摘要
为了缓解重茬烤烟养分吸收情况,以烤烟品种龙江911为材料,通过田间试验的方式研究不施肥、施用烤烟专用肥和腐植酸复混肥对烤烟氮积累与烤烟产量的影响。结果表明:根系氮积累量在17周时B3(腐植酸肥与烤烟专用肥混施)处理处于最高值,与B2(烤烟专用肥)处理相比提高45.42%,差异显著;茎内氮积累成熟期B3比B2处理提高32.82%,差异显著;下部叶成熟期B3比B2处理提高27.95%,差异显著;中部叶B3比B2处理提高9.34%,差异不显著;上部叶B3比B2处理提高28.60%,差异显著,B3处理下烤烟的产量和产值最高,显著高于其它处理。综合分析认为,施用腐植酸复混肥对提高烤烟氮积累量和产量效果最佳。
In order to alleviate the problem of nutrient uptake of continuous cropping flue-cured tobacco,taking Longjiang 911 as material,the effect of treatments of no fertilization,flue-cured tobacco specific fertilizer and humic acid compound fertilizer on flue-cured tobacco nitrogen accumulation and yield were studied by the way of field experiment. The results showed that root nitrogen accumulation in B3 （humic acid compound fertilizer） was on peak at 17 weeks, compared with B2 （flue cured tobacco specific fertilizer）it increased by 45. 42%, which was significant difference with B2;Nitrogen accumulation in stems of B3 increased 32. 82% than B2, which was significant difference with B2;B3 increased 27.95% than B2 of bottom leaves in maturity, which was significant difference with B2;B3 increased 9.34% than B2 in middle leaves,which was not significant differ- ence with B2% B3 increased by 28.60% than B2 in upper leaves,which was significant difference with B2. The yield of B3 treatment was the highest, which significantly higher than others,and the productionvalue was also significantly higher than others. Applying humic acid compound fertilizer had the best effect for improve the nitrogen accumulation and yield of flue-cured tobacco.
