有机肥与中微量元素配施对烤烟产量及品质的影响

为了寻找烤烟有机肥与中微量元素混合施肥的理论依据,研究了有机肥与不同中微量元素配施对烤烟生长发育及产质量的影响。结果表明:与常规施肥CK相比,酒糟与中微量元素(B、Zn、Cu、Mg)肥料配施能使烤烟生育期提前3 d,促进烟株生长发育,降低病害发生率,其青枯病、病毒病发病率分别降低74.8%、80.2%,产值及上中等烟比例分别提高6.7%、2.7%,显著提高了烤烟的产量及品质,可大面积推广应用。

Effects of Organic Manure and Medium-Micro element Combined Application on Yield and Quality of Flue-cured Tobacco

In order to search the theoretical basis for the mixed fertilization of organic manure and mediumand micro-element in flue-cured tobacco.A field experiment was conducted to investigate the effects of organics and medium-and micro-element combined application on growth and development,yield and quality of flue-cured tobacco.The results showed that organics and medium-and micro-element (B,Zn,Cu,Mg)combined application reduce 3 day in the growth period of duration compared with conventional fertilization (CK).Promoted the growth and development of tobacco plant,reduced the incidence of disease.The incidence rate of bacterial wilt and virus disease were decreased by 74.8％ and 80.2％.Output value,the proportion of secondary smoke were increased by 6.7％ and 2.7％.The yield and quality were significantly improved of flue-cured tobacco.Organics and medium-and micro-element combined applicationcan be widely applicable.
