北方粳稻“植生带”育秧设备定向排种装置的研制

The Development of Northern Japonica Directional Metering Device of “Vegetation Zone” Seedling Equipment

为满足超级稻每穴(2±1)粒种子精量播种的特殊农艺要求,在纸夹定位水稻精密育秧设备研究基础上,研发出一种新型超级稻定向排种装置。初步排种试验表明,该装置可将种箱中杂乱无章的稻种分离出来后,在组合滑道上逐渐沿其长轴方向排列成连续的种子流,为超级稻植生带育秧设备的研制提供理论与实践依据。

In order to meet specific agronomic requirements of per hole 2 ± 1 precision sowing of the super hybrid rice seeds, based in the rice seedlings devices of the precise localization by paper, developed a new type of directional metering devices. Initial seeding experiment showed that a continuous flow can be formed gradually along the long axis of the seeds lying in a combination of slide, after the haphazard rice seeds in the box can be isolated by the device, providing for the foundation of the theory and practice for the development of the super rice seedling equipment.
