外凸球形穴水稻植质钵育秧盘气吸式播种机设计及试验研究

Design and experimental research on backbowing spherical cavity air-suctiong seeder for sowing rice in cupulate compartment tray of plant material

以植质钵育秧盘为基础,按照水稻植质钵育播种的要求,对外凸球形穴水稻植质钵育秧盘气吸式播种机进行设计和关键参数的分析,得出了吸种盘在试验中较优的结构参数组合,使农艺指标达到较佳。

Taking cupulate compartment tray of plant material as basis, according to the seeding request of paddy rice which was grown in eupulate compartment tray, the backbowing spherical cavity aspirating seeder was designed and the key parameters were analyzed.Then it obtained the better structural parameters combination of the suction plate in the experiment, and it made the agronomy index come to a better condition.
