    Variation and simulation of tomato transpiration in a greenhouse under different ventilation modes by Jiankun Ge, Sen Wang, Xuewen Gong, Yuhao Zhu, Zihui Yu, Yanbin Li

    Published 2025-03-01
    “…Meteorological conditions inside the greenhouse and water consumption indicators were analyzed to improve the Penman-Monteith (P-M) model’s resistance parameters (canopy resistance, rc and aerodynamic resistance, ra). Results showed that ventilation significantly influenced water consumption across growth stages, with the highest water consumption intensity observed during the fruit enlargement stage (3.39 mm d−1). rc and ra were significantly lower under T2, with forced convection dominating in both cases. …”
