由于巨菌草种苗个体间直径差异较大，导致在其短茎扦插繁殖的排种器排种过程中频繁出现卡种及排种不连续等问题。针对上述问题，设计了一种新型多轨单排复位式巨菌草排种器。通过对排种器各关键部件的建模和分析，以及多层复位弹簧的调试，优化并确定排种器各层 K 值方程，推导出各层滑轨长度及与卡板的角度，成功实现了排种器满载时各层卡板竖直于同一垂面，从而使得储种、排种及导种的有序进行。同时，对排种器质量和体积参数进行了优化，得出体积和质量参数与弹簧弹性系数影响不大的结论，从而可最大限度地利用排种空间，提高单个排种器的储种量。

Due to larger diameter difference in seeds of Pennisetum sp.,there is plugging and incontinuity, which fre-quently emerge in seeder for Short stem cuttings propagation.Aiming at these problems,a kind of Multi-track and single-row resetting type Seeder is designed for Pennisetum sp.Through modeling and analysis of each key components on seeder metering device and debugging multilayer resetting spring,K value equation is optimized and determined for seeder metering device,each layer slide track length and the angle between card board and slide track is deduced.Each layer card board being in the same vertical surface is realized when seeder is full load, so as to makes seeder-storing, seeder-metering and seeder-guiding sequential.Further, the quality and volume parameters of seeder is optimized, and it is concluded that volume and quality parameters have little effect on spring elasticity, which could maximize the seeding space and quantity in single type seeder.
