摘要: 为协调烟株营养平衡,优化烟草专用肥配方,将硫酸锌0、6、12 kg/hm2和硫酸镁0、30、60 kg/hm2及钼酸铵0、90、180 g/hm2按L9(34)方式,运用SPSS 17.0 正交试验设计生成施肥处理表,通过田间试验,研究配施锌、镁、钼肥对烤烟钾、氯含量影响的主次因素,肥料施用量对烤烟钾、氯含量的影响及主体间的效应。结果表明:硫酸锌的施用对烤烟钾含量的影响高于硫酸镁、钼酸铵,就烤烟钾含量而言最佳的配施方案为硫酸锌6 kg/hm2、钼酸铵0 g/hm2、硫酸镁60 kg/hm2;烤烟氯含量受钼酸铵施用的影响高于硫酸锌、硫酸镁。

Abstract: To coordinate the nutrition of tobacco plant and optimize the formula of tobacco special fertilizer,In this paper, according to L9(34) method,zinc sulfate (0, 6, 12 kg/hm2 )、 magnesium sulfate( 0, 30, 60 kg/hm2 )and Mo fertilizer (0, 90, 180 g/hm2) are designed to produce fertilizer treatment table by using SPSS17.0 ,through field experiment,the primary and secondary factors of zinc、 magnesium and Molybdenum Fertilizer on the content of potassium and chlorine in flue-cured tobacco was studied,also the effect of fertilizer application rates on potassium and chlorine content in Flue-cured Tobacco and its inter subjectivity effect analysis.The results show:The effect of zinc sulfate on potassium content of flue-cured tobacco was higher than that of magnesium sulfate and molybdenum fertilizer,in terms of the potassium content of flue-cured tobacco, the best matching scheme was zinc sulfate (6 kg/hm2)、Molybdenum fertilizer(0g/hm2 )and Magnesium sulfate (60kg/hm2) ,and the effect of Molybdenum fertilizer on chlorine content of flue-cured tobacco was higher than that of zinc sulfate and magnesium sulfate.
