摘要
穴盘精量播种机是工厂化设施园艺生产的关键设备。目前,国内农机市场缺少价格低、操作简单、效果好的气吸式穴盘播种机。为此,研究了气吸式穴盘播种器在不同类型蔬菜种子、气室真空度和吸种盘孔径条件下的播种性能,并在播种试验台进行了性能试验,得出了不同种子播种性能与气室真空度和吸种孔径的关系;同时,结合多方面实际因素设计,为开发适合我国国情的气吸式精量播种机提供了理论基础。
The plug precision seeder is the key device of factrory establishment and gardening production. At present, it is lack of air-suction plug seeder with low price, simple operation. Hence, the planting performance of the air-suction plug seeder is researched to meet different vegetable seed, vacuum of air room, and hole of suction seed plate. Then, it is tested on the seeding testing platform. The relationship between of different seeding properties of seed and the hole of suction seed is found. At the same time, considering many practical design factors, the theory is put forward to develop the air-suction precision seeder.
