Abstract The experiment was conducted in solar greenhouse with tomato varieties Zhongza No.9 and Beril, in order to investigate the nutrient absorption characteristics in winter-spring. The results showed that, except P 2O 5, the uptake rate and amount of total N, K 2O, Ca, Mg, and Fe of Beril is obviously higher than that of Zhongza No.9. The uptake percentage of main elements is also different between varieties. Zhongza No.9 has a higher percentage of P 2O 5 and K 2O, but has a lower percentage of Ca and Mg.
