| 摘 要： | 摘要：为了避免因收获机罩壳内部种子残留与混杂所带来的育种试验数据失真问题，结合自行研制的4GX-100型小区小麦种子联合收获机进行田间育种收获试验，利用二次回归正交旋转试验设计，探讨了无滞种残留率与脱粒滚筒转速、喂入量、吸杂风机转速的关系，建立了各个作业参数与无滞种残留率之间的数学模型。由试验结果分析可得：3个因子对无滞种残留率影响大小的顺序为脱粒滚筒转速、喂入量、吸杂风机转速；通过方程模拟选优得出4GX-100型小区小麦种子联合收获机田间育种收获关键作业参数的最优组合为：脱粒滚筒转速1 586 r/min、喂入量为0.305 kg/s、吸杂风机转速1 076 r/min，即无滞种残留率为最大值99.98%，且收获机其余各项指标满足小区育种收获要求。

| Abstract: | In order to avoid the distortion of breeding test data caused by remnant and mix of seeds in the internal shell cover in harvest process, adopting field breeding harvest test with self-developed 4GX-100 type cropland plot wheat seeds combine harvester, using the quadratic regression orthogonal rotational combining design, the relationships of no seeds remain rate with threshing cylinder rotation speed, feed rate and suction fan rotation speed were studied, and the mathematical model between operating parameters and the no seeds remain rate was established. The result showed that the effect degrees of 3 factors on the no seeds remain rate was as following: threshing cylinder rotation speed > feed rate > suction fan rotation speed. Through the simulating excellent-choosing equation, the best parameter combination under the field breeding harvest experiment conditions was obtained as following: the threshing cylinder rotation speed was 1586r/min, the feed rate was 0.305kg/s, the suction fan rotation speed was 1076r/min, and the no seeds remain rate was achieved maximum of 99.98%, at this time, which could meet the needs of plot seeding harvester. |
