Abstract：This experiment was treated with 5 kinds of different proportion of organic fertilizer in the tobacco plants ,and the microorganism of 20 d ,40 d ,60 d ,120 d rhizosphere soil were tested respectively before and after the transplanting in order to study the effect of different organic fertilizer on tobacco rhizo-sphere microorganisms .The experimental results showed that :with the increase of the proportion of organ-ic manure ,the amount of fungi ,bacteria and mould in tobacco rhizosphere were higher than the treatment without the addition of organic manure(N0 treatment);among them ,the treatment of 50% inorganic nitro-gen +50% organic nitrogen (N3 treatment )could significantly increase the number of microorganisms in the rhizosphere soil of tobacco ,and the quantities of fungi ,bacteria and mould were 2 .46 × 105 cfu/g ,2 .96 × 108 cfu/g ,2 .95 × 104 cfu/g respectively .The experimental results also revealed that the application of Organic fertilizer including 50% inorganic nitrogen and 50% organic nitrogen was conducive to improving the quantity of microorganisms in tobacco rhizosphere .
