Effects of different basaldressing application methods and ratio between base and topdressing on yield and quality of fluecured tobacco and reducing nitrogen effect were investigated in field experiment.The results showed that under the condition of rain,digging big holes and supplying 40% basefertilizers at bottom of holes promoted the early nutrient absorption of tobacco plant,to achieve early and quickly growth and improve central leaf quality.Opening degree,leaf area,single leaf weight and tobacco nutrition of upper leaves were improved when the ratio of top dressing increased from 50% to 65%.When the total N application rate reduced by 15% than CK (150 kg·hm-2),optimization of basal fertilization way and the ratio between base and topdressing improved the quality and output value of leaves fluecured tobacco,and increased the economic benefit of tobacco growers.
