摘要: [目的] 为研究不同施镁水平对泸州地区烤烟烟叶产量和品质的影响。[方法] 本试验以5个施镁水平(0、50、75、100、125 kg/hm2),3次重复开展大田随机区组试验。[结果] 结果表明:从农艺性状来看,75~125 kg/hm2范围内增施镁肥能明显改善烟株的株高、茎围和节距;从烤烟的产量、产值和上中等烟的比例来看,以50~100 kg/hm2的施镁水平较佳;从烟叶化学品质分析,100~125 kg/hm2范围内增施镁肥有助于提高烟叶的化学品质,各项化学成分含量适宜,比例协调。[结论] 因此,综合考虑建议泸州地区烤烟合理的施镁水平为100 kg/hm2

Abstract: [Objective] The experiment was carried out to study the effects of different magnesium appli-cation levels on yield and quality of flue-cured tobacco in Luzhou City, Sichuan Province. [Method] The field experiment was randomly divided into different small fields, with five levels of magnesium(0, 50, 75, 100, 125 kg/hm) 2. [Results] The results indicated that compared with the other treatments, the plant height, the stem cycle and the pitch of stem were positively improved at the level of Mg 75-125 kg/hm2. There are the highest yield, output value and proportion of superior grade of leaves when magnesium application level was around in 50-100 kg/hm2. When magnesium application level around in 100-125 kg/hm2, the quality of tobacco leaf was improved, and the content of chemical compositions of tobacco leaf were most suitable. [Conclusion] Comprehensively consider the agronomic characters, economic characters and quality, the optimum Mg application level should be 100 kg/hm2 for fluecured tobacco growth in Luzhou City.
