为提升烟叶种植效益和烟叶质量,本试验结合山东潍坊当地实际,通过烟蒜轮作种植模式与烟麦轮作、常规烟叶种植模式等轮作模式对比,探索烤烟-大蒜轮作在烟叶培育过程中对烟叶产质、整体种植效益的影响,并探索此种模式的运行机制,为烟农在烟田轮作中选择一种有益增收的轮作模式提供较为合理的数据支撑,试验结果表明,烤烟大蒜轮作使整体烟叶的种植效益得到较大提升,烤烟的产值相较常规烤烟种植要高于1.87％,轮作模式综合种植效益要高于烟麦轮作33.22％,对提高烤烟产量和综合种植效益具有明显优势.

目的:研究雅苒增效肥对烤烟性状指标及产质量的影响.方法:以中烟101为原料,开展大田试验,记载分析各小区烟株农艺性状、化学成分和产质指标.结果:①雅苒增效肥相对利用率高,能有效促进烟生长发育,特别在大田前中期效果尤为明显.②施用雅苒增效肥,对烤后烟叶产质量有一定正向影响,控制复合肥用量减少20％,烤后烟叶产量、品质表现及综合产值优于常规施肥;施肥总量减少40％,烤后烟叶产量略有下降,但化学成分差别不大.③雅苒增效肥可明显降低烤后烟叶氯离子含量,降幅至少达40％以上,总氮、烟碱等化学成分指标不同程度好于常规施肥,在改善烟叶刺激性和余味方面作用明显.

为验证激健农药减量助剂的功效,开展了激健农药减量助剂防治烟草烟青虫效果研究试验.结果 表明,激健助剂农药减施技术防治烟草烟青虫效果较好.供试药剂在试验剂量范围内对作物安全,且激健助剂可减少农药对烟草的伤害,提高烟草免疫力,促进烟草生长,降低烟草农药残留,提高烟草品质和产量.

依托石家河黄烟专业合作社,利用闲置期烤烟育苗大棚进行蔬菜无土栽培.本文在介绍合作社概况的基础上,对蔬菜无土栽培技术及营销模式进行探讨,以辐射带动产区烟农增收.

为改进完善湿润育苗技术,实现湿润育苗本土化,对湿润育苗及其补水方式进行研究,对比一次性注水后期补水、长流水补水等2种补水方式对湿润育苗环境温度、烟苗生长发育、成苗素质等方面的影响.结果表明,与漂浮育苗相比,湿润育苗出苗早、出苗率高、整齐度高,由于湿润育苗较漂浮育苗水温高,烟苗生长相对较快,可缩短烟苗生育期7d左右;而在补水方式上,长流水方式烟苗长势较慢,一次性注水后期补水方式烟苗长势明显.

2014—2015年昌乐县开展性诱剂诱捕烟青虫和棉铃虫试点试验,2016年在全县烟田推广应用,6—7月通过调查5个烟站共10处棉铃虫和烟青虫的诱捕量.结果表明:使用性诱剂防治棉铃虫和烟青虫效果显著,可以减少化学农药使用量,改善生态环境,全面提高农产品质量,具有良好的推广应用前景.

To search for substitutes of chemical fertilizers and chemical pesticides in the production of strong flavor type tobacco, biogas slurry was applied in Zhu Cheng. An Qiu and Gao Mi. The results showed that biogas slurry can promote the growth of tobacco seedlings, enhance the stem height, stem diameter and root weight. The biogas slurry also can improve the agronomic characters of tobacco. The yield, market value, average price and proportion of superior tobacco were increased by 4.02%, 8.59%, 4.38% and 8.15% respectively by biogas slurry application compared with the control. The appearance quality of tobacco however, was not changed. Biogas slurry showed good control effect on Myzus persicae as well as tobacco virus disease, black shank and brown spot, with the incidence rates of the 3 diseases were reduced by 59.96%, 55.56% and 19.05% respectively. In conclusion, biogas slurry can promote the growth of tobacco, control tobacco diseases and pests, and improve tobacco quality.
