锰肥及锰、锌、硼肥配施对烤烟K326生长和产质量的影响

[目的]在大田条件下,研究锰肥及锰、锌、硼肥配施对烤烟生长和产质量的影响。[方法]设置3个处理,分别为T1、T2、T3。T1为对照,不施用微肥。在对处理T2、T3进行微肥处理时,T1处理施用等量清水;T2为施用锰肥;T3为同时施用锰、锌、硼肥。[结果]锰肥及锰锌硼肥配施对烤烟K326农艺性状没有显著差异;锰肥及锰、锌、硼肥配施可以增加烟叶产量、产值,提高中上等烟比例,单施锰肥(T2)及锰、锌、硼肥配施(T3)的产量分别比对照增加了0.48%、17.46%,产值分别增加了28%、30%,而单施锰肥的处理中上等烟比例比T3增加了11个百分点。单施锰肥及锰、锌、硼肥配施的处理化学品质较对照有所改善。[结论]单施锰肥及锰锌硼配施都有利于优质烟叶生产。

Effect of Spraying Manganese Fertilizer and Manganese-Zinc-Boric Mixed Fertilizer on Yield and Quality of Flue-cured Tobacco

[ Objective] The research aimed to study the effects of spraying manganese fertilizer and the manganese-zinc-boric mixed fertilizer on yield and quality of flue-cured tobacco. [ Methodl There were three treatments in the experiment such as T1, T2, T3. T1 was treated as control, which wasn＇t applied with fertilizer,but treated with the same quantity water as the other two treatments applied with micro-fertilizer. T2 was ap- plied with manganese fertilizer, and lhe T3 was treated with manganese fertilizer, zinc fertilizer, and boric fertilizer at the same time. [ Result] Applying manganese fertilizer （T2） , and applying the mixture of manganese-zinc-boric （T3） could increase the yield. The yield value and the quality of flue-cured tobacco were improved. In T2, the yield was increased by 0.48% , and the yield value was increased by 28%. In T3, it was the most obvious that the yield was increased by 17.46%, and the yield value was increased by 30%. The total nitrogen, phosphorus, potas- sium, protein and sugar alkali were in a suitable area in both T2 and T3. [ Conclusion ] Applying manganese fertilizer with the zinc （T2）, and applying the mixture of manganese, zinc, and boric （T3） were both good for getting higher quality tobacco leaves.
