than those under open-field cultivation. Among the varieties, Xinlyu 1439 exhibited the most significant difference in fleshy root weight, with facility cultivation yield 5.45 times greater than open-field cultivation. The net photosynthetic rate of leaves for all eight varieties was higher under facility conditions compared with open-field cultivation, with Xinlyu 1439 showing the most pronounced change, whose net photosynthetic rate reached 5.27 μmol·m-2·s-1 under the facility cultivation, 1.46 times that of open-field cultivation. Comprehensive evaluation of growth performance across cultivation methods revealed that all eight radish varieties grew more robustly under the facility cultivation, displaying superior appearance quality and greater yield potential compared with open-field cultivation.
