为提高烟叶质量,探索不同微量元素配合施用对烟叶产量和品质的影响。结果表明:在Mg、B有效含量偏低的土壤上,施用Mg、B肥能够明显改善烟草的农艺性状,提高烟叶的产量、品质和产值。在供试条件下,Mg、B配施效果最佳,施用Mg10kg/667m2和喷施稀释1000倍的“好迪B”B液90L(分3次),烟草产量为2743.35kg/hm2,产值增加42303.6元/hm2,上中等烟88.2% In order to improve the quality of tobacco leaves, the effects of different trace elements on the yield and quality of tobacco were explored. The results showed that Mg and B fertilizers could significantly improve the agronomic characters of tobacco and increase the yield, quality and output value of tobacco leaves in soils with low Mg and B effective contents. Under the conditions of the test, Mg and B were the best. The yield of tobacco was 2743.35kg / hm2 by applying Mg10kg / 667m2 and sprayed with 1000 times “Hedy B” B solution 90L Output value increased 42,303.6 yuan / hm2, upper middle-class smoke 88.2%
