Abstract:
‘Jinshiwangzi’tomato variety was planted in the soil during spring cultivation season under sheltered cultivation.This paper studied the effect of drip irrigation quantity on leaves photosynthesis and yield of tomato.The results showed that the irrigation quantity had significant effect on photosynthetic parameters，leaf area and yield of tomato.With irrigation quantity increasing，the photosynthetic parameters (photosynthesis rateand transpiration rate) and leaf area increased in the range of 55%-85% soil volumetric water content.However，there was no significant difference in the chlorophyll content of tomato leaves among four experimental treatments.The variational tendency of photosynthesis rate，leaf areas and yield was positive correlation.
