摘　　要：为研究腐殖酸对克服烤烟重茬障碍的效果,试验在田间试验条件下设置对照(B1),当地常规施肥(B2),腐殖酸复混肥(B3)3个处理,研究了烤烟氮积累与烟叶品质变化规律。结果表明:根系氮积累生育期内呈现出增加的趋势,收获期B3处于最高值,与B2相比提高32.62%;茎内氮积累成熟期B3比B2处理提高41.62%,差异显著;下部叶成熟期B3比B2处理提高35.37%;中部叶B3比B2处理提高14.61%,差异显著;上部叶B3比B2处理提高32.64%,差异显著;B3促进氮在茎内的分配,比B1和B2处理分别提高5.27%、1.84%;B3产量与产值分别比B2提高6.94%、7.94%,烟叶质量评分下部叶、中部叶、上部叶分别低于B2处理1.50分、2.00分、2.00分。综合分析认为,腐殖酸对提高烤烟氮积累量和产量效果最佳。In order to study the effects of humic acid in overcoming cropping obstacles of flue-cured tobacco ,three trials in the field were set including control （B1 ） ,local conventional fertilization （B2 ） ,and humic acid fertilizer （B3 ） , to investigate the changes of nitrogen accumulation and quality in flue-cured tobacco .The results showed that root nitro-gen accumulation tended to be increased during reproduction ,reaching the highest level with B3 treatment ,32 .62%higher than that by B2 during harvest .Stem nitrogen accumulation with B3 treatment was 41 .62% higher than that with B2 ,exhibiting significant differences .Nitrogen accumulation in lower leaves with B3 treatment was 35 .37% higher than that with B2 treatment .Middle leaves with B3 were 14 .61% higher than those with B2 treatment ,displaying significant differences .Upper leaves with B3 were 32 .64% higher than those with B2 treatment ,showing significant differences . B3 treatment promoted distribution of nitrogen into stem ,5 .27% and 1 .84% higher than B1 and B2 treatments ,respec-tively .Yield with B3 was 6 .94% and 7 .94% higher than B1 and B2 ,respectively .Leaf qualities of lower ,middle , and upper leaves scored 1 .50 ,2 .00 ,and 2 .00 lower than those with B2 treatment .Comprehensive analysis indicated that humic acid played important roles in improving nitrogen accumulation ,resulting in best yield of flue-cured tobacco .
