Abstract:
Taking tomato variety of ‘Hexie’ as material,the effect of ventilation volume (the vents opening were 100%，75%，50%) and shading rate (shading rate were 0，50%，75%) on plastic greenhouse environment and tomato plant growth were studied in Qingdao summer high temperature period.In order to screen the adjusting technology of tomato over-summer cultivation based on temperature and light environment，tomato plant growth，yield and quality.The results showed that under the same lighting conditions，temperature gradually decreased，and the single fruit weight and total yield of tomato increased with the increasing of ventilation rate in plastic greenhouse.There were not significant influence in quality of tomato fruit among ventilation treatments.Under the same ventilation conditions，tomato quality increased with the decreasing of shading rate in plastic greenhouse.While appropriate shading was more conductive to the formation of tomato total yield.In Qingdao area，covering with a layer of shading net and all vents opening treatment (shading rate 50%，opening vent 100%) was the best temperature and light environmental regulation technology of tomato over-summer cultivation in plastic greenhouse.
