摘　　要：水稻直播机械以作业速度快、成本低、标准化程度高成为优势,因此根据水稻标准种植农艺要求,采用旱育稀植垄作精量穴播技术,结合侧深施肥作业模式,研制了一种水稻精量穴直播机。设计了气吸式水稻精量排种器的核心部件种子分离盘,实现了精量穴直播;采用气送式槽轮排肥器,施肥深度50 mm。田间试验表明:该装置穴粒数合格率≥90%,播种深度合格率≥80%,穴距合格率≥80%,破碎率≤0.5%,性能指标优于行业标准。The dry direct seeding rice has the advantages of fast running speed,low cost and high degree of standardization. Against the given agricultural requirements of rice standard,rice precision points direct seeding machine was developed by using of dry raising seedling and thin spacing transplanting techniques. The rice seeds were hill-dropped into the small furrow on the ridge. A special designed seed separationdisc was used to control the amount of sowing seeds. A special tround row of fertilizer type of gas transport fertilizs depth of 50 mm. Field trials show that the modified device can be met with average grain of 3-4 per hole,the qualification rate is 90 %; sowing depth of the qualification rate is 80 %,the breaking rate was less than or equal to 0. 5 %,field trials show that the performance of the modified device far exceeds the industry standard.
