Abstract: In order to investigate the effects of medium and trace element fertilizers on the quality improvement, yield increase and disease resistance of tomato, a conventional fertilizer treatment and a Stoller medium and trace element fertilizer treatment were set to compare the biological and economic traits of tomato. The results showed that compared to the conventional fertilizer treatment, the plant height increased by 14.30% and node spacing increased by 17.02%, both of which reached highly significant differences by the Stoller fertilizer treatment. In addition, chlorophyll content, stem thickness and leaf thickness increased by 4.05%, 3.80% and 2.16%, respectively. Furthermore, the Stoller fertilizer treatment increased production by 568.09 kg, which higher than the conventional treatment by 30.7% per 667 m2. Thus, the experiment showed that Stoller medium and trace element fertilizer could promote tomatoes' growth and yield, which could be further expanded. |
