摘要: 通过大田间小区试验,在贵州省仁怀市针对烤烟双行凹垄全生育期地膜覆盖开展免追肥条件下的不同肥料配方田间效果对比研究。结果表明,从烤烟的经济指标、内在质量和化肥减施综合考虑,N施用量为91.20 kg/hm2且N、P2O5、K2O配比为1.0∶0.7∶2.4综合表现最好,与传统的单行地膜覆盖且两次追肥相比,烟叶产值增加11.0%,均价增加2.3元/kg,总糖、还原糖含量分别增加19.9%和16.9%,烟碱含量下降14.6%,化肥用量减少9.9%。

Abstract: The field plot experiments were carried out to study the effects of fertilizer formulations on the yield and quality of flue-cured tobacco under the condition of double-row concave ridge and free topdressing in Renhuai city, Guizhou province. The results showed that, the best economic indicators, internal quality and fertilizer reduction of the tobacco leaves were obtained by the treatment of N application rate 91.20 kg/hm2 and the ratio of N, P2O5 and K2O with 1.0∶0.7∶2.4. Compared with traditional single plastic mulching and two topdressing, production value of tobacco leaves of double-row concave ridge and free topdressing treatment increased by 11.0%, the average price increased by RMB 2.3 yuan/kg, and the total sugar, reducing sugar content increased by 19.9% and 16.9% respectively, furthermore, the nicotine levels and fertilizer rate fell by 14.6% and 9.9%.
