摘　　要：采用双因素随机区组试验,以红壤为对象,研究了不同水平镁、硼肥配施对烟叶镁、硼含量和经济性状的影响。结果表明,对烟叶镁含量的影响主要是镁的独立效应,烟叶硼含量除受硼独立效应的影响外,还与镁有显著的交互作用,镁-硼的交互作用在镁肥水平为180kg/hm^2时效应最大;镁对烤烟产量、产值和中上等烟比例有极显著的影响效应,硼对产值和中上等烟比例有显著的影响效应,镁、硼肥配施对烤烟产值的交互作用有显著的影响效应,其交互作用在硼肥水平为30kg/hm^2时效应最大。在供试条件下,宣威红壤烟区镁、硼肥的最佳用量和施用方法为:180kg/hm^2镁肥配施30kg/hm^2硼肥,其中,50%镁肥和100%硼肥作为基肥塘施,剩余50%镁肥于移栽后30d兑水浇施。A two-factor experiment with randomized block design was carried out to study the effects of combined application of different levels of Magnesium (Mg) and Boron (B) fertilizer on the Mg,B content and economical characters of flue-cured tobacco in red soil.The results showed that the content of Mg in flue-cured tobacco leaf was mainly affected by the independent effect of Mg.The content of B in flue-cured tobacco leaf was affected by both the independent effect of B and the significant Mg-B interaction,and the Mg-B interaction was the greatest when the application rate of Mg fertilizer was 180 kg/hm^2.The application rate of Mg fertilizer had very significant effects on the yield,output value and superior-middle proportion of flue-cured tobacco.The application rate of B fertilizer had significant effects on the output value and superior-middle proportion of flue-cured tobacco.The combined application of Mg and B fertilizer had a significant interaction on the output value of flue-cured tobacco,and this interaction was the largest as the application rate of B fertilizer was 30 kg/hm^2.Under the field red-soil condition in Xuanwei city,Yunnan province,the optimum combined application rate of Mg and B fertilizer was 180 kg/hm^2 Mg fertilizer and 30 kg/hm 2 B fertilizer.The best application method was as follows:50% Mg fertilizer and 100% B fertilizer were used as basic fertilizer;the rest 50% Mg fertilizer was root-irrigated on the 30th day after transplanting.
