Abstract: With ‘NC102’ as the test material, different dosages (CK、T0、T750、T1125、T1500) of silicon calcium potassium magnesium fertilizer gradient treatment were set up under the condition of the field to determine the indexes with the methods of systematic sampling, which invested the effect of the new soil conditioner on soil nutrient and leaf quality in tobacco field and explored the role of silicon calcium potassium fertilizer in the improvement of acidified soil, hoping to repair the soil environment, improve the tobacco growth and tobacco quality, and guide the quality production management of tobacco. Experimental results showed that T1125 (i.e., silicon calcium potassium magnesium fertilizer 1125 kg/hm2) g6t the best treatment effect, the soil pH of which increased by 0.3 units, the potassium content of leaves increased by 0.3 percentage points, the output value increased by 4091.7 Yuan per hectare, the average price increased by 1.5 Yuan/kg, and the proportion of fine tobacco increased by 3.0 percentage points.
