| In EM210 solar greenhouse,the Galilieo—LPS plant physiological monitor system and the greenhouse meteorological observation system were adopted to monitor continuously the real-time weather factors and the eco-physiological characteristic values in tomato.The results indicated: the growth features of different size of tomato fruits were much different;the increasing course of small tomatoes showed "ladder" model,and that of big and middle ones showed "wave" model.The daily change of leafstalk stem-flow velocity presented "double-apex" model.When the air temperature was 1.7℃ higher than the leaf temperature,the growth of tomato was harmed by high-temperature,and "the noon break of stem-flow velocity" phenomenon was found during 12 to 16 o'clock.In tomato production under solar greenhouse,it is necessary to startup the temperature regulation equipment in time when the temperature is beyond 30.5℃. |
