Abstract: The experiment was conducted in solar greenhouse using Zhongza9 tomato variety in order to investigate the light and temperature in greenhouse, and the distribution of nitrogen, phosphorus and potassium in soil culture in winter-spring and autumn-winter crops. The results showed that the distribution of total N, P2O5 and K2O was influenced by light and temperature condition in greenhouse. Both in winter-spring and autumn-winter crops, the distribution trend of total N, P2O5 and K2O was the same as dry material, i.e. before fruit formation stage, mainly distributed in the stem and leaves, in fruit formation stage, mainly distributed in the fruit. In autumn-winter crop, because of the abominable light and temperature condition, the distributing proportion of N, P2O5 and K2O in early stage of picking and middle stage of picking was higher than that in winter-spring crop. The concrete proportion changed with different elements and growth stages.
