摘要 为选择适宜的镁肥用于烤烟生产,通过大田试验研究了不同种类镁肥对烤烟生长发育和烟叶产质量的影响。结果表明:在等量镁的情况下,施用镁肥可以明显增加叶片面积,提高烟叶单叶重和产值;施用MgO处理的产值较对照提高了18.61%;施用MgSO 4的效果最差;施用镁肥可以促进烤烟化学成分更加协调、提高烤烟感官评吸质量;但不同镁肥效果有所差异,各处理中以施用MgO效果最优,其产量、产值和均价分别比对照提高了7.04%、18.61%和11.20%,X2F、C3F和B2F平均单叶重分别比对照提高了11.51%、3.49%和8.37%,感官评吸综合得分提高了1.6分;施用MgCl2的感官评吸质量最差且低于对照。因此,在福建烟区烤烟生产上镁肥以施用MgO为宜。 In order to select suitable magnesium fertilizers for flue-cured tobacco production,the field experiments were conducted to study the effects of different magnesium fertilizers on on growth,development,yield and quality of flue-cured tobacco.The results showed that application of magnesium fertilizer could significantly increase leaf area,leaf weight and output value of tobacco leaves in the case of equal amount of magnesium.Compared with the treatments without Mg application,the tobacco value of treatments with magnesium oxide(MgO)was increased by 18.61%at the same amount of Mg application,while the value of treatments with magnesium sulfate(MgSO 4)was the worst.The coordination of chemical components and the evaluation of sensory quality of flue-cured tobacco were promoted with Mg application.The efficiency of different kinds of Mg fertilizer was different.The treatment with MgO had the best effect.The yield,output value and average price of the treatment with MgO were increased by 7.04%,18.61%and 11.20%,respectively,and the average leaf weight of X2F,C3F and B2F increased by 11.51%,3.49%and 8.37%,respectively,compared with the control.Comprehensive sensory evaluation score of flue-cured tobacco increased 1.6 point under MgO treatment.The worst evaluation of sensory quality was observed under magnesium chloride(MgCl 2)treatment which was lower than the control.Our findings suggested that the MgO fertilizer should be preferred in Fujian flue-cured tobacco production.
