北方粳稻“植生带”育秧设备定向排种装置的研制

摘要

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 mete-ring 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 .
