摘　　要：穴盘精密播种机的种类及形式较多,当前发展的主流是气吸式播种。分析比较了各播种原理和形式的优缺点,结合林木穴盘育苗的应用,对林木穴盘精密播种机选型进行研究,对排种器的结构形式提出改进并给出结构设计方案。There are numerous kinds of tray precision seeders and an air-suction seeder is the main type currently. The principles, advantages and disadvantages of each kind of seeders are analyzed and compared. Based on the development and application of forest tray precision seeders, the study on the type selection of tree tray precision seeders is made, an improved design of the structural form of seed sowing equipment is presented, with relevant design plans put forward.
