    摘要:

    采用田间试验研究了Mg肥施用对皖南烟区烤烟生长发育及产质量的影响。结果表明:适量施用Mg肥能有效促进烤烟生长发育,提高烟叶产量,同时较好协调烟叶中主要化学成分,改善烟叶品质;施Mg量为300 kg/hm2 MgSO4·7H2O时,烤烟的农艺性状、干物质积累及产质量达最佳。

    Abstract:

    The effects of magnesium fertilizer on flue-cured tobacco growth and development, yield and quality in south Anhui was studied by methods of field experiment and lab analysis. The results showed that: rational application of Mg could promote the growth and development of tobacco effectively, and improve yield, balance the chemical components of tobacco leaves and as a result the quality of tobacco leaves were improved. Under the condition of this experiment the optimal Mg application was 300 kg/hm2 MgSO4·7H2O, and the agronomic characters, all of dry matter accumulation, yield, and tobacco leaf quality were the best.
