施特灵等4种药肥对烤烟抗病性及产质量的影响

目的]研究施特灵等4种不同药剂对烤烟抗病性及烟叶产质量的影响。方法]通过5个处理,3次重复的大田试验研究了4种药剂对烤烟抗病性及烟叶产质量的影响。结果]参试药肥对烟草生长安全。毒消500倍液和施特灵600倍液对烟草病毒病（以CMV为主）的预防效果最好,发病盛期其对烟草病毒病的防效达45.54%和37.46%,其次是茂丰2 000倍液和叶根宝600倍液,其对烟草病毒病的防效分别为31.57%和24.29%。不同药肥处理的烟株农艺性状及初烤烟叶产值、产量等各项指标与对照差异不显著。各药肥处理对于改善烟叶主要化学成分均有一定作用。各药肥处理的烟叶在香气质、香气量、吃味、杂气等指标上均略有改善。结论]该研究为在烟草种植中施用药肥提供了理论依据。

Experiment on the Influences of Four Mixtures of Insecticide and Fertilizer Including Oligosaccharin on the Disease Resistance and Yield and Quality of Flue-cured Tobacco

Objective] The purpose was to study the influences of 4 different insecticides including oligosaccharin on the disease resistance of flue-cured tobacco and the yield and quality of tobacco leaves.Method] The influences of 4 insecticides on the disease resistance of flue-cured tobacco and the yield and quality of tobacco leaves were studied through the field experiment with 5 treatments and 3 repeats.Result] The tested mixtures of insecticide and fertilizer were safe to the growth of tobacco.The control effects of Duxiao diluted for 500 times and oligosaccharin diluted for 600 times on tobacco virus disease(with CMV as major) were best and their control effects on tobacco virus disease reached 45.54% and 37.46% in the peak period of the disease,that of Maofeng diluted for 2 000 times and Yegenbao diluted for 600 times were secondary and their control effects on tobacco virus disease were 31.57% and 24.29% resp.The indices including agronomic charaters and yield value and yield of preliminarily cured tobacco leaves of tobacco plants treated with different mixtures of insecticide and fertilizer had no significant difference from that of CK.All the treatments with mixtures of insecticide and fertilizer had some effects on improving the main components of tobacco leaves.The indices including aroma quality and quantity,smoking quality and offensive odor of tobacco leaves treated with mixtures of insecticide and fertilizer got a little improvement.Conclusion]The study provided theoretical foundation for applying mixtures of insecticide and fertilizer in tobacco planting.
