面向番茄品质的温室日均温设定点优化及季节差异分析
Optimization of Daily Mean Temperature Setpoints for Tomato Quality and Seasonal Variation Analysis
摘要
Abstract
To address the difficulty of traditional greenhouse temperature setpoint strategies in adapting to seasonal variations while balancing fruit quality and energy use,a Venlo-type glass greenhouse in Tongxiang,Zhejiang Province,was selected as the research site,and a daily mean temperature setpoint optimization method was developed by coupling the Tom-Sugar fruit quality model with a greenhouse energy balance model.Fruit quality was represented by the soluble sugar concentration of mature fruit,while energy use was represented by the deviation between the optimized daily mean temperature and the passive greenhouse daily mean temperature.Simulation analyses were conducted for three typical periods:the relatively warm stage from September to November,the winter low-temperature stage from December to February,and the late warming stage from April to June.The results showed that the average RMSE of indoor temperature simulation across the three periods was 1.08℃.Compared with the empirical strategy,the optimized strategy increased soluble sugar concentration by an average of 22.8%while reducing the overall energy-use indicator by 21.3%.The direction and magnitude of optimal daily mean temperature adjustments varied markedly among seasons.Notably,the winter period achieved the best trade-off,with a 21.1%quality improvement and 65.9%energy reduction under minimal temperature deviation(1.9℃).In conclusion,the optimal temperature trajectories and seasonal adjustment magnitudes obtained herein provide a quantitative refer-ence for quality-oriented temperature management in greenhouse tomato production.关键词
