Abstract：Taking tomato varieties Qidali and Luomei as materials,the effects of different fertigation fre-quencies of nutrient solution,continuous fertigation,intermittent fertigation for 15 min /15 min and intermittent fertigation for 30 min /30 min,on growth and development,physiological metabolism,yield and quality and water and fertilizer use efficiency of tomato were studied using the closed circulating fluid for elevated pot cul-ture system in solar greenhouse.The results showed that compared with continuous fertigation,the plant growth,photosynthetic rate,root activity of intermittent fertigation for 15 min /15 min and 30 min /30 min sig-nificantly increased.The yield of Qidali increased by 6.33% and 5.53%,and that of Luomei increased by 10.27% and 7.96% respectively.Compared with intermittent fertigation for 15 min /15 min,the contents of soluble sugar,soluble protein and lycopene in treatment of intermittent fertigation for 30 min /30 min signifi-cantly improved.The indicators,plant growth,photosynthetic rate,yield and quality,showed that intermittent fertigation for 30 min /30 min was the optimum frequency for tomato cultured in pod.
