喷施除草剂要求严格掌握剂量,使药剂均匀分布、尽量减少雾滴飘移,在保证施药质量、提高防效和避免药害的基础上,减轻劳动强度,提高工效。目前农村的通用式手动喷雾器难以达到这些要求,需要有适于施用除草剂的喷雾工具。 发达国家喷施除草剂多应用扁扇形喷嘴,组合多喷头进行宽喷幅作业。我国南京农业机械化研究所研制成功的N110系列机
Spraying herbicides requires strict control of the dose, so that the drug evenly distributed to minimize droplet drift, to ensure the quality of pesticides to improve control and avoid injury, based on the reduction of labor intensity and improve work efficiency. The current general-purpose hand-held sprayers in rural areas are difficult to meet these requirements and require spray tools suitable for the application of herbicides. Developed countries spraying herbicides multi-application flat fan-shaped nozzle, a combination of multi-nozzle for wide spray job.
