对环境的日益关注和果树管理方式的变化,促使了新型果园防飘喷雾机械-隧道式循环喷雾机的发展。文中详细介绍了隧道式循环喷雾机的2大系统,即,药液回收循环系统和药液喷施系统,以及科学家针对隧道式循环喷雾机在雾滴沉积特性、药液损失、药液回收率和生物防治效果等方面所作的研究,提出了在我国发展隧道式循环喷雾机的意义和重要性。 Growing concern for the environment and changes in the way fruit trees are managed have led to the development of a new type of orchard spray-resistant sprayer - a tunnel-type circulating sprayer. In this paper, the two major systems of tunnel circulating sprayers are introduced in detail, namely, the liquid recovery cycle system and liquid spraying system, as well as the scientists for the tunnel circulating spray machine in the droplet deposition characteristics, liquid loss, liquid recovery And biological control effect made by the research, put forward the significance and importance of the development of tunnel circulating spray machine in our country.
