走系统工程之路加快玉米联合收获发展步伐

对玉米联合收获机推广应用较多的山东、山西及河北等省的玉米联合收获机试验情况进行了研究分析．其结果表明，影响玉米联合收获机推广的诸多因素中，最为关键的因素就是行距的适应性问题。为此，结合小麦联合收获机推广经验，指出了加快玉米联合收获机推广应用速度的关键是实现玉米生产过程机械化，而在小麦玉米一年两熟地区则要从小麦的种植规格入手，即实现小麦玉米全过程的机械化；并将系统工程的方法运用于种植收获的全过程，真正实现优质与高效的现代化农业生产。

Picking Step of the Development of Corn Combine Gain by Systems Engineering

This paper analyzes testing result of the corn combine of the representative province such as Shandong, Shanxi, Hebei, and so on. Turning up the pivotal factor of a good many factors, which affect the generalizing of the corn combine; this is the problem of the row spacing adaptability. Referring to the generalized experience of the combine harvester, the viewpoint is put forward, that is what of the pick up key of the step of development about corn combine gain is coming true process mechanization of the produced corn. And, in area of wheat and corn rotated, the work is started with the wheat planting, i.e. coming true all process mechanization of the production of wheat and corn rotated. By dint of the method of systems engineering, it is optimized all process from planting to gain. That is realizing modernization agriculture yield of high quality and high benefit.
