摘要
为解决烟蚜茧蜂繁育过程中烟株叶面间湿度过大,繁育用人工成本过高的问题,设计了低湿度烟蚜寄主作物繁育装置,并进行繁育效果验证。结果表明,通过低湿度烟蚜寄主作物繁育装置繁育烟苗及烟蚜茧蜂较盆栽育苗和湿润育苗分别降低叶面间湿度16.65%和21.54%;单位面积增加烟蚜茧蜂繁育量5.22万和1.69万头/m^2;降低蚜霉病发生率2.51%和10.87%;降低烟蚜茧蜂繁育人工用时0.236和0.283 h·人/万头;降低繁育成本4.41和10.31元/万头。该装置具有一定的推广应用价值。
In order to solve the problem of excessive humidity in leaf surface and high artificial cost in the breeding process of Aphidius gifuensis,the host plant breeding equipment of Myzus periscae with low-humidity was designed. The effect was verified by comparing with traditional breeding methods. The results indicate that compared with the potted seedling and moist tray seeding,by using the low-humidity equipment,the humidity between the leaf was reduced 16. 65% and 21. 54% respectively. The number of Aphidius gifuensis breeding in the unit area was increased 52 200 per m2 and 16 900 per m2 respectively. The incidence of aphid mildew was reduced 2. 51% and 10. 87% respectively. The labor time of breeding ten thousand Aphidius gifuensis was reduced 0. 236 h and 0. 283 h respectively. The cost of breeding ten thousand Aphidius gifuensis was reduced 4. 41 yuan and 10. 31 yuan respectively. This equipment has certain application value.
