摘要: 为提高烟叶品质,在河南省洛宁县、泌阳县进行多点对比试验,研究不同调节剂(壳寡糖、低聚木糖、磷酸二氢钾、硝酸钾、黄腐酸钾)对烟叶钾含量的影响。结果表明,与常规对照相比,除洛宁县试验点处理T6(黄腐酸钾)外,其他调节剂处理均能促进烟叶叶片发育,提高叶面积。2个试验点调节剂处理与常规对照相比,产量有一定提高,但差异不显著,洛宁县和泌阳县试验烟叶产值分别提高2.4%~20.2%和6.6%~20.6%,均价和上等烟比例均以处理T4(磷酸二氢钾)最高。与常规对照相比,施用调节剂处理中部烟叶钾含量均有增加,2个试验点均以处理T4中部叶钾含量最高,调节剂处理均降低了烟碱含量和氯离子含量,2个试验点均以处理T3(低聚木糖)烤后烟叶钾含量最高,分别为1.99%和2.15%。叶面喷施调节剂能够提高烟叶叶面积、产量产值和品质,不同调节剂处理间比较,以处理T3和处理T4表现较好。

Abstract: In order to improve tobacco quality, the comparative test was conducted in Luoning county and Biyang county of Henan province to study the effects of foliar spraying of different regulators (chitosan oligosaccharide, xylo-oligosaccharide, potassium dihydrogen phosphate, potassium nitrate, fulvic acid potassium salt) on quality of tobacco leaves. The results showed that, compared with CK, except treatment T6(fulvic acid potassium salt) in Luoning county, foliar spraying of different regulators promoted leaf development and increased leaf area. Compared with CK in both testing points, foliar spraying of different regulators increased the yield but the differences were not significant. The output value of Luoning county and Biyang county increased by 2.4%~20.2% and 6.6%~20.6%,respectively. The average price and high grade leaf proportion of treatment T4(potassium dihydrogen phosphate) were highest in the two testing points. Compared with CK, the potassium content of middle leaves with regulator application were increased and the potassium content of treatment T4 were highest in the two testing points. The nicotine and chlorine content of regulator application treatments decreased while the potassium content increased. The potassium content of cured leaves with treatment T3(xylo-oligosaccharides) were highest in the two testing points and the potassium content were 1.99% and 2.15%, respectively. Foliar spraying of different regulators could increase leaf area, yield, output value and quality of tobacco leaves. Among different treatments, treatment T3 and treatment T4 were better.
