播种机

This benefit was obtained by using a moldboard plough to prepare the soil in the pre-monsoon period in June.

这种好处由6月季风季节之前用有壁犁整地翻耕得到，然后土地在季风季节休闲直到11月种麦。1983年有壁犁耕翻（30厘米深）的效果与深松犁（45厘米深）、凿形犁（25厘米深）和农民的播种机（10厘米深）加以比较，只有有壁犁的效果明显好于播种机（Khan等，1986）（图1）图1。

In order to find out primary and secondary factors influencing the power dissipation of corn rootstalk treatment device of no-tillage planter, soil-bin experiment was carried out in the laboratory. The power dissipation model of the device was set up based on the quadratic regressive orthogonal test of the influencing factors.

为找出影响免耕播种机玉米根茬处理装置的功率消耗的主次因素，对新研制的免耕播种机玉米根茬处理装置进行了室内土槽试验研究，对影响作业功耗的因素采用二次旋转回归正交试验，建立了玉米根茬处理装置的功耗模型。

The working performance of 2TYB-450 rice seeder for breed seedling in field was superior to that of other 2 kinds of seeders.

结论］2TYB-450型水稻田间育秧播种机的作业性能优于其他2种播种机。

The working performance and quality index of 3 seeders were determined and the performance indexes such as the eligible ratio and blank-hole ratio of sowing,and the sowing seed number per seedling a...

通过播种机的性能对比试验，测定3种播种机的作业性能和质量指标，综合分析3种机型的播种合格率、空格率、每取秧面积播种粒数等性能指标。

Adopt the agricultural machinery of electromechanics' integrated technology , the performance of the great improvement agricultural machinery, at present, foreign more and more seeders adopt electromechanics' integrated technology, have improved the working dependability of the seeder, simplified operating, lightenning labour intensity, reducing auxiliary time, raising labour productivity

采用机电一体化技术的农业机械，极大的改进了农机的性能，目前，国外越来越多的播种机采用机电一体化技术，提高了播种机的工作可靠性、简化操作、减轻劳动强度、减少辅助时间、提高劳动生产率。

Result 2TYB-450 rice seedling seeder adopted the synchronous driving wheel, the equipment for vibrating and homogeneous sowing and the guiding sowing plate with seed box cross, so it didn't slip when driving and had high eligible ratio of sowing, good effect of filling seeds, less sowing seed number per seedling area and high working stability, with the sowing eligible ratio of 68.67%, the sowing blank-hole ratio of 1.89% and the sowing seed number per seedling area of 4.19. The working performance of 2FBS-840 seeder was next and that of MR-BZ840A seeder was worst.

结果］2TYB-450型播种机采用同步驱动轮、振动匀种装置、种箱交叉导种板，驱动不滑移，播种合格率高，充种效果好，每取秧面积播种粒数少，工作稳定性高，其播种合格率为68.67%，空格率为1.89%，每取秧面积播种粒数4.19；2FBS-840型播种机的作业性能次之，MR-BZ840A型播种机的最差。
