近年来,为了解决针叶树育苗中鸟害严重的问题,我们在本县南山进行落叶松育苗时,坚持采用了砷酸铅拌种的方法,收到了显著的效果。具体办法是:在落叶松种子浸种催芽消毒之后,播种前,用可湿性砷酸铅粉剂拌种,每百斤种子用药4—5斤。砷酸铅是广谱性的胃毒杀虫剂,剧毒,粘着性极强。因其为白色粉末,为防人畜误食,着以红色更好。幼苗出土后种壳粉红色,披了一层伪装,这样既迷惑了鸟雀,又会毒杀咀嚼式口器害虫,使幼苗安然无羌。针叶树育苗利用砷酸铅拌种防鸟害,能节约大量人力物力,方法简便易行。过去育
In recent years, in order to solve the problem of coniferous tree nursery seedling serious problems, we carried out in the county Nanshan larch nursery, insisted the use of lead arsenate seed dressing method, received a significant effect. The specific approach is: Lactarius seed soaking germination and disinfection before sowing, with wet lead arsenate powder dressing, per kilogram of seed medication 4-5 pounds. Lead arsenate is a broad spectrum of stomach poisoning insecticide, highly toxic, very strong adhesion. Because of its white powder, to prevent human and animal eating, with red better. After the seedlings were planted pink shell, draped a layer of camouflage, so that both confused birds, but also to kill chewing mouthparts pests, seedlings Enron no Qiang. Conifer seedling use of arsenic trioxide bird seed dressing, can save a lot of manpower and resources, the method is simple and easy. Past education
