Application of Biomass Fertilizer Synergist in Tobacco Production

A field test was conducted to study application offect of biomass fertilizer synergist in tobacco.The results showed that there was no difference in growth period,agronomic characters,yield,output value and average price among the treatments with 15% biomass fertilizer synergist,30% biomass fertilizer synergist and CK,but they were significantly different with the treatments with 45% biomass fertilizer synergist and 60% biomass fertilizer synergist.The first-class tobacco ratio of the treatment with 45% biomass fertilizer synergist was the maximum(43.4%) among all treatments but the first and second class tobacco ratio of the treatment with 30% biomass fertilizer synergist was up to 95.6%,which indicated that the fertilizing technique of 30% biomass fertilizer synergist cowld be used in tobacco production.
