Abstract：
Temperature and light are the key factors affecting the formation of tomato fruit quality in greenhouse cultivation. However, there are few simulation models that examine the relationship between tomato fruit quality formation and temperature and light. In this study, a model was established that investigated the relationships between soluble sugar (SSC), organic acid content (OAC), and SSC/OAC and the cumulative product of thermal effectiveness and photosynthetically active radiation (TEP) during the fruit-ripening period in a solar greenhouse. The root mean square error (RMSE) values were calculated to compare the consistency between the simulated and measured values, and the RMSE values for SSC, OAC, and SSC/OAC were 0.09%, 0.14%, and 0.358, respectively. The combined weights of quality indicators were obtained using the analytic hierarchy process (AHP) and entropy weighting method, ranking as SSC > OAC > SSC/OAC > CI > lycopene > Vc > fruit firmness. The comprehensive fruit quality evaluation value was obtained using the TOPSIS method (Technique for Order Preference by Similarity to an Ideal Solution) and a simulation model between comprehensive tomato fruit quality and TEP was explored. This study could accurately simulate and quantify the accumulation of tomato fruit quality during fruit ripening in response to environmental conditions in a solar greenhouse.
摘要：
温度和光照是影响温室栽培番茄果实品质形成的关键因素。然而,很少有模拟模型来检验番茄果实品质形成与温度和光照之间的关系。在这项研究中,建立了一个模型，研究了可溶性糖(SSC)、有机酸含量（OAC），和SSC/OAC以及日光温室果实成熟期的热效率和光合有效辐射（TEP）的累积乘积。计算均方根误差(RMSE)值,比较模拟值与实测值的一致性,和SSC的RMSE值，OAC,SSC/OAC为0.09%，0.14%，和0.358。采用层次分析法(AHP)和熵权法得到质量指标的组合权重,排序为SSC>OAC>SSC/OAC>CI>番茄红素>Vc>果实硬度。使用TOPSIS方法（与理想解决方案相似的顺序偏好技术）获得了综合果实品质评估值，并探索了番茄果实综合品质与TEP之间的模拟模型。该研究可以准确地模拟和量化日光温室中番茄果实成熟过程中果实品质的积累，以响应环境条件。
