| 摘 要： | 目的]比较喷雾和灌根施药方式下吡虫啉在烟草植株的吸收传导分布规律.方法]进行温室盆栽试验,采用液相色谱-质谱联用方法测定施药不同时间烟草根、茎、上部叶、中部叶、下部叶中吡虫啉含量.结果]灌根施药方式下吡虫啉能被烟草根部吸收并转运至植株各个部位,而喷雾施药在烟草叶片上原始沉积量较大,通过内吸作用传导至烟草其他部位的含量较低.结论]灌根施药在烟草植株内输导分布更加均匀,持效期更好,喷雾施药能较好的作用于叶片部位,速效性更好.

| Abstract: | Objective] To compare the translocation and distribution of imidacloprid in tobacco with spray and root irrigation application methods.Methods] Pot experiment in the greenhouse was carried out,and LC-MSMS was used to determine the content of imidacloprid in different parts of tobacco plants (roots,stems,the upper,middle and lower leaves) at different time.Results] The imidacloprid could be absorbed by root and could be transported to all parts of the tobacco plant after irrigating root,but the original deposition amount was larger and the transport efficiency was lower after spraying.Conclusion] The translocation and distribution of imidacloprid by spraying was more uniform and the holding efficiency was better,but imidacloprid with root irrigation could act on leaf directly,and had better readily availability. |
