Abstract：Taking tobacco cultivar NC55 as material, the effects of combined application of soybean cake fertilizer and inorganic fertilizer on inorganic nitrogen supplication and related enzyme activity in tobacco plant -ing soil were studied .The results indicated that the soil inorganic nitrogen content reached the maximum at 50 th day after tobacco transplanted , and the treatment of 30%soybean cake and 70%inorganic fertilizer had higher content than the others .The soil sucrase , urease and nitrate reductase activity of the treatment of only inorganic fertilizer were always below than other treatments .Combined application of 70% soybean cake and 30%inorganic fertilizer had higher sucrase , urease and nitratase activity than the others in the tobacco grow-ing critical period .
