中微量元素对雪茄烟叶的施用效果

为了探究不同中微量元素在雪茄烟上的施用效果，本研究采用田间试验的方法，对比了增施不同中微量元素肥料对雪茄烟烟叶产量、产值、等级结构及表观品质的影响。中微量元素施用能够提高烟叶总产量，其中施用锌肥总产量提升最高可达1716kg/hm2。施用Ca、Mg、Zn和B通过提高中上部烟叶茄衣、茄套产量，改善烟叶等级结构，从而提高产值。施用B处理茄衣产量和烟叶产值均最高，分别可达到21.36%和16.7万元/hm2。施用中微量元素能调节叶表观质量以及烟叶化学协调性，但并无显著性提升。因此，在丹江口烟区增施中微量元素有利于雪茄烟生长，其中增施适宜B肥有利于烟叶产量、茄衣产量及经济价值的提升。

The Effect of Medium Trace Elements on The Administration of Cigar

In order to explore the application effect of different medium and trace elements on cigars, this study adopted the method of field experiment to compare the effects of the different medium and trace element fertilizers on the yield, output value, grade structure and apparent quality of cigar leaves. The application of medium and trace elements can increase the yield of leaves, and the total yield can be increased by up to 1716 kg/hm2 by zinc fertilizer application. The application of Ca, Mg, Zn and B fertilizer can improve the grade structure of cigar leaves and increase the output value by increasing the yield of eggplant coat and eggplant sleeve in middle leaves and upper leaves. The yield of eggplant and the output value of tobacco leaves were the highest on B fertilizer application, reaching 21.36% and 167,000 yuan /hm2 respectively. The application of medium and trace elements can adjust the apparent quality of leaves and the chemical coordination of tobacco leaves, but there is no significant improvement. Therefore, the application of trace elements is beneficial to the growth of cigars in Danjiangkou tobacco-growing areas, and the application of B fertilizer is beneficial to the improvement of the yield of cigar leaves ,the yield of eggplant coat and economic value .
