Abstract:

The experiment was studied the changes of N nutrient in tomato that was planted in substrates mixed by different ratio, including peat, vermiculite, perlite and sand. The results showed that the N contents of tomato absorbed from the different treatments were obviously discrepancy. From the overall level, the substrate of C treatmeat was conducive to the absorption of tomato, and C treatment was superior to other treatments. In different periods, the N contents were different change trends of tomato leaves and fruit, and the N content in leaves was higher than the fruit. The N content of tomato was decreasing with prolonging growth period.
