Abstract
The field experiments were carried out to study the effect of combining application of bio organic fertilizer and chemical fertilizer on the soil fertility and the dry matter accumulation of flue cured tobacco. The results showed that adding bio organic fertilizer at the base of using chemical fertilizer can improve the soil fertility, which can increase the content of soil organic and the pH of acid soil. Using bio organic fertilizer made the content of soil rapidly available N,P and K in harmony with the growing of tobacco. It also enhanced the dry matter accumulation of root, stem and leaver of flue cured tobacco.
