改善烤烟化学组分综合措施效应研究

Study on the Effects of the Comprehensive Measures to Improvement of the Chemical Element of Flue-cured Tobacco

本文探讨了遗传效应、营养效应以及综合栽培措施对烤烟产量和质量的影响,结果说明,1)在同等条件下,不同烤烟品种间主要化学组分含量和协调性存在显著差异,K326品种综合指标理想,其次是Nc89、K394。长脖黄品种不能生产优质烟叶。2)施肥水平,亩施纯氮4.0～5.0kg,纯磷(以P_2O_5计)9.0～10.0kg,N:P:K 是1:2～2.5:3时最适宜。3)提出了实现烤烟优质、丰产、高效益的最佳方案。

This research experiment deals with the effects of the comprehe nsive measures to the improvement of flue-oured tobacco chemical componen- ts. 1)Hereditary effects works the basis of fine quality tobacco leaves. Great varieties exist in the principal chemical components as well as the possibility of coordination between different breeds of flue-cured tobacco.The general index of K326 shows the best followed by Nc89,K394. 2)Re- quiring pure Nitrogen 4.0～5.0kg per mu,pure phosphorus(P_O_5)9.0～10.0 kg,N:P:K=1:2～2.5:3. 3)this thesis provdes the best scheme to the realization of highest quality,bumper-crops and high economic efficiency of flue-cured tobacco.
