Abstract The investigation on the nutrient solution management of tomato cultivation under modern greenhouse showed that ranges of pH in nutrient solution and drainage solution were 5.0-6.0 and 6.0-7.0 respectively. The EC value in drainage solution was 1.0ms·cm -1 higher than that in nutrient solution. The important factors affecting the amount of nutrient solution supply were light intensity and temperature. The amount of drainage was over 40% of irrigation amount. Tomato needed more N,Ca and Mg during vegeta...
