抗水解稳定离子钛对烤烟生长发育和品质的影响

目的]研究抗水解稳定离子钛对烤烟生长发育和品质的影响,为优质烟叶生产技术提供理论依据。方法]在不同时期采用不同方式对烤烟施用抗水解稳定离子钛,研究烤烟田间生长状况、常规化学成分和致香物质含量的变化。结果]施用抗水解稳定离子钛可以显著促进烤烟的生长发育,处理T7移栽时喷施叶面肥(1∶1 000)+移栽后30 d喷施叶面肥(1∶1 000)]促进效果最明显。处理T_6移栽时喷施叶面肥(1∶1 000)+移栽后30 d(团棵期)喷施叶面肥(1∶600)]的总糖、还原糖和总氮含量均接近优质烟叶的要求,降低上部叶和中部叶的烟碱含量,提高烤烟中部叶钾含量。处理T_5移栽时喷施叶面肥(1∶1 000)+移栽后30 d(团棵期)喷施叶面肥(1∶200)]的总糖、还原糖含量也较适宜,同时处理T_5可以显著增加上部叶钾含量,提高烟叶可用性。处理T_7总糖和还原糖含量偏高,不利于烤烟烘烤质量的体现。结论]总体来看,处理T_6效果最好,T5次之。

Effects of Hydrolytic Stability Titanium Ion on Growth and Quality of Flue-cured Tobacco

Objective] To study effects of hydrolytic stability titanium ion on growth and quality of flue-cured tobacco,and provide the theoretical basis for production technology of quality tobacco.Method] Hydrolysis stability titanium ion was applied in different ways in different periods of the flue-cured tobacco,and changes of growth,routine chemical components and aroma substance content of the flue-cured tobacco were studied.Result]Application of hydrolytic stability titanium ion could significantly promote the growth of flue-cured tobacco,T7transplanting spraying the leaf fertilizer (1:1000) + 30 d after transplanting spraying the leaf fertilizer (1:1 000)] was the best.Total sugar,reducing sugar and total nitrogen of T6transplanting spraying the leaf fertilizer (1:1000) + 30 d after transplanting spraying the leaf fertilizer (1:600)] were close to the requirements of high-quality tobacco leaf,reduced nicotine content of upper leaves and central leaves,increased potassium content of central leaf.Total sugar,reducing sugar content of T5transplanting spraying the leaf fertilizer (1:1 000) + 30 d after transplanting spraying the leaf fertilizer (1:200)]was more appropriate,and T5 had a significant increase in potassium content of upper leaves,improve the availability of tobacco.The content of total sugar and reducing sugar content of T7 was high,which was unfavorable for reflecting the quality of flue-cured tobacco curing.Conclusion]Overall,T6 was the best,T5 was second.
