脱粒

The results show that under the same condition, it's easiest at corn bottom fringe to thresh, the second is at top fringe and the last is middle fringe;the longitudinal bending force is the optimal forcing method for threshing.

结果表明：在同样试验条件下，玉米穗大端籽粒脱粒较容易，小端次之，中部较难；纵向弯曲力小于侧向弯曲力，侧向弯曲力小于压力；种子玉米脱粒时的最佳施力方式为纵向弯曲力。

When young, I was appointed to wheat straw into a haycock when harvesting time came, that's to say, putting wheat straw at the right place after it was thrown to me, since a haycock was usually too high for one person to manage.

小时每年秋天为小麦脱粒时，都由我负责垛麦桔，即将麦子脱粒后的桔杆垛成垛，因为麦垛通常很高，打到后来下面的人够不着，就只能一人负责向上挑，一人在上面负责将挑上来的麦桔放好，我就是负责在上面放麦桔的人。
