Abstract:

Taking lettuce as the material,the relationship between nitrogen application and the lettuce quality and yield were analyzed by the district experiments and chemical assay.The results showed that the content of soluble sugar,content of vitamin C and yield increased and then decreased，the Nitrate content increased with the nitrogen application.The best nitrogen application of lettuce was 20 g/m².
