Abstract

Effect of different application of nitrogen on yield and quality of tomato and nitrate in soil profile was studied by using the field trial at protective soil of Beijing suburb.The results showed that the recommended application of nitrogen fertilizer compared with the fertilization of farmer′s practice not only increased the yield of tomato,but also increased the quality of tomato;Nitrate content in tomato had an increasing trend with the increasing of nitrogen fertilizer,and the significant differences among the treatments;NO3-N was wave-like change in soil profile,and accumulated in 100 cm soil;NO3-N was highest under the farmer's practice treatment,and was significantly higher than other treatment.
