施用不同肥料对烤烟生长发育及产质量的影响

摘要

通过田间试验,设置施用土壤连作调理剂、复合微生物肥和腐殖酸钙3个处理,以常规处理为对照.分析施用不同肥料对烤烟物理指标、初烤烟叶化学成分、烟叶产量与产值以及烟叶收获后土壤养分的影响,结果表明连作土壤调理剂、复合微生物肥和腐殖酸钙的施用可以促进烤烟苗期根系的生长,为后期优质优产烟叶打下良好的基础,同时还能降低烟株感病的风险.%Compared with conventional treatment, using soil continuous cropping conditioner, compound microbial fertilizer and humic acid calcium through field experiment. We analyze the impact of the physical indexes, the chemical composition, the yield and the output value of flue-cured tobacco under different fertilizers. The result shows that using soil continuous cropping conditioner, compound microbial fertilizer and humic acid calcium can promote the growth of root system during seedling stage, which gives a good foundation for the superior quality of tobacco leaves, and reduce the risk of tobacco plant disease at the same time.
