The field application effect of tobacco yield, quality and physical and chemical properties of soil conditioners in the alluvial sandy soil in Meizhou tobacco area was studied. Both conditioner I and conditioner II significantly increased yield, output value, ratio of high quality tobacco and average price. The yield and output value of conditioner I was 30.42% and 57.56% higher than that of the control, and conditioner I significantly reduced the incidence of tobacco bacterial wilt and tobacco mosaic virus. Conditioner I increased soil pH by 1.42 compared with the control, and the content of available potassium, exchangeable magnesium and exchangeable calcium in conditioner I treatment was 13.21%, 63.21% and 4.9 times higher than that of the control. Both conditioners increased the number of bacteria and actinomycetes in the soil. Conditioner I significantly increased the activity of soil invertase, phosphatase, urease and dehydrogenase.

Key words: soil conditioner, flue-cured tobacco, alluvial sandy soil, physical and chemical properties, yield and quality
