Thermal Environment Distribution in Mechanized Multi-span Greenhouses and Its Effect on Tomato Growth
摘要
Abstract
An experiment on overwintering tomato cultivation was conducted in a mechanized double-span plastic greenhouse in Cangnan County,Wenzhou,Zhejiang Province.The study aimed to investigate the spatial distribution characteristics of the thermal environment inside the greenhouse and their effects on early crop growth.Air and soil temperature sensors were installed in the southern(area A)and northern(area B)zones to continuously monitor temperature variations at different heights.Temperature data were analyzed alongside crop growth indicators.The main findings were as follows stable north-south temperature gradient was observed.Both air and soil temperatures in area A were significantly higher than those in area B,by 2.1 and 1.1℃,respectively(P<0.05).This difference persisted under both sunny and cloudy conditions,indicating high spatial stability of the thermal environment.The accumulated effective temperature in area A reached 381.8℃·d,which was 102.0℃·d higher than that in area B.The temperature variation between the north and south was primarily influenced by external boundary conditions.The northern side,adjacent to a river,experienced enhanced nighttime heat dissipation and lower soil temperatures.In contrast,the southern side was close to other multi-span greenhouse structures,where heat storage from neighboring buildings slowed the nighttime cooling rate.As a result,a consistent spatial pattern of higher temperatures in the south and lower temperatures in the north was maintained.Differences in the thermal environment significantly affected early tomato growth.Plant height in area A was significantly greater than that in area B at multiple measurement stages,and this growth advantage was closely associated with higher air and soil temperatures as well as higher accumulated effective temperature.In conclusion,this study demonstrates the spatial stability of the thermal environment in a mechanized double-span plastic greenhouse in the Wenzhou area and its influence on tomato growth.The results provide a reference for structural optimization and thermal environment management of similar greenhouses in southern Zhejiang.关键词
