    摘要:

    基于針吸滾筒式排種器設(shè)計(jì),，對(duì)吸種理論進(jìn)行了分析,。針對(duì)雜交稻遼鹽188芽種進(jìn)行了播種試驗(yàn),。試驗(yàn)表明,，針吸式排種器設(shè)計(jì)滿足播種雜交稻芽種的超低播量和低傷種率要求,。通過(guò)對(duì)試驗(yàn)結(jié)果的分析表明,，影響排種器播種性能的因素主次順序依次為真空度,、吸針端面角和滾筒轉(zhuǎn)速，且在滾筒轉(zhuǎn)速為5r/min,、吸針端面角度為30°,、滾筒內(nèi)真空度為4.8kPa時(shí)，播種效果最好,。

    Abstract:

    Structure and seeding theories of the rice precision needle-like vacuum seeder was introduced. The experimental results for hybrid rice indicate that the seeder is capable to meet the requirement of precision seeding and low rate of damaged seed. The analyses of the experimental results indicate that the vacuum value is the most important factor, the angle of the needle top and rotate speed of the roller follow. The optimum operation condition with the level of factors as follows: vacuum value 4.8kPa, the angle of the needle top surface 30°and rotate speed of the roller 5r/min.
